Carburetors get gunked up as they sit unused with fuel in them. The fuel starts to separate, and the newer ethanol-mix gasoline separates faster than older gas ever did. It is simple, but time consuming to clean your carburetors. Even though it is simple, care should still be taken while performing this. Keep carburetor cleaner away from any rubber or plastic parts, and follow the instructions laid out in this video.

dosnt matter that you say somthing wrong, the fact that you made the vid, to help folks makes you a hero in my book

@rickpope5388 6 лет назад

One of the best instructional videos I’ve ever seen. Thank you.

@hazennelson4057 3 года назад

Might be an old video but SUPER useful I just bought a 99 Banshee with a 93 FZR motor. Pulled the carb off this morning and rebuilt while watching this!

@leighmuldowney4380 5 лет назад

Bro your a boss ive had starting issues on my fzr for months and this has literally saved me £££. 👊👊

There are also passageways inside the carburetors that get gunked up. I hate to say this, but pull them off again, take the jets out, and do the same thing with the guitar string inside the carburetors. Then spray through the passages with carburetor and see if a stream comes out. The passages go through to the carbs and out the air filter side. Clean from both sides with the string. Also I would pull out your air/fuel adjuster screws, clean them, and set them to the factory number of turns.

@LegitRaceCraft 11 лет назад

The fuel economy problems in carbureted bikes almost always lies in the spark or the carburetors. You should check your spark gap first on your spark plugs and if your coils are still providing a hot spark (resistance check on the coils, the repair manual describes how to do this). That is the easiest thing to begin with and rule out. Then clean the carburetors well. If done correctly it should run great after that.

Your mystery tube at 43:00 on the California float bowls was where they were hooked up to the charcoal canister for the gas tank vent. Originally there would have been a tee fitting between them and a line going to the charcoal canister which has a line going to the gas tank.

@macmorgan6685 Месяц назад

Actually, the “cheap” screwdrivers supplied in most Japanese mc tool kits are JIS, and they do work much better in those carburetors. I’ve been working on these bikes since my first Yamaha YS1 250. I know about caming out the screw heads! You’ve been lucky… btw, I also have one of those T handled screw drivers! You can order the handle and the JIS blades from any site with Honda or Yamaha parts.😂

@cyrielgaemers 3 года назад

I want to thank you, I learned a lot from you!

@LegitRaceCraft 3 года назад

You're very welcome!

@LegitRaceCraft 11 лет назад

I've seen it both ways. Sometimes it is still good and sometimes it leaks air. I've sealed them up before with RTV silicone from napa. It doesn't look pretty but it fixes it, plus it ran fine for 3 years. If you don't have idle problems then you should be able to leave it like that and it will run fine until the cracks get worse.

@alexgleason3578 3 года назад

Great video, thank you sir

@LegitRaceCraft 12 лет назад

you will need the same one. You can probably order the screw online at shspowersports, just navigate to your motorcycle and go to the carburetor section to find the part on the diagram.

@LegitRaceCraft 11 лет назад

that sounds like a throttle cable issue. If your cables are too tight on the cable adjuster then they will stick for sure. It is common when you are putting the carburetors back in to overtighten them. I've done it before. Also when the front wheels are turned, if the throttle cables aren't routed the correct way it will put stress on them and possibly shut off the bike. Check the cable routing and tightness, maybe even spray some kind of silicone lubricant inside the cables.

@LegitRaceCraft 12 лет назад

That's a pretty common thing. Sometimes they don't slip back because they get a little dry, you can wipe a little motor oil around it with your finger to lubricate it then it should pop back in. Or if your hands are clean enough you can spit on the tip of your finger and wipe it around.

@LegitRaceCraft 11 лет назад

yeah. all the choke does is change the air/fuel ratio for starting. So adjusting the air/fuel ratio should fix it. Those little o-rings do get stuck quite often.

@kalvinkorff9221 5 лет назад

this guy takes his fucking time oh my word

@LegitRaceCraft 11 лет назад

string size will be either .010 or 10 gauge, which is the high E string. That size works on most carburetors. I've had to get .009 before for carburetors on a 250.

@Aapo1495 8 лет назад

Got a little help from this video, thanks mate

@LegitRaceCraft 11 лет назад

slides are driven by vacuum only. They shouldn't open when you move the throttle unless the bike is on and there is vacuum from the engine.

@LegitRaceCraft 11 лет назад

I think it is talking about a fuel level meter, I'm not exactly sure what it's called. It's like a little tube thing with a hose on the other end that you connect to the drain plug. The fuel level should go up to the 18.5 mm mark on the tube. I've never had to use one on the floats because I haven't encountered a float height issue.

@Plainpat94 9 лет назад

you get off task very easily!

@LegitRaceCraft 9 лет назад

haha..that's a problem I'm aware of and working on. I've tried doing a script but I forget to write steps down and get thrown off.

@LegitRaceCraft 11 лет назад

Most of the time when they sit for a while then you need your carbs cleaned. I'm not sure I know what you are describing with the fuel-filter-looking thing on what is as small as a coolant line. I'm not familiar with anything like that on the FZR. A fuel line wouldn't be that small unless it is a very small engine. It could be the vacuum line for the fuel petcock on the gas tank, but I don't know what the filter-looking thing is. A one way check valve maybe? There is no reason to have one there

@rg10969 11 лет назад

I think my problem might be on each of the idle/mixture passages. I removed the screw but I didn't see the little o ring and figured it was down in the passage. So I didn't spray out that passage with carb cleaner (didn't want to swell the rubber o-ring), after reading on FZR Archives I think this may be my problem.

@dkruitz 5 лет назад

JIS screwdrivers are better - no doubt about it - you've been lucky with the Phillips bit so far. Seriously use metric tools on metric fasteners! The flat blade screwdriver mod is good.

@F355gtsBerlinetta 11 лет назад

Hi, My slides don't move when I open the throttle, what is wrong? Or they only slide when the engine is already running?

@bugzie706 4 года назад

only when running or you would have to have 4 cables going to your throttle

@LegitRaceCraft 11 лет назад

there is a video on that..and a link in the video that leads you there :)

@ALEXELY925 11 лет назад

Thank you for making this video it was super helpful!!! The only question I have is what are the other adjustable screws? They are next to the fuel/air mixture screws, I think one on each carb..

@jaredbennett7903 9 лет назад

I just bought a fzr 600 for 250 and it was setting up for three years I took the tank off and the and it was rusted and still had fuel in it but luckily the guy had a cut off valve and the fuel filter was clean so do u think if I jus clean the carbs and Chang oil it should be good to start

@miller6269 3 года назад

Thanks, you go slow and you show where the pieces go

@windtalker13420 4 года назад

Hey what is the other carb that you said you had on your fzr600 a 04 yzf carb or something but how did you get it to work in really wanting to try and do that and I cant find the video you was talking about please I need help with that if you can help please let me know my carbs are all screwed up from the previous owners and I can find any where to buy new carbs for this bike and I kinda would like to have a slightly bigger carb if possible its a 1994 Yamaha fzr600 not the cali one just the normal one

@dalancabo1995 6 лет назад

Hey man, I really need some help. I am currently working on my 91 fzr 600, and on the carbs you see those 2 hoses that are in between the 1-2nd, then 3rd-4th carb attached to the plastic piece? I just pulled mine off an noticed that they didn't have a hose on them and were just freely open. Where do they attach to on the bike? Could that be the reason it won't start up well? A vacuum problem maybe? Please help.

@LegitRaceCraft 6 лет назад

+dalancabo1995 the hoses are for fuel overflow. It will function fine without them. Mine didn't connect to anything. I've heard that on racebikes the overflow tubes fed into a canister, but the canisters never came on the models that were sold to the public.

@rg10969 11 лет назад

Thanks for getting back, I used the guitar string and completely went through the carbs. I got it all back together but my FZR won't stay running unless I have the choke on. Any ideas what might cause this? The bike hasn't ran since last summer.

@rg10969 11 лет назад

I was wondering if you know what would make my throttle stick and not return to idle sometimes. Also sometimes when I turn the wheel it kills the engine. I also have 91 FZR, doesn't look near as nice as yours, I would love to do the R6 tail swap but lack of funds now, so I still have original tail.

@Jeweltocool 5 месяцев назад

Can someone tell me what the parts called that goes inbetween the 2 bowls it’s like a yellow 2 to one connection point with a hose coneected to it?

@LegitRaceCraft 5 месяцев назад

Look up a parts diagram like the one below, I'm not sure what part exactly you're talking about since number 45 and number 47 on this link fit your description. www.firstclassmotorcycles.com.au/partFinder/fiche/yamaha/1992/fzr600/carburetor

@dannygdl86 12 лет назад

Hey how u doing.... Need ur help, i got stuck in putting back my floaters. I think the rubber gaskets got bigger.. is hard to put it back. Do i need another one? Can i use any other house hold gasket??? Wanna ride this bike been two years with out it...

@darrellw82 12 лет назад

Pretty sure my fzr600 needs this

@ALEXELY925 11 лет назад

now im having a new problem, my fzr ran great for 10-15 mins after i put the cleaned carbs back in, but just now i rode it to work and it sounds like its running out of gas (which its not). im really confused now... im thinking maybe somehow the fuel line got pinched ill take a look at it tomorrow. it just sounds/feels like its not getting enough gas. any ideas?

@F355gtsBerlinetta 11 лет назад

Thx! My bike has been sitting for a long time and now it starts very diificult and when it finally starts it is running with low rpm,s with a fully open throttle. What is your opinion? Clean carbs? Vacuum leak? Or what? B.T.W I have a hose that is left over which has something that looks like a fuelfilter in it but than totally black and the hose is about 50 cm. long and about the thickness of the hose that goes to the coolant reservoir? Any idea what I mean or where it belongs? :-)

@househowes 11 лет назад

my lower carb boots r showing cracks but when I look on the inside there clean possible to have a slight leak there?

@whazuup000 11 лет назад

how do I measure the height of the floats I have a yzf r6 and the manual says 18.5 mm but the floats don't even get any were close to that before the float toches the top part near the base were its screwed on. appreciate if you can help me out been trying to get it fixed for months now.

@Simon-bu4kc 5 лет назад

nice detailed instructions man but geeez, it was hard falling not asleep xD at least in my opinion you could speed up about double in explaining stuff and it would still be great content and easy to follow step by step. I mean 25mins video should have been enough ;)

@andrewmunz1639 8 лет назад

JIS. IS THAT POSIDRIVE or philips,,,,right tool for the job

@streetlimitz89 10 лет назад

I bought n fzr600 for 200$ guy said it wouldn't get spark.... I took the kickstand switch off and she fires up but dosent like to idle what could cause that its also seemjg to be running VERY rich. Its shooting flame around 3500 rpms and do sent really wanna go over 4500 rpms

@LegitRaceCraft 10 лет назад

if it is running rich then have your carburetors cleaned and adjusted.

@joshk7928 11 лет назад

Hi there I have a 1993 fzr600 and on a full tank am only getting 147ks or about 27 mpg before i need to switch to reserve. This is far low for the specs on fuel economy on websites. Would you know a solution for me, cheers in advance :)

@steezridin6974 6 лет назад

At 24:40 when you say the fatter jet is the one inline with the screw, you mean the one with the fatter hole in it right? Cause mine look exactly the same. Is this one (on the left, inline) the main or the pilot jet?

@steezridin6974 6 лет назад

When I say they look exactly the same I mean on the outside. I have four with bigger holes and four with smaller ones as I believe I should

@LegitRaceCraft 6 лет назад

+steezridin yeah, I meant the one with the larger hole inside. That is called the needle jet or main jet and it sits inline with the screw that holds down the emulsion tube. If you look inside where the jet goes you should be able to see through to where the needle sits when the diaphragm side is installed

@steezridin6974 6 лет назад

HourNine Racecraft awesome thanks so much for replying man! I have another quick question about something I don't believe you covered: when putting the float needles back on the floats, does it matter which side the metal hanger on the needle faces? It's kind of an L shape and I'm not sure if the two circles that would create the bottom of the L should face downwards or upwards?

@LegitRaceCraft 6 лет назад

+steezridin no..it can go either way, but just make sure the needle moves up and down when the float does. Otherwise you'll flood out the carbs or not get enough gas. The most import thing is that the needles are clean and the point isn't worn out on the bottom

@steezridin6974 6 лет назад

HourNine Racecraft sweet thanks for your help man!! I was googling these things for hours and couldn't get straight answers so I really appreciate it!

@lucasryman5175 3 года назад

which size main jets are used?

@LegitRaceCraft 3 года назад

I don't remember, it's been quite a while since I had this bike

@andrewmunz1639 8 лет назад

hey dude i finaly got my carbs off, i followed your vid,as far as possible but i have a problem,,,i have removed and cleaned the jets but the third hole,,,,what is it, it seems to be blocked.pressed in?

@LegitRaceCraft 8 лет назад

+andrew munslow I don't remember if that particular jet is removable or not. If you can't remove it, you can always remove the emulsion tube (the thing that holds all of the jets). You can remove it by taking the capped-nut off of the top (approx. 6mm size), then it should slide up. After it's off you should be able to clean both sides of the jet as I showed in the video. Hope this helps! I haven't worked on a set of FZR carbs in a few years.

@rg10969 11 лет назад

Hey Match, Do you know what size guitar string you use in the video?

@jaredbennett7903 9 лет назад

And the guy parked it be cause the push button start went out on him any ideas on how to fix it if that is it I have not had a chance to hook battery to it yet and the button is a lil stiff but still moves

@sudoggyhs 8 лет назад

I'm working a fzr as well and what I did is pretty much cleaned out all the all the electronics. like the turn signals the digital tuner the relay and rectifier in the back of the back imma try to put a video of it soon and what tools you will need.

@streetlimitz89 10 лет назад

I just got a fzr600 for 200 and it runs I found tho that there is a tube that comes off the crank case near the transmission and it blows oil out what is y and where does it hook to?

@LegitRaceCraft 10 лет назад

it is the crankcase ventilation, and the hose that goes up to the bottom side of the airbox. If you don't have an airbox, then get a little breather filter from your local autoparts store.

@KbBeBallin45 9 лет назад

How do you get that top half of the engine where the carbs are off? I'm having trouble getting that off just to start the carb cleaning

@LegitRaceCraft 9 лет назад

KbBeBallin45 Remove the gas tank cover, and then remove the little metal gas tank. You will have to remove a few rubber lines. Then take an allen key (hex key) and loosen the clamps. Take off the throttle cables. It should take a little force, but they should come out. Getting them to go back in is a little more difficult since they are hard to slide back in the boots.

@markgonzalez5032 7 лет назад

can somebody please tell me whats the worst that could happen if you don't have one of those tiny o rings on the diaphragm side?

@paintherapy666 7 лет назад

Mark Gonzalez Probably won't seal and suck properly

@paintherapy666 7 лет назад

Actually he said it's for the choke

@jaredbennett7903 9 лет назад

I need help my screws are not coming out at all and I have a t handle

@LegitRaceCraft 9 лет назад

Try getting some vicegrips and clamping onto the side of the head of the screw, spray it with some PB Blaster before you do. If that doesn't work then buy a set of Craftsman screw removers, drill a tiny hole in the head of the screw with a regular drill bit (about 1/8) and don't go deeper than the thickness of the head, then switch to the screw remover (it's like a reverse drill bit). Apply pressure and the screw will either come out or the head will snap off. Once the head snaps off, the threaded part of the screw should come out easy. I've done this many times if the vicegrip didn't loosen it. Threads don't get damaged and the screw always comes out.

@pantherax1 10 лет назад

I HAVE A PROBLEM WITH MY FZR THE PREVIOUS OWNER BROKE THE SPARK PLUG AND CANT REMOVE IT CANT YOU GIVEME SOME ADVICE?

@LegitRaceCraft 10 лет назад

If the insides of the spark plug came out you can screw a tap into the now-hollow spark plug and reverse it out or tap in an easy-out reverse drill bit

@pantherax1 10 лет назад

the sad part that thing is HARD AS HELL the piece got broken, we use a manual tool with the bit and the bit got broken

@mattstone3422 9 лет назад

You have to drill a hole in the center and tap it then put a tight screw in it and back the bottom of the plug out if its snapped flush with the engine I do it every time and it saves me a shit ton of work

@andrewmunz1639 8 лет назад

mine isnt the same its an FZR,this one is an FSeeR

@hudeystar 9 лет назад

you forgot to put o-ring back to main jet. you drop it on that table :P

@LegitRaceCraft 9 лет назад

Altti Huttunen I see, I probably found it after I shut off the video and put it back in, honestly it's been too long to remember

@Jlaaman 7 лет назад

Altti Huttunen that main jet o-ring, can it be hardened so hard that you have to scratch it off in crumbles with a needle? I did not get any o-rings out under my main jets, but could see a black ring around brass tube in there in my mikuni bdst38 carbs. I scratched one off, but im uncertain about the other carbs now, because it was really solid stuff...

@fordrac1ng81 8 лет назад

How do I get the throttle cable off of the carb?

@LegitRaceCraft 7 лет назад

+Travis Howe info remember correctly, loosen one side with a 10MM wrench, then turn the piece of the carb that the cable pulls. You can slip the metal ball out of the slot once tension is off.

@djclarkdaddy1648 9 лет назад

I keep getting lost in all the back stories about EVERYTHING you touch like seriously just stay on track and do the job the video is supposed to be about lol

@benjaminpontius3092 7 лет назад

Where do you get your diaphragms i just bought a 2002 yzf600r and I'm cleaning the carbs but one of the diaphragms is ripped. also where do you get your complete kits as well?
