Good To Know
Q: Is this piston kit a direct replacement for standard Yamaha Blaster 200 pistons? A: Yes, it is designed as a direct replacement when using a .020 over bore cylinder.
Q: Do I need to rejet the carburetor after installation? A: It is recommended to check jetting after any top-end rebuild, as the slight bore increase may affect air-fuel mixture.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
