My mechanic pulled a couple of good SBT cylinders off of a ski he's working on. These are SBT cylinders, so they have to be used with a 3rd SBT cylinder; don't try to run a mix of OEM and sleeved cylinders on the same motor. One of them has a good SBT piston with it. PM GoFastGuru or myself if interested. He hasn't posted enough yet to post on the classifieds, but I'll stand behind his goods.
