I have a 90cc baja atv and I had the little idea in the back of my mind to do an engine swap to a larger engine any ideas?

 

I just recently converted a mini falcon, 90cc into a 110cc. Got the whole top end kit complete with gaskets and cylinder for less than $40.

 

I would think any of the 90-125cc engines would fit it the engine mounts are the same.. main difference in that size engine from China is where the starter is located.. some are on top.. others are on the bottom of the engine.
