Was riding along and it died electric start seemed locked up so tried pull start had to yank hard for it to turnover but no luck starting ... Got it home and checked for spark nd fuel both good ... what else could it be ??? Ive checked compression and is all good at 125psi.

 

It died for a reason! You say it's getting fuel,but make sure there's no kinked lines,plus clean the fuel filter. If spark is still good as you say,fuel flow has been checked out,then it's possible you could have had a partial piston seizure even if compression is 125 psi. Just eliminate all the other things first.Plus it's not uncommon for the crank seal behind the front clutch to pop out. I've had that happen several times. This will kill one quick!
