looking for carb rebuild service or rebuilt carbs for 2002

Hello everyone,

I have a 2002 FZ1 that I need to have the carbs rebuilt. I would be happy buying a set that are already rebuilt or sending mine in. Any suggestions?

Thanks so much.

Steve

Hello everyone,

Since I was unable to find a new set of carbs ready to go, I decided to clean mine and replace a few things. I wanted to ask for some advice. I saw this at the auto parts store and thought I could use it to clean the bodies, but couldn't remove the choke.

1) Do I need to remove this if I was to soak it in this parts cleaner
2) is this ok for the bodies?

Thanks

Steve

Only do that if you removed every bit of rubber from them.

And you created a nightmare by splitting them up.

I agree you should not of split the carbs up. Also do not use that stuff on your carbs.
When I did my jet kit on my 2002 I left the carbs together and just took each one apart and thoroughly cleaned each one with spray carb cleaner and compressed air.

I've posted here before that I prefer to split the carbs. Great opportunity to replace every O ring in the entire bank and makes them much easier to clean. I purchased an ultrasonic cleaner from Harbor Freight and it works a treat for jobs like this.

If you have trouble or want assistance, send them my way and I can give them the once over.

Best,
Ron

Because if you're going to rebuild ancient carbs with lots of old rubber, just do it once by doing it right. Splitting and reassembling carb banks isn't voodoo.

+1 on the HF ultrasonic, never going to sit and scrub and pick at orificies again.

I take apart the screws/jets and put them in an ultra sonic cleaner with 2oz Simple Green, pinch of Alconox (https://www.amazon.com/Alconox-Powde...H/dp/B003FZAQ2), and hot water.

I then find a big pot I don't use for cooking ever again, add the same mix and dump the whole carb body in for 10+ min, I've left it in for hours before no harm done.

Then air blow everything off and reassemble. It comes out cleaner and less toxic than using any carb cleaner.

I just did a basic carb. reseal on my 2001 FZ-1. I first pulled the carburetors, and replaced the needle seat o-rings. Thanks Jimco!! My FZ-1 was dropping cylinder(s), spilling gas out the overflows, caused by the leaking seat o-rings. Put it back together, and it now ran great, but was leaking externally, from what I assumed was from the old float bowl gaskets. Got a set of K&L float bowl gasket/seals off of ebay, and replaced them, and re-installed the carbs. Still leaking externally.... I new I should have pre-tested them!! I see now that it is the fuel pipes between the carburetors that are leaking. This will require splitting the carbs.The o-rings are a service item, but I bought a Viton o-ring kit from Harbor Freight. Replaced all 8 o-rings on the fuel pipes, and also the air vent hose tees. The trick is to cover a bench, or desk, etc in rags, and sit down to do the the job of splitting/reassembling the carbs. Nice bright desk lamp, and smaller led light, also. I backed the throttle screws out 2 turns, to help to pry the spring, and insert the lever. Do the vent hoses afterwards. I did carbs 1&2, then 3&4. assembled the 1&2/3&4 sets together, then install the long screws and spacers. Long spacers go in the middle. Leave the screws loose, and carefully pry the carb sets apart, and install the little stand offs between carb 2&3. Tighten long screws, and reinstall choke linkage. My FZ-1 runs great, even without a carb. sync. Oh, I got pretty good at removing, and installing my carbs.,also.

If you don't split carbs for rebuild then you miss all the fuel log o rings and will have the joy of going back for a second time when they start leaking.

Does anyone have a link(s) to instructions for rebuilt the carbs with splitting the carbs?

Now that I have sold my 2005 R1, I would like to get my 2002 FZ1 running again.

I let my 2002 FZ1 sit too long. I would like to get the carb rebuild right the first time. I really don't want to pull the carbs again.

I have the carbs out already. I used the instructions from the FZ1OA CD that I purchased years ago to get them out. Thank you very much to Pat for the CD.

Thanks,
Eric
