Top seized or bottom?

It won't kick over at all and I went through each gear while the back was on a stand and I couldn't get the back tire move unless it was in neutral.

Did you tear it back down yet?

No that's the plan tomorow was just hoping to gain some insite before doing so, can't see why she would lock up like that

I could type volumes on this subject and may still be wrong.

Nothing will tell you quicker than a teardown.

Connecting rod bearing was toast, bottomed out my piston broke the skirt, I replaced the crank and bearings new piston and rings, bike runs great now
