you were able to "push" the piston down? I assume without pulling the clutch. Thats pretty bad. I think your engine has been destroyed.
This engine kit is very inexpensive and in my opinion, bulletproof. This engine is also the most powerful of my engines out of the box. It has a different design than traditional engines, not that it is "better". I ride this engine 32 miles a day commuting, (when I use it). I have gotten it so hot it melted my plug wire.

So I just got done with a 15 mile wide open throttle the whole way ride... I stopped and my spark plug boot was smoking. The red it used to be turned grey! I went to take a pic and realized I left my phone at work. Gonna be a 60 mile day boys! BRB
