Good To Know

Q: Will this kit fit every year of these models? A: Model year and serial number changes can affect bore size and piston style, so match your engine code to the kit before ordering.

Q: Do I need to rejet the carburetor after installing this kit? A: A stock rebuild usually does not require jetting changes, but verify fuel mixture after assembly if the engine ran lean before the repair.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
