jamieyz426f01   Posted October 17, 2005 my yzf426 was running reasonable(bogged on the bottom) because i put an aftermarket pipe on it. so i tried to correct the bog by moving the needle clip DOWN 1 notch, i also messed with the pilot screw and can't remember where it was before🤣🤣. it now only idles with the choke out and backfires real bad on deceleration. would appreciate your advice greatly Share this post Link to post Share on other sites

jamieyz426f01 Â Â Posted October 17, 2005 where is the fuel screw set now?set it at 2 turns out for a test. oki doki, i think i have got it at about 1 3/4 (going from the manual, the manual is for the 2000 model though ) do you think it is anything to do with needle clip?

jamieyz426f01 Â Â Posted October 17, 2005 did you take the enitre slide out at any point? yes, and from what i remember there was one wheel that kept falling off, the plate that is on the slide fell off so i cleaned it up and put it back how i thought it came out. thanks Share this post Link to post Share on other sites
