Sorry for this post about a kids bike here but I thought that someone here might know the answer. Below is what I posted to the kids bike forum.


I have 2001 Scrambler 50. Is it possible to change the top end of the engine to a 90cc.

What I mean is, can I remove the cylinder, piston and rings from the 50cc and replace it with a 90cc cylinder, piston and ring set?

Could I just buy the 90cc cylinder, piston and ring set and bolt it on the the 50cc lower half and now I have a 90cc machine?

Any help would be great.

Scott
