If you have a good stream, you need to adjust the AP timing screw (next to the throttle wheel) 1/2 turn CCW, test ride. SAhould not need more than 10 minutes to resolve

Thumpsterman, An alarm bell went off when you asked your question! When was the last time you checked the valve clearances? My guess is that they are tight, and are causing your issue. Check them now!!! The engine has to be completely cold, so check them first thing in the morning before trying to start it. Hope this helps.

A neighbor of mine though is giving me his Yoshi pipe from a YZF 250 and I know I'm going to need to do some rejetting so I was kind of putting it off. Do you guys know the amount it usually goes up when putting on an aftermarket pipe? I've found a guy with the same bike that lives in the same area on the jetting database, but he has a stock pipe I believe and hasn't signed on in forever. Is there a general number that it usually goes up? I think the pipe leans it out, so you'd need to go up a couple, right?
