i have a 2000wz400 done all the free mod's,fmf power bomb header,pc4 silencer. after a nasty mud ride on sunday i had the tank,seat,side panel's to do some maintenance and cleaning. I decided to try the gray wire mod.I also put a new spark plug in. i putit back together and it ran like sh*t from idle to about half throttle while stopped and while riding it had a miss awhen it started to accelerate then it would clean out. i don;t think it helped it power wise at all.My jetting is 170 main 45 pilot pilot screw 1 1/2. the bike has run great since i've owned it and start's fin 1st or 2nd kick until today(it still starts fine) i tryed going both way's on the pilot screw didn't help.does the grey wire mod change the jetting? i didn't think it would affect that,any suggestion's guy's?
