Thats a chance you take when you buy anything from ebay or here for that matter. It does say it needs a rebuild, but i thought i would throw it out there for him.
oh yea i already talked to him he was selling it here now he got it on ebay. besides it wouldnt fit if i rebuilt it i have a 72.20 mm wiseco BB piston and all i need is the cylinder but if i cant find that i will just buy a BB sleeve and get my stocker sleeved to the piston size and get a port job done on it... this is why im still selling my parts and if i can they will be on ebay soon.
I have one that needs a bore to it. It is stock 72mm now. comes up as 71.9 at the machine shop they wanted 65 to bore it .020 over. It has decent porting done to it now. PM how much you want to spend and Ill send pics if your price is in my interest
