Has anyone motorized a bicycle?

Since it is a two cycle engine you can probably double the horsepower with very little expenditure of money. Altered port timing, mild compression boost (don't get carried away here or the primary compression--on top of the piston--will overpower the secondary compression--in the crankcase--and fuel/airmixture won't flow through the transfers as well) and an expansion chamber should make a world of difference.

Here's a bike built by a guy on another forum that I frequent. Since his name is "Hough", he calls his bike "Houghmade"

I'm reconsidering this with my 11yo huffy. My only concern is any form of registration/ insurance it would need

under 50cc = no need as I understand it...

the kit i'm looking at is 66(?)cc

just dont get caught is the best I can think of

doubt the cop is going to pull it apart to check ;-)...

I should put one on a 24" bmx bike.
