4 stoke motor swap for Rampage MT?

[Slater__boner]

Is there a motor that just runs on normal pump gas?

Great question! I cant think of the smallest 4 stroke I have seen. Besides a 3.5 briggs n stratton! Good luck man. Lots of other great 2 stroke options tho.

You won't get the same revs out of a 4 stroke so you'll have to find gearing to suit and a clutch that will handle it.

Most likely Honda makes the smallest ones:

Lacking revs and power for this kind of use.
