I just removed the airbox lid, no other modifications. I moved the clip to the bottom position on the needle, and installed a 168 main jet. The motor runs fine, much more power actually, up to about 90% throttle. Between 90% and 100% throttle, I hear a distinct "Bwwaaaaaa," come from the airbox, with no noticable increase in power.

I am assuming that the main jet is just slightly lean, but could be wrong. What would you guys suggest, go up one or two jets? Or if I've got it backwards, down one or two? It's a real pain for me to get to the cycle store before they close, so I'd rather get it right with my next jet. Any help will be appreciated. [img]i/expressions/face-icon-small-wink.gif[/img]
