YAMAHA BANSHEE FORGED SUPERSTOCK PISTON KIT 65.00MM. This is a complete top end piston and gasket kit. The Superstock piston was designed to add H. We basically ported the piston instead of the cylinders.
The top of the piston on the exhaust side has an angle cut to let the exhaust escape sooner. (the same thing can be achieved if you raised the exhaust port with a porting tool) The intake windows are raised for a longer intake duration. Mid to top can be gained after installing these pistons. Re-jetting of the carburetor will be necessary to accommodate the extra H. THIS IS FOR A STANDARD OEM CYLINDER +.
Kit includes: (2) Forged Superstock pistons, rings, wrist pins and circlips, upper rod bearings and a top end gasket kit. The item "YAMAHA BANSHEE SUPERSTOCK PISTON KIT 65.00MM BORE SIZE ADDS 8 + HORSEPOWER" is in sale since Monday, October 2, 2017.
