Re: Soooo frustrated now
The only experience I've had with a 'no oil' situation was with a bike I built for my wife's nephew. The piston was seized so tight in the cylinder bore that it took a wooden hammer handle to drive it out. The cylinder walls were toast, the rings embedded into the ring grooves.
I don't know how long it ran before it seized. The kid swore he had put oil in it and had ridden the bike several times. "It just quit" he said, "and it wouldn't start again and the back wheel locked up". The fuel left in the tank was straight gasoline. No evidence of oil.
Oddly enough the bottom end seemed to have survived unscathed. The bearings were good. I replaced the top end and sold the bike. That engine is still running fine.
