I've had mine since this past October. After removing the throttle stop, airbox restriction, uncorked the exhaust and richened up the TPS , it really came alive. My TPS was set at .42, i set it to .62 (if memory serves me correctly) and the lean pop, and excessive heat, went away. Much smoother idle and easier to start. Its a little rich while poking through some slow tight trails but nothing bad by any means. I agree with stupidmoto, It is a little heavy feeling at times. I'm 5'9" and around 190. All I need now is a bit softer clutch springs as it does have a heavy pull on the clutch. At least for me it does.
