YAMAHA BANSHEE 68MM BIG BORE PISTON KIT
KIT INCLUDES: 2 PISTONS, RINGS, WRIST PINS AND CIRCLIPS.
This is our new 68mm big bore piston with a stock piston pin location and 9 degree dome angle. We had this piston made with the Blaster style dome angle which is a flatter 9 degree crown angle compared to the stock piston 13 degree dome angle. 9 degree big bore domes will need to be used with this piston. Pistons will fit 68mm cylinders that use a 54mm STOCK STROKE CRANKSHAFT with 110mm rods Ex: 392 Cub cylinders, Athena cylinders, Vito's cylinders or any stock cylinder that has been sleeved for a 68mm bore size.
The intake windows are the same design as our stroker piston which is higher up on the skirt so when the piston is on the downward stroke it will have a longer intake duration allowing a little more fuel and air to be pulled into the motor.
*** REMEMBER THIS PISTON HAS A STOCK PISTON PIN LOCATION SO IT CAN ONLY BE USED WITH A STOCK STROKE CRANKSHAFT THAT HAS 110MM RODS.***
**IT WILL ALSO FIT A +4MM STROKER CRANK THAT HAS 110MM RODS BUT YOU WILL STILL REQUIRE A SPACER PLATE OR CUSTOM STROKER DOMES.**
