Yamaha Banshee Cylinder

The Banshee is a very similar engine to the Yamaha RZ350 (or RD350LC as it is known in Europe) except that it does not have RPM adjustable powervalves. The area where the powervalve is located has been removed from the casting. I don't know the reason the powervalve was removed but the rest of the engine is the same as the road based RZ350.
