wtb: trx250r big bore cylinder

[88mxR]

I have a 330 sleeve, piston, machined cases, and engine set up lined up. I'm kicking around the idea of building a big bore.

Any idea what a big bore cylinder is worth?

I will likely start from scratch, so does anyone want to part with one that is blown?

Thanks

my old man has a 310 cylinder that was recently cleaned up by CT racing and it has no hours on it. he also has a spare motor that has some sort of tranny problem. let me know if your interested
