DR performance cylinder kit for vintage Vespa P/PX, Genuine Stella 2T, and Bajaj 3-port engines. These are the easiest kits to match to 2-port engines, requiring the smallest third port to be cut into the cases.

NOTE: This performance cylinder kit was designed to allow the best cooling characteristics possible. In order to do so, the manufacturer has created a specific layout of the cooling fins. On some applications, the cooling fins at the base of the cylinder come in contact with the flywheel. When this occurs, the fins must be ground off to allow clearance. Removing these fins will not hinder the cooling abilities of the cylinder nor will they subject the cylinder to premature failure. A simple grinding bit will work well for removal.
