I am rebuilding a 1979 650 Special II. The bike had frozen engine. I have taken apart but broke a piece from cylinder cooling fin so am looking for another on eBay. I noticed some sellers indicating that the cylinder is for a YM159B, or YM252B, or SM254 engine. What are these designations and should I care? I have looked up part number for cylinder on Bike
Bandit and found 2M0-11310-00-00 so as far as I can tell there is on one cylinder used on several engine models. Can anyone verify that?
Also new parts are hard to find so you have to buy used. Does anyone have recommendation on how to approach. I found a big bore piston kit with new pistions, pins, and rings. Should you just plan on boring oversized or pay more for best cylinder you can find and hope you can just hone and reuse your old pistons?
