HOW DO I RESYNCH THE CARBS ON A 1992 FZR 600, WHTS THE ADJUSTMENT ON THE AIR FUEL SCREW ( THE SETTINGS ) TURNS IN TURNS OUT....ETC PLEASE AND THANKS IN ADVANCE

SOURCE: My FZR 600 is acting up and backfires

I have had several bikes in my time. and keeping the carbs syncranized is very important. Did you put aftermarket pipes on it? try rejeting the carbs up 2+mm that may help the fuel air ratio?

hi m8,, pretty much any fzr motor will fit,, the only thing thats different is the water pump pipe from the rad to the pump at the bottom of the motor,, so may have to re route it,,check that 1st b4 gettin the motor, appart from that all engine bolt holes will line up and the rest will fit,, cheers m8

SOURCE: fzr 600 got killer spark pulls fuel valves in

This is not the news you probably want to hear but backfiring thru the carbs when you have good spark can be one of 2 things... either the valves are sticking / not closing properly due to carbon or the cam timing has shifted from the original position.

It would be best to do a compression test. You should have a minimum of 100 PSIG for an engine with major problems and up to 150 for a healthy engine. If you can not get 100 PSIG then it will be time for some serious engine service.

There is a possibility of the kill switch wire in the handle bar grip grounding under the grip to the handlebar but, since you said you have killer spark I doubt this is your problem.

Thanks for using FixYa.
