My brother has a 250 four stroke for sale if you'd be interested in that. It's a badass bike and setup right. It's a 04 CRF250R with SS valves, new piston, shocks revalved, and FMF power core exhaust with power bomb headpipe. All work was done by BUMPSTIKS in MD which is one of the best guys on the east coast. It's never been raced, he estimated 15 hours before the valves and new piston and 6-8 hours since. He built it wanting to race but didn't and has only been ridden around the corn field a few times a year. He said he would like to get $3000 out of it.
