I was wondering what is the visual differences of the 50cc to the 70cc engines? I see the two side by side on the internet web pages and they look exactly the same. How do I know if i actually received the 70cc that I bought? Also, if a cop pulls me over, will he be able to tell the difference if I say it is a 50cc when it is actually a 70cc.

Thanks,

Ben

I expect you would have to measure them to tell the difference. As to the cop they are all unmarked so they are all 49ccs...

Pulling the head off and taking a quick peak at the piston size should tell you. And yes, they are all 49cc...unless they want to pull the motor apart and check it, they will never know.....
