Also after accelerating hard in the midrange when I back off the throttle it like the engine cuts completely for a second, its getting really annoying and downright dangerous when going through whoops. ...

It runs like a turd and I want to get this sorted out. Some signs point either way. Here's the facts: -When I whack the throttle at idle it will want to die unless I back off -Starts great when I give it gas and kick. One kick usually when it's cold. -Need choke on a cold start even though it's (90+ degrees) hot out (not sure if that's normal). And some other times when the bike's warm. -Will idle high after it's warm unless ...

If anyone out there could lend me some knowledge that would be awesome. The problem i was having was that the bike did not want to idle down using the 68s pilot jet, trying to adjust the idle air/fuel screw only seemed to make the engine run faster as i screwed it in so i moved to the smaller jet. This surprised me as it seems that everyone with this bike runs a 68s once its uncorked. If anything i'd expect to ...
