Carburetor vs Fuel Injection for Long Motorcycle Trips! 

My first three bikes were carbureted. Chinese, Honda, and Kawasaki. After many misadventures (mainly with Chinese and Kawasaki), two things happened. First, I gained very extensive knowledge about carburetors and how to maintain/repair them on the road. And the second thing, I will never ever use that knowledge again. I won't forget, when I tried to open the malfunctioning CVK carburetor on my KLR 650, everything just fell apart in my hands. Turns out, the mechanic (who was supposed to check my carb earlier) broke a vacuum spring, damaged the vacuum hose, few screws were stripped, and then I was... screwed. Or carbureted. I "fabricated" a few screws (zip ties and some nails), "glued" spring together (zip ties, adhesive tape), plugged vacuum hose with tape, and returned home burning twice as much fuel as usual. CVK carbs can be pretty complicated pieces of sh... Comparing to them, fuel injection is much simpler and harder to break. Happy owner of fuel-injected Honda CBF. 20 000 km without any trouble. For someone coming from carbureted bike, this is mind-blowing. And yes, I'm always packing spare fuel pump. If something is gonna be wrong with fuel injection, it will be the fuel pump. Easy to repair.

With fuel injection, realistically your only problem will be the fuel pump, which usually fails because of poor quality fuel full of muck. A good filter system will keep ahead of the problem most of the time. Changing jets and raising or lowering needles is a faff and often trial and error. Never an issue with fuel injection. For me it's not a choice really. But to each their own. Happy travels

I love your no-nonsense, no BS reviews. Real facts, straight from the trenches. Extremely valuable. Thanks!

Fuel injection also normally comes with other things on bikes to make the ECU operate properly to control the injector. Altitude/air pressor sensor that can be easily damaged, but normally well protected. Or an alternative a mass airflow sensor, possible o2 sensor. While I would say those failures are less than a fuel pump, but still common failure points and adds to a parts list for replacements. But I personally would still go fuel injection even though I can resolve a carb myself, you tend to constantly need to adjust it and clean it, unless you use it constantly and always have good clean fuel.

I've vowed to never own carbureted bikes some decade ago, and never regretted this decision.

I learned a lot from you. Thanks from Saudi Arabia🇸🇦

I can fix carburetors, cleaned them, rebuilded them with new membranes, orings and so on. But in my garage, not in the middle of the road. You just simply cannot bring spare membranes, rebuild kits, prings and a carb sync tool with all the other tools. Even a 30 year old carburetor is nothing like the one on a Simson or old Jawa, and you need to pull all fairings, fuel tank and airbox even to have a look. Not even telling about starting it up after few months, and the possibility if that your carbs fail, fuel easily gets mixed with oil and before you know it, you can have serious engine bearings failure.

Fuel injection is the one for me ,and I have this on my air/oil cooled bike . I understand that others will like carburetors and that is great because they will be riding the bike of their choice . In the past my bikes have had carbs but I wouldn't return to them .Great topic Pavlin .

Carbs are always a compromise at certain points throughout the rev ranges too. Fuel injection is much more reliable than it ever was. But, carbs can run badly forever lol.

Pavlin you are the best, another great video ! And I absolutely love your Bulgarian accent, your English is perfect! Greetings from Greece !

yes, your right about everything, have spare coil on my R1150R, injectors is checking when ride or when maintenances bike, but my pump is in the tank, think when you get spare pump I need to have another thank for 15-20l fuel, carburetors on the trip long time ago on my friend bike become so dirty they stopped running, all four clean with water, assembly bike, not perfect but another 400km we are home

Older bikes have carbs and work well when sorted. I know how to fix and maintain mine. I don’t ever need a mechanic as I have taught myself to clean and tune my carbs. . It’s not hard to sync carbs but you have to make sure you have no air leaks first. I agree with you not many people can work on their own carbs. It’s a dying skill. Newer bikes have injection systems and are mainly trouble free. Cheaper to produce and less service work. On the whole I agree with your comments.

Modern EFI is usually very reliable. I'm glad Kawasaki went EFI on the 2022 KLR. Love easy cold morning starts with injection. Until I started watching your videos I had never actually seen anything about Bulgaria Your country is beautiful and someday I would like to see it in person. Please keep the videos coming

Hello komshu 🤝 (hope you didn't mind when i refer you komshu?) from a stormy Istanbul evening. Possibly same in your area. Just wanted to tell you Balcik in Turkish means mud puddle. Also; best wishes and thks again for keeping the community informed and focused during the covid period Murat

I find it so cool that you respond to every single comment. Keep up the good work! 😉👍🏼

I totally agree on your points about fuel injection system. More economical and stress free. Broken fi system is very rare.

I would not be surprised if a lot more visitors came to the Black Sea resorts of Bulgaria after watching this video.

Thanx, this segment provided was a good "did you know" inclination about carburetor and fuel injection. I can vaguely remember back in the late 1970s when I was a teenager, I used to cut large lawns full of grass using lawnmowers with carburetors. I had learned how to troubleshoot those kinds of engines from a course in high school. As a matter of fact, small engine mechanics was the only knowledge I acquired of any kind of mechanical engineering at that time and haven't worked on an engine since then, I focused more on playing sports from the 1980s onward. Not until recently, in my mid 50s, have I gotten back into riding motorcycles and the modern sophisticated engines are far beyond my knowledge. Anyway, I understood most of your carburetor pros/cons and could relate to adjusting the governor so to perfectly set the flow of gas to the engine in order for it to run smoothly without sputtering and eventually shutting off; it took a little time to learn. I have so much to learn about the new technology as I haven't logged that many miles on my bike yet; it hasn't broken down on me--yet! I do have long distance travel goals set for the near future. I may not always comment on all your posted videos; however, I watch them 95 percent of the time. I feel more comfortable watching your videos than riding my motorcycle to gain experience. Yes, I know watching videos aren't going to improve my riding skills. Perhaps by watching your videos will add to my natural instincts when I need to apply any immediate safety measures in the future, which I hope to never have to do. Be safe!

*INFORMATIVE VIDEO I TOTALLY AGREE! my personal experience: fuel injector does NOT like water (washing bike or riding through water), fuel injector electric connector gets short circuit because of the water, if not sealed correctly. of course, I envy my motorcycle friends, who know how to adjust/fix carburetor). fuel injectors are okay (reliability) but fuel pumps can be a problem.*

Even though I’m in the top 10% you say can fix a carb, (it’s incredibly simple by the way) the real point is that the chances of finding someone in a remote area who can fix a carb is far higher than someone who has a computer with the correct software to diagnose issues with an EFI system. Too many models, and too high costs and updates to keep up. EFI bikes are now just cellphones on two wheels! And the reason you need a computer with the correct software, is because the majority of issues with an EFI systems are related to them not receiving the correct messages from the multitude of sensors designed to stop tiny Swedish Elf Puppets from crying. So carrying a spare injector and a spare pump is not going to be the solution, because it’s more likely to be a sender or a shorted wire from a sender that’s caused the fuel system to stop working. Furthermore, many of the parts for EFI systems are far more expensive than for carbs, some cost hundreds of dollars, euros etc. Then there’s the older EFI bike situation, whereby the parts are no longer available. And I’m sorry Pavlin, most carb bikes have a tank filter, and most serious bikers (especially those embarking on long trips to places with dirty tracks and potentially dirty fuel) have been fitting inline filters since the 1970s. It’s the most popular common sense modifications known to real bikers. I’ve fitted them to all my bikes for over 45 years. I do agree with what you say about the new breed of bikers who do not have a clue how to fix their bikes. But Darwin has a plan for them...🧐😎😜 Emissions legislation has made it IMPOSSIBLE for motorcycle manufacturers to build bikes with carbs and still comply with those regulations. We know this fact already. The way these things work is that climate lobbyists (working for the oil companies and banks) influence the fake carbon emissions peddling climate conferences, which in turn set targets; regulatory bodies set standards; then governments pass regulations; car and motorcycle manufacturers design solutions to cope with the new regulations. All the evidence is in plain sight. But everyone needs to make a higher profit to cover the cost of all that development work. So car and motorcycle manufacturers sell the diagnostic software to selected dealers, and as always, built in obsolescence takes care of the rest. More expensive parts that need to be replaced equals the greater likelihood that the owner will eventually break a bike and sell it for parts, then buy a new bike. Again, we have all the evidence. I used to own an advertising agency, so I’ve sat through far too many top level strategy meetings to not see this game for what it obviously is. My philosophy is simple: Reduce the number of things that can kill me. By ‘kill’, I mean literally take my life, and the life ANYONE or the operability of ANY THING upon which I rely. I once drove from the UK to half way up Norway (and back again several weeks later) in a Volvo with a blown engine block base gasket. I just removed the radiator cap to reduce the pressure from the water system to prevent water from entering the engine, and contaminate the oil. The radiator boiled low every few miles, so I refilled it with an improvised washer bottle from another car, operated by a spare switch on my dashboard. When that was empty, I refilled the whole system from bottles. That car did another 6,000 miles with that setup. The idiot that worked on my car disturbed the paper base gasket when he worked on the head, but failed to replace the paper base gasket. He tried to kill my car. I removed him from the equation, and found a solution. But if the wire from an exhaust sensor shorts to Earth, and the fuel management system refuses to allow the fuel pump to work, I have to find the issue in the dark??! Who’s the idiot then...? Me for buying an EFI bike! Even a drained battery (very common issue, especially with modern bikes that have USB chargers) can prevent the fuel pump from working. Can you jump start an EFI bike??? No. I rest my case. In the long term, there will be only electric bikes, all even more vulnerable to electronic, electric, fire and obsolescence issues, and those who kept their carb bikes. EFI is therefore a transitory solution ultimately designed to kill bikes as we know them. And of course electric bikes will kill ALL unsupported long distance remote travel, unless we believe that Andean villages will have the resources to install wind turbines, after all the lithium has been extracted by the giant corporations.

Hello. In my experience is the opposite. I have a 3000 usd Chinese motorcycle (carburated) and I already helped two BMW GS owners to reach the closest town because their fuel pump overheats with temperature of 40+C⁰. Maybe it was lack of correct maintenance. I really don't know what happened. But the facts are there. And it is hilarious to see their faces when they are helped by a 250cc low cost chinese motorcycle. Greetings from México

Very good points in your video. I have both. One being a Road King, single CV carb. I tuned it properly and it works great now in Death Valley at -200 ft to Pikes Peak at 14,000 ft while having the best power and fuel economy. No adjustment need in the last 50,000 miles around the country. Never had to do anything to it other than tuning it initially for more power. Over 100,000 miles. Fuel injection is not nearly as forgiving for bad fuel. The filters are finer to prevent clogging of injectors. Keep filters changed and carry a spare. For carb use a filter and carry a spare. My KTM has 2 filters inside the fuel pump so in the event of changing it the pump has to come out of the tank. Either remove the tank or drain the gas. I carry filters and a pump. If we ignore problems the fuel injection is tuned better. Carbs are going away due to EPA. Not all efi is great. Especially older ones.

Of course, based on your big experience, you said smart and logical things. My choice is for carburator. I accept some maintenance more than injection system in order to have better feeling with the accelerator comand, less times unforeseenable problems with electric and electronic components. About me the only disvatage for the carburator is the effects on lubrication (and so engine durability) of not perfect mixing ratio by this feed system compared to the always perfect (if good) injection system

I fully agree i have an XT500 ‘78 an XT600 ‘84 these a nice and simple bikes but for a long motorcycle trip i deffenitly take the XT660z. I can fix a carburator but only in my garage on the road it’s just to difficult. You can work at the 500 carburator on the road no problem but on the 600 there is no space so you need help. Nice video 👌🏽

Hey Pavlin, same temperature in southern UK on Friday February 5th was blown away by temperature 15C and spent all day riding first Fuel injection BMW and later carburetor fanatic casa. As long as the weather is good it doesn't really matter 😀😀😃😀😃 today Tuesday 9th we have 30cm of snow 🤔🤔 safe travels Pavlin

I love your trusty bike she owned my high respect. Me i know your chanel and your bike, however the new comers they don't know you and have no clue what bike you ride. Inform them in the description, your bike will thank-you😉she deserve it.

I largely agree, but i have to note that at least one of the tour companies running Royal Enfield Himalayans into the HImalayas prefers carb over EFI because there are apparently 2 items that con go wrong with the EFI which need spares to fix. These spares are not always around, so they prefer carb. Once it is jetted for altitude and cleaned every so often there is no problem. Just what I heard, but as I said, I still largely agree with you ;)

Yeah it's always become sexy topic for many years. Personally I see between carburetor and EFI has it's own adventeges depend on what kind of rider you are and where you gonna plan to ride. Like here in Indonesia carburetor spare parts is more easier to find, you always can find small workshop to fix it even in the middle of no where. So based on my situation, generally EFI is more sophisticated, efficient and effective. But carburetor is more wiser.

One benefit of EFI that you didn't mention is that in the event of a component failure, the ECU will display a failure code telling you what component has failed making it simple to fix the problem (if you have the spare component with you).

thanks for this video. thanks for the answer at previews video about injection, now i just buy injection motorbike

Great explanation on a great journey of why it must be fuel injection for world touring. Also i agree you should put a tank filter sock in tank to stop contaminates entering your tank. Keep up the great work you wise old sage!

Fuel injection all the way. I own bikes that have both and always gravitate to the fuel injected, and believe me I clean and maintain my carbs. I have yet to have fuel injector let me down. Can’t say the same for carburetors. Great stuff, Pavlin. Keep’em coming.👏🏻👏🏻

Thanks, Pavlin. Always trust you to come up with a counterintuitive and informative point of view.

I must admit that I am jealous that you have perfect weather and so many beautiful roads and places nearby. My next long trip should be to Bulgaria, I think. When it comes to today's topic, I'm not sure what I think. But to all of you who are looking for the perfect motorcycle, stop it! Take the one you have, service it and go now and do not wait for you to get too old or sick.

Question 1 yes Question 2 yes Question 3 yes Great video thsnks

Agree Fuel injection is the best !!

Have had both but I'm the carby-person. If carby is set-up properly, some high altitude is not a problem, will just lose some power aswell with EFI, EFI just burns petrol more properly. And if weight ALWAYS matters, I don't wanna carry a spare fuel pump. I instead would take a spare carburettor, not much different in price too :)

you don't need to be a mechanic to open a carburator or synchronize it. It's easy to learn. I think that if you plan on going on very long trips in remote parts of the world, it's necessary to have some mechanic skills on your bike (know how to disassemble parts, carburators, filter...)

Good video. Converted me to Fuel Injection... I still have Carburettor but next time...

Royal Enfield changed over to fuel injection on the Himalayan, solving a major short coming with the bike.

Back in the day when a vehicle stopped, short of running out of compression the first thing to check was the pionts, because that was the thing on the engine that moved the most now with efi the thing that moves the most is the fuel pump,

Re FI systems, if you have to change the fuel,pump you have to drain the tank. Unless you have something to pour the fuel into, or have extra fuel you have a problem, especially in remote locations. If you have a flat battery you can’t roll start an FI bike but you can push start a carb bike. If your battery is not at peak condition, it will spin the motor but will not have enough voltage to run the fuel pump. Speak to KTM owners (I am one) and you will find that many carry a spare fuel pump (500/690 owners) as they are a known problem area. Re altitude, Lyndon Poskitt says that the FI Dakar bikes lose power but not as badly as carb bikes.

Another glorious day in Bulgaria. I have always had carburettor bikes until this new one I have a VStrom 650xt. I'm looking forward to seeing the difference once we get out of this F£&###g lockdown. Keep on riding 😁😁👍🏍️

Great video Pavlin. I like the way you bring us along for a real nice ride AND tackle a popular talking point for riders! Always a pleasure to watch and listen!

nice vids IMO, if people want use the motorcycle extensive , Fuel Injector way to go, the saving on fuel consumption will pay itself the higher sparepart price like ECU, and all the sensors more optimize power and fuel consumption but not sure how long the manufacturer produce the ECU and the sensors in the future but if u just low milage in same period of time, the fuel saving not that much, when u have to replace much more expensive "electronic" and sensors etc :) my 1972 & 1981 150cc vespa and 1993 200cc Honda still using carb, and since i lve in SEA and all those 3 was single piston, and never ride higher than 3000M or on the snow, carbs still serve me well, other location might differ :) but i agree if people want to very long distance , better with FI (the power & fuel efficiency) and make full check which part near EOL maintenace before u go

I prefer injection, but the system require more than an injector and fuel pump to work. It use many sensors everywhere on the bike. Also modern carbs like lectron doesn’t have elevations and tune problems

I prefer injection systems, because they work in any altitude, don't clog over winter and don't need inspections. Anyway, my two (mild) Enduro bikes have carburettors, because they are older constructions. The most important thing for travelling is not carburation, but getting up from the sofa and start the journey ;-) Greeting from Nürnberg/Germany, Günter PS: Snow outside, I do envy your mild temperatures in Varna and being able to ride.

I agree with your arguments and I lean towards fuel injection. But I decided the next bike I buy will be a DR650 which is still carbureted. The reason? There is aftermarket fuel injection support! lol

No discussion: If I would be able to change on my old motorcycles from carburator to a retrofit injection system I would do it. Never ever I heard of problems of new motorcycles injection systems. In the beginning, yes, there have been some problems, I know, but these have been technical teething problems and nowadays the advantages predominates. As you said: altitude is a problem when you go over 2000 m altitude. That is the reason why Yamaha use on some Teneres carburators with an atmospharic compensation system (membrane based automatic pressure adjustment). Efficency and fuel consumption is also a topic. Very often I ride with a friend, he rides modern bike, I prefer old bikes. Both bikes have similar power but he always has injection systems in his bikes and I carburators. I always have a higher fuel consumption. One point is the fuel cut off in overrun mode, the other point is the accurate fuel injection a carburator never has. The difference is often more than one liter at the same route, riding together, same speed etc. etc. All your points are correct Pavlin, I agree in every point.

Good discussion, and I agree with your conclusion! Ride safe!

I think, as you say, this is not an issue for people who ride with new bikes anyway. I ride a 40 year old XL250 that i know inside out. I have considered, or at least would like to try a newer XT250 or KLX250 with injection, just to see if there is much difference on economy. 80mpg was always affordable.......but i hear an NC700 can do that too!

Hi Pavlin! On topic: Even Kawasaki gave up to carburetor when they lounched their new KLR 650 (I don't know if we're gonna see it in Europ even I hope so), They kept the simple construction, the single cylinder but they made it fuell injected. Of topic: Was that beer the tasty Burgasko? Big yaaammmmy if so ! 😊

that's why small planes have a mixture control lever to lean the petrol/air mixture, when climbing...

I always had carburators engines. But i wouldn't mind to have an efi engine at all. That being said i like the carburators power delivery. I consider myself on the %10 who can open and rebuild a carburator. Good video . Thanks

Im for EFI, but motorcycles that I like (90s) and that I can affored, usually don't have EFI.

Very useful video

The good about efi is that we can improve it by own by power commander etc.The bad is that efi is depends on electics and electonics of the bike.About carburetors,if we have good mechanic we could be very happy.

Absolutely for a adventure trip carbarator is very better than anjector. Sensor map. Ecu. Oxygen sensor abd........oni of thiy take minimum error motorcycle 🏍️ stopped. But in carbarator you can check that very simply.

Fantastic place Pavlin. I 💟 Carb.

Even Harley-Davidson made the switch to fuel injected 15 years ago. The trend definitely looks like fuel injection in the dirt bike market too. Unfortunately it's another reason driving up the cost for dirt bikes. I'm completely sold on fuel injection. Same bike for 19 years FI no problems yet. Probably just jinxed myself LOL My main riding partner has a carbureted bike, seems like that thing never runs right.

I 💟 Carburator. Saludos Pavlin desde Ciudad de México

@10:41 the people who say that never had the pleasure to take out and blow the clogged nozzles of a carburetor. And there's more than one, per carburetor :). Never had the pleasure myself but I know this from my father's old Dacia car, until he also fitted a "custom" filter to fix the issue. And god forbid if, while you're angry and tired on the side of the road, you manage to drop and loose those nozzles, as small as they are ...A small kit with spare nozzles should be mandatory for people who own carburated vehicles. As a side note, search for "Miss Shilling's orifice". It's an interesting story about carburetors :)

I have to visit Bulgaria 🇧🇬 one day, hopefully sooner than later 🤞🏻

The fueling in the F800GS is atrocious from the factory. It's like an on/off switch at low speed. The best fix I found was to wedge a piece of electrical wire in the throttle cam by the engine, effectively making me turn more throttle for the same power. Only works for cable theottle. It cost nothing and did far more than a computer to vary the AFR (although that helped some). I keep good mpg and throttle control, win win.

I am a mechanic and in my experience fuel injection on bikes very very rarely give trouble. The op’s “can you fix the carburettor yourself” is the actual real question. And the answer is generally, no you cant. So you will need a mechanic. Lots of times we have seen bikes and cars come in where people have tried to fix the carburettor and messed it up. As per what the Op says mid way through the vid. And mechanics around the world have been around FI for 20yrs so it’s not like they wont know how to fix it. (Only taking FI here, not ECU etc.). I ride an ‘08 BMW GSA with 366’000 kms on it. I carry a GS911 diagnostic unit. If it stops, I can diagnose the issue and order the parts it needs. So - if you have a bike with a carb, carry a carburettor rebuild kit. Get the mechanic to fix it. If you ride a FI bike, carry a diagnostic unit. Have fun.

Bloody nice mate

Carburetors suck, but fuel injection blows 😂

I totally agree with u that FI system is good. However, my lovely " Shisuka (Kawi 175 cc) " is 23 yr. old with carb system air cooled had more than 100,000 miles. Though I am an old fashion rider, I accept new technolgy but to change my old friend to find new one is not my concept. Just like a long married couples lived together for 20 yr. then new young girl who is beautiful fresh appears. Are you gonna replace your long time friend in exchange with new one ? New techology is good and better but in some case old technology suits old people.

Thanks for making these very informative videos.

That’s. great view at the start! Beautiful area.

Lucky for me I and some of my friends are those 10% that can fix and sinchronize a carb. So carb it is for me. But for all of my other friends which i know won't be able to fix or maintain a carb I highly suggest taking bikes with EFI, mostly so they don't bother me maintaining their bikes and wasting my time ))))) And really some bikes are better off with EFI, for example a 4 cylinder sport bike, the 4 carburetors are more likely to leak and 4 membranes are more likely to tear + it's a pain in the ass to take those carbs off those bikes. But on the other hand, a friend had a Yamaha R6 with carbs, sold it and bought a newer R6 with EFI, said that the old one with carbs was more fuel eficient and powerful... WTF... ))))

you are the best Pavlin thank you bro

Never had an issue with carbs but I grew up with em. Both have their merits and downfalls.

like these types of informative videos Pavlin.

Hi Pavlin, Bulgaria looks beautiful! Carb or injection, both good. Cheers from West Oz!

Walter Colebatch prefers EFI, because there are not so many failures, actually very little. And Lnydon Posskit prefers carburator.

Great points sir. Thank you.

amazing places , thanks for share !

I need to disagree with you on the manufacturer idea at the end. With fuel economy emissions are better on injection engines so unless the EU turns upside down, carburetors are not coming back any time soon.

Pavlin can you make a vídeo talking about what fuel /Gas use in long motorcycle trips? (Here in Portugal we have 95 Simple octane , 95 additives , 98 additives) Big fan of yours vídeo, thank you!

Very interesting approach, nice sea view. 👍

Thanks. If you want power with efficiency you go infection.

Yay! I'm into that 10%

Fuel injection is only to comply to emissions not for better "running" as your experience goes. Also all Dakar bikes which had varied elevations in South America, till the year 2015 were all carburated. Also, FI bikes running not losing power is a myth. Anything at altitude WILL LOSE POWER, because the formula calculating compression ratio for an engine is measured at 1 atmosphere which is 101325 pascal.

I had this conversation with a friend a few years back. We were planning a road trip across Canada. He was 100% for a Carburetor because of the potential to fix it on the go. My logic was and is that we wont be stranded "a million miles" from a dealer of Garage so it's not an issue. By the same token, if we had been planning the Road of Bones in Russia then yes, I would go with a Carburetor for those reasons. The reality for most riders is, the roads are ok, the Logistics are there and it comes down to the "FIVE P's" when all is said and done. Proper Planning Prevents Poor Performance. If you want to go with a Carburetor but, have never actually worked on one, do what I did for him. Go and buy a cheap old Lawnmower.... dont laugh, Carburetors are virtually identical no matter what they are on. Strip it, rebuild it and make your mistakes on something that is cheap and your life wont depend on in a crunch.

I'm afraid to say carburettors have had there day. As you've pointed out if you are able to fix a carb, you need a very clean area to do it. Any spots of dirt will block the jets you've just cleaned.

It is not possible to meet Euro 5 emission standards with carburetors. Basic design of carburetor gives ideal air fuel mixture in engine rpm midranges. But it is rich at low rpms and lean at high rpms. More complicated mechanism is needed to maintain ideal mixture at all rpms, but that will the carburetor too expensive and still to keep air fuel as precise as in fuel injection system. Another item to keep in mind is that in non-turbocharged engines, air is drawn by piston moving down regardless of carburetor or FE. Your carburated bikes were malfunctioning at high altitude because the thin air mixed with same quantity of fuel delivered by carburetor jet making the mixture very rich (like driving with choke on). This rich mixture reduced engine power. Your Benelli with FE sensed the thinner air and reduced fuel flow and leaned the engine to maintain optimum output. Third, you can only adjust idle rpm or idle mixture at high altitude on a carbureted bike with screws. You have to replace jets with smaller jets if you are actually living at the high altitude.

There are upgraded carburetors which will not require tuning and its plug and play systems...its also on youtube.

one thing you did not cover is the cost of modifying fuel injection as you have an expensive power commander module to make your fuel injection run properly with your aftermarket exhaust, power commander here in australia costs around $500 + then usually needs a dyno to make it run in tune add $800 .A carburettor jet only costs $8 and can be changed with little effort.of course if you leave your bike standard this is not a problem but over here nobody does.I sold my xt660r last year which i did love and now have the dr650 and am enjoying riding a much lighter machine.

Yamaha xt660z tenere very good

Very nice video but one thing I do not agree with is "if people need it, the market will make it". It is sadly mostly a rotten way around it (doesn't matter what market): you do not need it, but the manufacturers will make it so that you will be forced to need it (they create the need for it) and you will buy it.

Why do you have such fine weather in Varna while we have rain and cold here in Bathe-Wurttemberg? 😉 Enjoy it!

Hi Pavlin, what do you think, is the new Ténéré 700 suitable for 2 riders + luggage ( cca 200kg) ? Thank you in advance, keep up the good work 🤜🤛

I'm jealous!

Still considering what grownup bike I’m going to get when covid allows driving tests again in Britain... I’m considering your bike, but no one here sells them because I guess they know the value of them, the Tenere 700 (I can finance it but it’s a lot more expensive) and finally a drz400... which is a carb bike... but stay with me - it weighs a third less and is practically indestructible... so after your video I’m still no nearer knowing what I’m going to get...

Injectors in my opinion gives a more stability works,more cilinder-more stability

Unfortunately, in French, Phoque means Seal...

Dunlap mutant tire review ,near future ?

Interesting topic you raise Pavlin. This has to be one topic I have to disagree with you. Number one point is fuel injection on engines now is to make them pass emissions laws along with catalytic converters, injection is more efficient for sure but they do run run them very lean to do so. Number 2 is carbs are a very simple unit, when people take about repair carb, what do they mean ? There is not that much if anything that can go wrong, if you set up the carb before you go on a trip, jet it properly and check the needle and needle jet for wear and set that correctly, you should never have to take it off again. Dirty fuel can be an issue but run an inline filter and carry a spare, they are not big. Number 3 the biggest problem with fuel injection on bikes or cars is not always the injectors or the pump but the sensors, air temp sensors, water temp sensors, air density sensors and so on, not all mechanics have access to the technology to find out which sensor is faulty, fuel injection is more efficient because the ECU relies on the information from the sensors to deliver the correct amount of fuel, if one link in the chain breaks the system fails. A carb relies on basic physics, gravity is always there. There is an old saying if you can’t fix it with a hammer, it is electrical. I have had bad experiences with injection that I could not fix without the aid of a laptop, only problem I have had with a carb was, apart from dirty fuel, when the needle started wearing and the engine started running rich but that was 320,000 Klm’s and it cost $25 and 20 minutes to repair. Like most things learn before you go, not on the road, same goes for fixing flat tyres, tubed or tubeless, no god trying to learn at the side of the road, too late then. Like you always say Pavlin preparation is the key. 👍👍👍👍👍👍👍👍

So the cathalitic convertor is a must have on a bike, because every new bike has one? I'm asking for a friend...
