I have a 2006 BV500 engine that I replaced with another. This one had a rod rap, probably at the small end. I'm looking to get rid of the old engine to someone who needs parts. The variator and clutch is gone already, the top end is apart and the head looks OK. The cylinder "looks" ok to me, but I don't have a micrometer to measure the bore. The side covers are gone, the swing arm is here, the transmission was fine. No carb. Many pieces are the same as the MP3 500 engine of the same period. You'll be amazed how cheap it will be. Send me a PM with questions. Bob
