New from Pinasco comes this cast-iron performance kit for 2-port largeframe vintage Vespas. No longer do you have to mess with cutting extra ports or custom base gaskets! Bolt this on to your VNB, VBB, GL, Early Sprint/Super/GT and unleash the power! This will boost your displacement to 177cc (for all models) and give better porting for an engine that breathes! This is the ONLY kit on the market for 2-port largeframe Vespa scooters! Great in combination with a 20/20 or 24/24 carb and a sport pipe ! 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. Caution! When removing excess material, be very cautious. Any damage or modification to the cylinder is the sole responsibility of you, the owner.
