Default Re: How durable are these engines?? 66cc

thanks again for all the replies!!

what if i put on a 5.4cc high compression head, you mentioned that the cylinder walls where thin so would that blow a hole in it? lol

also for the silver eagle engine (pk-80) is it really better than those ebay kits out of the box?? cause the description says its a more true crank, and high performance japanese bearings. anyone tried this engine?? or is it just a market scam?
