does anybody know how to adjust the carbs on a 99 cbr900. it feels like its running too rich. when i go slow less throtle it feels like its loading up. when i give it more throtle it clears out. the engine and carbs i got were in a wreck. would that have anything to do with this problem. is it easy to sync the carbs or would it be better to have somebody do it.

 

i just recently had my carbs sync... i have a book and it seems easy but you need a carb sync tool which goes for about $100 so its better taking it to a mechanic its aboyt and hours work...

 

Its not easy to sync the carbs unless you have sound technical knowledge.

 

i have a carb issue too....
i was gonna rip them aprt this weekend and try to sync them- but it sound slike its not that ez....

cuz when i "goose" her it like bogs down, and than all of a sudden explodes out with power and i take off, but it sux cuz i want better response, so im thinking my carbs r way outta line.... so would it be better to just bring it in and have it fixed? or whats some tips u can give me?

 

i took the plugs out and the #3&4 plugs where dark meaning them two cylinders where running rich. so i adjusted the air fuel mixture screw on those two carbs and the bike runs awsome. no more black smoke. and its real responsive. so try some thing like that.

 

Yeah I agree unless you really know how to work on carbs it might be best to have someone who does do it, and you watch and learn.

Or go to a mechanic. Messing with the carbs can really mess up the bike.
