Motor swap

[alphaomega804]

I've seen people put different motors on the frame of these warriors but I'm not sure what motors they are.instead of putting extra money into this motor I was thinking about putting another motor in.can anyone tell me which motors will fit into the frame with or without any frame modification?

All the ones with streetbike engines you see all have frame modification

There will always be some frame mods to swap an engine. Most times it's brackets fire engine mounts that are the issue and the Swingarm pivot. Usually the swinger has to be cut and modded. I really don't recommend a swap for anyone without some good fabrication skills.
