having prob with mid range badddddd!just bought 28mm pwk's from a buddy dont know what jettin is in the carb runs nice on top end and the plug is burning great. but mid range sucks i checked the needle and its all the way at the top of the clips at the leanest position ive tried moving it down and my bike runs even more like sh@!.could it be a possibility that the carbs are jetted too high. and my plug still be buring good but make my mid rpm suck. didnt have the problem till i put the carbs on but at full throttle this thing screams but sucks in the woods. could anyone give me a starting point on the jettin i got 28 mm,reeds,spacers,fmf pipes,k&n air filter with holes cut in my air box. i live and ride in deleware and use 98 oct gas thanks for the help
