Fixing the CB650R's Power Problem 

One or two more mods and this bike will be finished, if you want to help pick them join the discord through yammienoob.co/

It's not making more power because your AFRs are out of wack and likely everything else too. More rich means cooler engine but it also means you are leaving a ton of power on the table by doing so in many ways. Tuning is about finding the balance for the application. The reason factory bikes are tuned so lean is emissions. The leaner/hotter the engine runs(to a point) the more efficient it will burn the gas. You really should go find a tuner in your area and have a comparison between factory, OTS(off the shelf, what you used here) and custom tune. Also talk to the tuners about the issues with out of wack AFRs either rich or lean. Both too lean and rich have issues, lean is just more scary cause of higher heat. And there's so much more than just AFRs, that's just 1 part of the tune. Also I do not recommend anyone pickup a custom tune from someone else. These tunes are precise to not just the bike but the fuel and atmosphere it'll be used. An aggressive tune from a east coast person with 93 octane at sea level is going to grenade your bike if you live in Colorado and take it up 8,000ft with 91 octane cause the tuner didn't make the tune for that. While I applaud the sharing, be very careful using custom tunes. Hell, be careful using any tune and be aware of what the tune will do and how to best ride it, bike or car.

Buys a Busa then every video for the next month will be "Fixing the XXX's power problem"

More power, as Pumphrey says: MO POWA BABEH!!

Just a quick comment to say keep up the great work. Love your videos and you (as well as some other RU-vidrs) motivated me into getting a bike which ive had for a year in April and now I'm in a Motorcycle Club! Hope you have a great day Yammie! ❤️ Love the vids.

Can you do a bigginer set up? Like a tutorial of what gear to buy in 2020. Do like a "all the gear you need for under 1000$ in 2020"

great timing guys!! thanks! My CB650R is ordered and coming in a week or two :D

I got a 2018 cb650f for my first bike. Came with the power commander 5 on it. I love it.

That bike is perfect, almost too perfect....

i thought i only "liked" you guys... but then i realized i freaking LOVE YOU guys.

Riding this bike for some time now. Don’t feel any power dip. It’s indeed linear without surprise and from 8000 to 12000 the stock version is already crazy. As well I wouldn’t change the exhaust. The stock version looks sooo good and the sound is great without blasting your ears. Otherwise, indeed convenient to be able to try different setups. On my KTM I had a switch installed, after some time I always kept the same setup. On this HONDA there is only one thing you must change right away: the tail! Have fun!

My second bike by far was the loudest thing I’ve ever heard. Magna 750 V4 straight piped. That thing was absolutely loud all the time. Idle “BWAAAAAAH”, cruising “BWAAAAAAAAAAAAH”, WOT “BWAAAAAAH, BWAAAAAAAAAAAAAAH, BWAAAAAAAAAAAAAAAAAAAAAAAH”

I think this video just made me seriously consider buying this bike

Just in case that happens AFTER you install the full system. Before that it works perfectly no dips. I'm working my way around it as we speak. I installed an Akra full system this weekend no DB and I felt the dip..

Have you announced when the next bike giveaway will be? I looked on patreon but could not find a date.

Going too rich will also dilute oil at the piston rings meaning you are more likely to suffer from bore scoring.

Your choice of music and the "hands" remarks at the end seem to confirm my suspicion that you are an accomplished fellow pianist. Any truth to that?

Had to do something similar for my 390 Duke because it runs a bit lean by default and it can be a bit jerky. Also auto-adapts to any of the popular mods to the bike (exhaust, air box lid).

Too rich can wash the walls of the cylinder and you can get premature ring failure and gas soaked oil. I've seen this happen on a car and eat the rings pretty quickly.

"Doin some danger to manifold shit over here fast & furious style".... Hahahahaha

You two have some of the best recorded Bluetooth intercom conversation. Any chance of a video explaining your setup?

My Harley has a Vison Commander mounted on the handle bars. I can adjust the tune while driving and see, battery voltage, tps, engine temp, a/f ratio, rpms. I have only seen these for harleys. Do they Make it for the Jap bikes, so you can adjust it w/o a laptop.

Hello ,great work in the Chanel ,want ask u something, dinojet powercommander have a map for leovinci exaust our you tune manually?I have a ixrace mk2 and there no map for that exaust .

Imma be getting my first bike within the next few weeks .... I got approved waiting for the financing papers to get here to sign em n send em back out

Power commander 5 and the autotune. The autotune adjusts your fuel air ratio in the fly lol

hey fammie doob - better slow down on those twisties - think of the young yams - we don't want to lose you to crazy riding

Cool video Yammie, do you think that power command!er would work on a cbr500r. I dont need the extra power but want the enigine braking to be a little more relaxed, it kinda over brakes when engine braking, almost like you braking kinda hard when it kicks in or any time you off the trottle

Not only will running too rich change the smell of the exhaust, but removing the cat and installing a new exhaust will change the smell, since there won't be any unburnt combustion gases when you have a cat installed. It's a good thing to install a higher flow air filter when you put on a free flowing exhaust, as your engine is nothing more than an air pump, and the more air that flows through will increase your power. You aren't going to make much more, but it will be noticeable.

The video suggests a rich condition across the low and mid rpm ranges. So my question is, did you guys determine this to be true, and did you go back into the PCV to dial back the fuel mixture? Dynojet has a fuel controller, PCFC, for the CB650F, 2014-2018, that uses the same map tunes as the PCV. I have a 2018 CB650F. I purchased the PCFC, and downloaded the same tune you guys did. I installed a full Yoshimura R-77 which I think is pretty close. One of the features of the fuel controller is being able to dial in/out fuel in 10% increments at each of the rpm ranges. Not installed yet but will soon.

In their mind: i mean, what could go wrong? Also them: f@&k it, we spent over 4 hour figuring things out

My best mods are 20mm lower footpegs and 20 mm taller handlebar....and a tailtidy! And heated grips..and Motogadget glassless barend mirrors

Alrighty bois. I wasn't sure if I should get a SV650 or CB650R for my first bike, and after watching numerous videos on this gorgeous gal, you've sold me.

Just bought this girl yesterday my first bike lol. Gonna drive like a granny probably for the first year but my brother took it for a ride said it was surprisingly fast as Hell 😂😂 now I'm a bit nervous.. just take it easy i guess I'm in no hurry to do whoolies.

Are the maps available free for or do you have to pay extra for each map???

If the bike has a PAIR valve in the emissions system it could also creating popping noise by injecting fresh air to the exhaust to give lower emissions. My VTX 1800 had/ has this.

I have a CB650F, which is a great bike and practically identical to the 650R. It's definitely an underrated bike and I have yet to see another one on the road. But besides that, the engine doesn't really have a lot of extra power to unlock over what it comes with stock. One thing you can do to recover power being lost to incomplete combustion is to side-gap the plugs. This is an old school tweak that goes back to the 60s, but it works very well on bikes and if you are using iridium plugs you will not wear them out - whereas the old copper plugs of the 60s would wear out much quicker when side-gapped. Just by doing this you will smooth out the engine throughout the rev range because side-gapping increases the immediate surface area of the electrode exposed to the fuel mixture. The process to do this is simple. You remove the plugs, and you use a hack saw to cut the ground electrode (the one that you would normally bend to adjust the gap) slightly, so that when you view the plug directly from the top down, you can see the positive electrode. This cut needs to be straight, and the edge of the electrode needs to be free of burrs but as sharp of a 90 degree angle as you can get. You then have to adjust the gap using the bottom corner of the negative electrode that you just cut, so that it is 0.030" (the universal gap that works the best for almost all applications) between the edge of the cut electrodes' bottom corner and the top of the positive electrode. If you do this correctly, the spark will not be fully exposed to the fuel mixture, whereas before the negative electrode would obstruct it. The obstruction does interfere with combustion and it reduces the percentage of fuel that can be burnt with each firing of the plug. By side-gapping the plugs, a higher percentage of fuel is burnt, resulting in smoother engine at all RPMs and improved power. This works on any vehicle that uses spark plugs. If you do not want to modify your plugs, Bosch makes "Platinum +2" and "Platinum +4" plugs that are effectively side-gapped from the factory and might fit some bikes; just make sure to verify that the gaps are 0.030".

Is there even a date to when the giveaway bikes are gunna be given away?

I have been riding for over 30 years on the street and I want that bike! It would be my choice for a second bike.

You guys :) The best

If you would live in europe(Austria) where you can ride in the alps, would you recommend the MT/FZ07 or the Cb650r. I am not sure which bike i want to buy. The price is literally the same on both bikes. Any suggestions?

Such a great Bike. I would argue its the best in its category. It destroys the mt-07 and others in every component, comfort, rideability, suspension and worth the little bit of price difference. It can even go to blows some bigger CC Naked bikes but with the bigger bikes its also obviously rider skill. Honda make a masterpiece with this model. But thats my opinion and of course other people prefer different things out of a bike.

When you talk with your hands while riding I'm always afraid the cars in front are going to think you are making some kind of rude gestures towards them.

Thanks for this

A few things. I'm a light load situation a leaner mixture burns much slower which is why very light load tables have a lot of ignition advance (30-40+ degrees of advance) so the combustion event can finish closer to top dead center of that cylinder. When you lean a cell at light load you can get burble/pops on decel because it's actually a misfire where most of the combustion is trying to happen after the piston is closer bottom dead center. You can increase the intensity of the burble/pops by leaving the fuel where it is and retarding the ignition timing. You can go as far as triggering an ignition event when the cylinder is on the exhaust stroke with the exhaust valve open. You can get some serious flames and bangs that will have the police called because it sounds like gun shots. You can overheat the exhaust valves and damage the exhaust from too much of that. A setting like this is referred to as anti lag for a turbocharger.

Hey buddy which map are you using on the map because on the website only 5 are mentioned which one did you choose? I have installed mivv mk3 on my bike but couldn't find a map for it so what should be done for it? Should i get a autotune or just use Akrapovic, Arrow and Tbr maps and see how the bike reacts to it?

You just made a perfect bike, imperfect!

I need the intro song and that ninja 400 🔥

propping the gas tank up at an angle: I dunno about the CB650R, but that is actually the suggested method for simple maintenance in the Service Manual for my old Katana. That comes from Suzuki. ain't no one complaining about that.

So straightforward any computer science graduate student could grasp it easily.

Don’t sweat propping the tank up for simple service stuff like this. The factory service manual tells you to do it in most cases. GSXR manuals say you can do the whole valve adjustment with just a tank propped up. Some GSXR’s even came from the factory with a tank prop stored in the tail section with the tool kit. I can’t speak for kaws or Yamahas since I don’t work at a dealership that sells those.

Trading in my CBR300R for a 2018 leftover CB650R black. Gorgeous, comfortable, fast bike.

trying to find a power commander or something like it for my year 2000 honda valkyrie and im having trouble, any suggestions?

Hi, I just got a PC5 for this exact bike but I could not find the specific map for the aftermarket exhaust . What I can do for get it tuned correctly ? Please advise. Thanks

Had a dip at 4500 rpm on my 94 cb1000. I added a 3° timing advancer... problem solved! Not sure how the timing works on the new bikes, but you should definitely try that too. You’ll have to run 91 octane, but so worth it!

Which model of power powercommander did you use? The one available for the cb650F ?

I have missed so much from your videos (timeline).... but no longer 👍

Hey guys I have a 2018 Honda CBR 650 F I just put the power commander on... Also a k&n air filter and a hotbodies full exhaust system... It doesn't have a map for my set up... Should I just pick any map with an exhaust and a high flow air filter or should I go get it dyno tuned and dialed in?

Never fails there's always some guy on a ride that needs to go to the gas station for a fill up of gas.

To have it less Ritch. Do the airbox mods. More air = better explosion and less unburn gaz. Better economy and more power...

Can you compare the remapped CB650R vs the GSX S750?

can this apply on 35kw version if i change the air filter and air flow to engine ? I want 70kw but in paper 35kw u know :d

I have one question I am going to buy a AKr full exhaust for my cbr650, do I need to buy an optional catalytic converter for the full exhaust? I am not planning buy a PCV for my bike, maybe I can just use catalytic converter instead of PCV?? please help

When I have all the connections apart, I like to dielectric grease them all...

Could I do the same thing to my 98 900R? Or is a power commander only for fuel injection?

is there one of those Dyna things for my 2013' Stryker 1300cc?

Running too rich causes oil deterioration, piston rings do not seal 100%, unburnt fuel will pass by the piston rings into the crankcase a dilute the engine oil, which can lead to engine damage, keep an eye on the oil level and smell, This all was a bit of fit and hope for the best, this really should only be done with a wide and to get AFR readings

My dudes go triple up! Yam,J,and the steady caressing hand of god! Then Install an A/F logging software or J on the back with the netbook. It should read 11 or 12 at WOT and 14 at full roll. We don't want to guzzle 10mpg. Ride to live live to Busa!

Hey fellas! Thw power commander specific to the CB650r? I only ask because I checked on dynajets website and they dont appear to have it for the 650r.

Too rich fuel mixture will also cause carbon build up in cylinder head. Which means after a while your valves and valve seats will be contaminated causing bad seal and resulting in compression loss. A good advice to always keep your engine running on optimal fuel mixture :)

Those new bike with o2 sensor if install aftermarket full exhaust you dont really need to install pcv the bike run good without the ECU will adjust automatically thats why there is O2 sensor there........and if you really want more hp just reflash ECU .

I am having trouble navigating the tunes. Which cb650r tune did you use?

I like big bike.and. I love ride and travels.i know one day I will have that too.

(old school two strokes that have ridiculous powerbands and can be dialled to an even crazier level with something as simple as an expansion chamber) - *Don't mind me, casually brapping by...*

Doesnt a too rich of a mixture degreases your engine ?

Why power commander when you could get the ECU flashed/tuned?

Put it on a dyno and maintain a 14:7 AFR through the rev range. I would put Evans nano glycol in the cooling system which means dumping any water based coolant. There is so much you guys have touched on which shows up the crazy state of play that people have with respect to running an engine lean.

Easier way for the tank rather than prop it w a hammer. Get a cheap strap w coated hooks. Run it to the grab bar and to the front of the tank. So much easier 2 work with

Oh so your a Wildcat fan with all that knowledge lol to this day I've been looking for a shark eating a cheeseburger

Mo powah baby

incidentally the dynojet website does mention that the PC5 "fits" 2019 CBR650R and the CB650. will they do so if the controller wasn't meant to be used with the new bikes as someone mentioned here...?

IMO this is the best looking bike in your garage

Rip missed out on the one up five down shirt

where the heck did you get a power commander 5 for the cb650r? i cant find one even on there page.

Everything needs power when you have a Busa... yup

Placebo effects in medicine suggest purely that there is a perceived benefit when no objective measurable impact for curing a disease can be scientifically measured and or observed. In the case of motorcycle tuning-if the customer perceives a desireable result of power-however-slight-then satisfaction is achieved. If this tune does nothing more than aid in a more linear power delivery without being significantly more powerful in any meaningful metric-the perceived value proposition is still a net positive.

Sad that no dyno include than we can see preciselly where new map is better than old ,stock cb 650 r dont have huge hole on power graph bigest at 6 k rpm but its nothing compare to me last bike cb 500 pc26 🫣 hole in this bike between 5 to 6 k rpm is huuuuge and you can fell this only when you do test on 1 gear from low to high rpm 👌🏻 Dyno also show huge hole there ,this was one of reason why i sell this bike 👌🏻 😁

So I'm very confused.. I've just been looking on Dynojets website and there isn't a Power Commander that fits the CB650R... I couldn't even find the one that fits the CBR that you mentioned in the video. When I enter the model name, year and so on the CB650R doesn't come up as on option. What's the dealio?

I've got the 2017 650F And it's restricted.. would It be the same process?

Mo Powah Babeh!

Do you know if the 2020 has the same dead spot in throttle?

So, with both the CB & CBR 650R having essentially the same engine, IF I got a CBR650R LAMS/A2 Restricted bike & wanted to de-restrict it, could I install a Power Commander V instead of getting the stock ECU Flash Tuned & Dynod? I mean, if the Power Commander bypasses the ECU & inputs its own Tune, then it would stand to reason to my way of thinking that this would be doable, yes? Also, do you have any idea as to whether a pipe like you have on the CB650R in this Video would be Legal in Australia? Like, having a full pipe with no Cat or Muffler/Noize Restriction/Sound Dampening? My personal thought is the noise factor would be a non-issue considering how loud some Harleys can be, or aftermarket car exhausts, etc... my main concern would be the lack of a Catalytic Converter making the bike non-roadworthy in NSW, Aus. ??? Thanks guys!!

is this a good beginner bike for first timer riders???

How I wish I have a bike like that.. My dream bike..

Arizona has strict emissions testing. Will this pass emissions?

The red is looking gorgeous in your videos, however I think I'm leaning to the black if I do choose this bike this spring. Anyone got any thoughts on red or black in the flesh?

It's an old video ik. But I really wanna know ahah - Is it necessary to change the fuel map with a slip-on exhaust?

What? Honda don't give you a tank prop like my Suzuki SV650S has? More reason to love my Suzi :D

Anyone know the name of this song? 7:27

Pls try flattrack my dude

This video demonstrates the worst way to get more power out of that bike. The correct answer is the CB1000R
