I'll agree with Johnny Seabass! Unless you want to play mig welding Captain Cobble.... You'd be better off to find a crappy liquid R.
But as far as what you were asking Matt, the 1st generation X frame is a bit cramped for space. Not an easy bike to stuff another motor into - unless it's done poorly.
I can see where your coming from and maybe you have access to a cheap 250 powerplant but a liquid R roller would be more spacious! You certainly wouldn't be happy with a Lifan after the Zilla!
I hope you don't find a liquid R roller
- THATS what I've been looking for to start another project......
Good luck though and the welders and everything else are here if you need help
