I have been riding around on my 2007 cfmoto v3 250 for a while now and I always wondered if it was possible to replace the engine in a v3 250 entirely with a larger capacity engine?

I like my bike but need an upgrade, I'll keep it if buying a higher capacity engine will cost less then $2500, otherwise it'll be sold for chump change and I'll save for a more powerful bike.

Just putting the feelers out there, I've seen new v3 250 engines for $1000 online, but don't know if any other motorcycle engines would fit the same bike, if someone could let me know that'd make me a very happy guy.

I hope you find the info your looking for, but I have found it's better to just buy a bigger ride. By the time you get so far into the project, you have so much time and money into it that you wish you have never even started it.

Save you money and time and buy a bigger bike.
