Default How durable are these engines?? 66cc

ok so i ride motorcycles and i ran into these little things, and i would like to build one. my question is how reliable are they?? im looking at a silver eagle engine from jakes custom bikes (pk-80) and im going to get all possible upgrades for that engine...i mean but my only concern is that these are chinese, so how much can they stand?? i will be putting it on my mountain bike and i will go trail riding with it, which means frequent hills at full throttle, i would be riding this thing as if i was riding my own dirt bike.

so assuming i will be doing all this how well can it withstand this abuse??

few months?

few years??

or not at all??
