I have what I believe is an 86 bottom end with a busted left case from a throw chain that I'm parting out along with a ported stock cylinder and 86 stock head. The cylinder is what I believe to be an 88 and looks to have plenty of room for bores with no gouging on scratches in the cylinder walls. The porting was done by a shop out of Tuscaloosa, AL and has their name engraved on the cylinder "Big Eagle Cycles" along with the date and what looks like the persons last name. It looks to be a pretty clean job with the transfers done and all too. I also have a new Pro-X piston that is labeled "CR25088" and is .030 over and it appears that the cylinder would have to be bored to fit this piston once rings were installed. If anyone is needing anything in particular, please let me know and I'll see if I have it and we can go from there. I have most of the bottom end minus the clutch hub and basket. I need rod measurements to tell if this OEM crank is long or short BTW.
