New Bolt In Engine

[BradZ_09]

Hey all, after having clutch problems, took my engine out, for the first time lol and after seeing how easy it was, I'm wodering what engine could i get with a bit more punch to replace a Force 25. Needs to bolt straight in.

what size is your current engine? and i recomend O.S as far as a good brand

Current Engine is a Force .25 - 4.01cc
I think its got something to do with O.S as I've seen it a few times in my manual, their logo i mean.
