98_shee Posted May 14, 2010 Report Share Posted May 14, 2010 The main sounds close. Why did you rejet, what was your jetting before you rejeted it? I had a bike with simular mods without an airbox and it was jetted at 158 main, 48 pilot, N68a needle middle clip, air screw 1.5 turns out.

Larry's Shee Posted May 15, 2010 Report Share Posted May 15, 2010 Timing plate or key? If key maybe you put it in backwards. Why did you change jets?What were jets you took out ?Did you change anything else at the same time ? Try it with jets you took out. Quote Link to comment Share on other sites More sharing options...

98_shee Posted May 15, 2010 Report Share Posted May 15, 2010 Did you sync the carbs? You should do a plug chop to see if 150 is to lean. Quote Link to comment Share on other sites More sharing options...

streakx Posted May 17, 2010 Report Share Posted May 17, 2010 does it revs easy but doesn't pull that hard ? if so probably lean ... also make sure you didn't -4 your timing (sometimes we do some dumb shit without being dumb lol) Also .. does it pull ok from 0 to 1/2 throttle (like before) ?
