Yamaha R1 carbs leaking fix.

[@ChadBIsRacing]

Hey, thanks for taking the time to make this video. I'm going to give this a go on my buddies carbs. He's brought this to 4 shops, lets see if I can knock this one out of the park.

[@yamaar1rider]

Thanks mate, strong thread round stop adj springs is a must to stop them disapearing round the workshop and careful not to scrap the tubes on the walls inside the carbs as you angle them in or under the o rings as you get them out. cheers Andy.

Just finished this procedure and wow I feel like a real mechanic after that haha thank you so much for this walkthrough

[@yamaar1rider]

Great glad you sorted it, happy riding 👍

Hi Buddy How are things going for you Hey just have to say thanks for your help I did my carbs got the butterfly's setting's best I could by eye put her all back together.

Thanks. My 99 R1 leaks there. I'll be doing mine like you did. Thanks for explaining this 😊

[@yamaar1rider]

Thanks Wayne, don't forget to do the float bowl rubber gaskets while the carbs are off. Good luck 👍

[@waynetetley584]

@@yamaar1rider Thank you. I did those when I did a jet overhaul this summer. At least I know how to get the carbs off now! Much appreciated, Wayne 😊

I was wondering where that Copper washer came from. Thanks for the video. I got them all back together and had that one piece left over.

[@yamaar1rider]

Glad it helped you mate. Safe riding Andy.

Amazing video thank you for uploading.

[@yamaar1rider]

Glad it was of use to you 👍

[@richmead9569]

Excellent video! Now I know where the small copper washer I have left should go, now its carbs back pff🙄. Also, do you have the correct size of the O'rings for the link pipes? Thanks in advance👍

[@yamaar1rider]

Cheers mate, should say in the description text 👍

[@johneley5680]

Morning buddy Should there be a gap with the butterfly's I thought they should be seated flush

[@yamaar1rider]

Hi, I find it's the only way you can see they are all exactly the same is to have a minute gap of light showing through each one as if you can't see where they stop when they are completely shut you won't know they are moving off the stop at the same time this works fine for me. Good luck 👍

[@johneley5680]

Thanks Buddy

What kind of o ring pack did you get? Was gonna order it and just wanna be sure the kit I order has the exact o rings I need for the crossover tubes.

[@yamaar1rider]

Hi, Marksman 225pc item code 62037c : R-05 in kit : inside diameter 6mm : section 2mm : which is 10mm over all, from Ebay. It may also be usefull for you to know that as they get older they can leak on startup when cold, a short term or you can do it all the time on startup is dont mess with the choke put it full on and leave it on till warm, this sometimes stops the leaking until everything expands and seals any tubes that are leaking. cheers Andy.

I have just got my carbs off as it’s running like a bag of nails. I am quite nervous about checking them over. I was just going to check carbs over for waxing etc as it’s been sat still 8 months. Them round seals were they leaking before? Did you change the gaskets or were they ok? Great clip very helpful.

[@yamaar1rider]

Hi, Yes they were leaking before, it was the reason I striped them down. The old paper gaskets weren't damaged so I put them back but the seals on the fuel tubes had hardened and squared off, which was the leak, I have also found if they still leak it is likely to be on start-up when the bikes cold so start with choke full on and leave on till warm knock it back slightly if it stutters and wait probably 2-4 minutes don't run it though if it still leaks down the left hand side, that's the left on mine, don't ride it if leaking a few drops of fuel should stop when warmed up, if not you may have to have another go at it I'm afraid. Good luck Andy.👍

[@MrRyan6616]

I have a 99 r1 that I did carbs and sync it runs perfect when cold as soon as it gets warm it starts to misfire and won’t run. Once it sits over night same thing again

[@yamaar1rider]

Hi, If you have striped and cleaned the carbs, there are a few things you could try, firstly with the choke on and it reving it is sometimes difficult to tell if all cylinders are firing so as a matter of course I would pop some new plugs in unless you have already, if you know someone with the same bike a coil pack can sometimes go bad that's trying the electrical side. Possibly if you have a aftermarket exhaust the air screw settings may change the book setting is 3:1/8 out from stop I do have a straight through exhaust and have found I need to put them at 3:3/4--4: turns out you sound like you are needing a higher or more fuel to air mixture when warm as the choke is blocking off the air and incressing the fuel, I think first I would try turning the piolet air screws in to probably 2 turns and go from there could also be worth adjusting the needle position, although if Im honest I would guess there is still a problem inside the carbs as the bike I guess ran nicely in the past. sorry I cant be more helpful. Regards Andy.

[@MrRyan6616]

@@yamaar1rider I will definitely try that and see if it helps. I does have straight though exhaust as well so it very possible that the mixture is off a little bit. I did think about the coils but I have no extras and I don’t want to just replace parts unless it’s necessary. I really appreciate the response and will let you know what I find thank you 🙏

[@yamaar1rider]

@@MrRyan6616 ok let me know how it goes, I do have a spare coil pack I tried on mine, didn't find it to be that when I was having troubles, you could have tried that but I'm guessing you could be anywhere in the world 😄 I'm in England Leicestershire. Cheers Andy 👍

[@johneley5680]

Buddy one last thing I can tune & get the butterfly's to sit nice But Only 3 doesn't matter what I try always 1 of the fly's sits flush number 4, or 1. Adjustment is 123. Gaped with 4 flush Or 234 gaped with number 1 flush Any suggestions please 🥺

[@yamaar1rider]

Hi John, no sure you should be able to sit them all level with the screws but obviously that's not possible for you all I can suggest without seeing it are possibilities. Butterfly loose, bent or worn, shaft worn can't think of anything else ☹️ Andy

[@johneley5680]

Ok buddy Thanks for that It's what I thought 🤔 So I just have to see what I can do She is getting old hahahaha 25 now 1999 Happy Riding ☺️ Thanks 👍 for ya help John

@@johneley5680 another thing is are all 3 cables slack ? cheers John

[@stephenmacdonald912]

I put a throttle cable on mine i cant get the dam carbs back on. I tried everything other than beating on them with a hammer.

[@yamaar1rider]

Keep calm mate have a cup of tea, make sure the screws are backed right off on the rubbers, bit of WD on the rubbers they are at a strange angle but preserve a headlight will help you see if they are twisting and the rubber lips turning in, someone else holding light pressure on them as you line them up, they do have a habit of slipping back off if you release the pressure before tightening the clamp screws. Hope all goes ok. Regards Andy 👍

[@stephenmacdonald912]

I just dont see how to tighten the rubber clamps after you get the carb on. Id need a special tool. I was able to pull it off without loosening them
