A buddy of mine is selling his CRF250R (paco on here). It has a 280cc big bore kit. I know he recently had the entire topend redone as well. Bike runs AWESOME as I've ridden several times. Cranks first kick. Has new aluminum FMF Powercore exhaust with aluminum FMF Powerbomb header. Here is more detail about is bike from his CL ad http://bham.craigslist.org/mcy/1690969433.html
