Re: Can you unbridled your 48cc engine ?
No way, as long as you wear a helmet and dont be a jackass on the road, cops leave you alone. I have been pulled over once because in Virginia you need to have a windscreen type helmet. that was 8 months ago and i haven't bought a new one... still no problems though.
in conclusion, they will have no way of telling what displacement your engine is as long as you remove the sticker on the side. Even then they normally don't care.
