I have a cylinder with a new cool head, and has a fresh sleeve job. I believe I even have the piston, wrist pin & bearings, the billet thrust washer too! If you're interested pm me what you had in mind. It's somewhere in my closet collecting dust. LOL I know I paid $450 for the cycling alone. But I knew I was getting a quality job. If I was you, I'd have Carl aka ICERACER, reinforce the cylinder, and really, I'd just send it all to him. He's got the knowledge and means to do ALOT of things to make the 250 exactly what your looking for.
