真的瞎！用這種方法組引擎?在台灣，會跑嗎？

[@kazhisi]

Lol 70cc is not considered big bore. That means something like 80-100cc

[@alvinholmstrom2342]

Big Bore is considerd the inside diameter of a cylinder, so a 70cc can be big bored

[@camilo8cheryl]

That vertical engine has no potential for speed..

[@thatfreeamericantv923]

Cringey to watch you build
