2005 kx250f in need of some help

Recommended Posts

I had a recent issue with the bike, no compression, would start when pulled behind the four wheeler but not kick start. Took the head off and the valves were pretty much gone. I ordered new ones and new piston rings just in case.

Now after reassemble the bike feels like it has great compression, wouldn't kick start still but has a lot more power when we pulled it off. Didn't ride but a minute to not harm anything else. Now as far as shims go, I did not change. We did check them and both sets of valves are taking a feeler gauge at least 3 sizes higher than suppose to so I know the valves are to loose meaning I need to order a shim kit and go with bigger shims. Now is this why my bike still wont kick start? Its so tough to kick and is this because when the lobes are turning the valves are probably barely opening causing to much trapped air? Just want to make sure Im headed in the correct path. Thanks guys.

btw:

the pipe got red hot and is was also shooting some flames somewhat
