Re: motor kit suggestions
ahh ya the fins are a little different in your pics, maybe they can tell. The 48cc engines seem to be less and less available/popular while the 66cc engines seem to be gaining popularity. It's also odd that 48cc's are more expensive now then than 66cc's. Supply and demand I guess.
Iv'e never heard of anyone getting in any trouble strictly because of the engine size, usually it's for something else - checking the engine size is a "bonus"
