OK, should this happen to a new motor. Less than 2 hours of run-time and 39 miles traveled. Break-in oil mix 24:1. Brand new Grubee 66/80CC Skyhawk Angle Fire head. CNS V2 Carb. I got it from Piston Bikes.
See the photos.
Did I do something wrong or was this motor defective.
And prior to this after only 1 hour of run time and 19 miles the head gasket blew. Looked like it was put on bent at the factory.
At a minimum I need a new piston, cylinder, head/cylinder gaskets. But is this worth fixing as there appears to be quite a bit of piston pieces in the crankcase. ?
If I decide to fix this, will I have to do a complete tear-down? I know, I probably should if it want it to last.
