I have a 250x frame with a pretty decent chassis set-up.I am looking to upgrade to a larger engine.I know of the popular 350x conversion done on these bikes but was wondering if there are any other engines that will work without a ton of custom fabrication.I have access to an xr650 engine but havent actually seen it yet so I am not sure of the physical size of it.Any help would be greatly appreciated.

 

i was looking to do something similar to that

nobody answered me either i wanted to try an xr650 engine
