High-Altitude Kits
NOTE:
Following conversion with one of these kits, the original main jet should be retained for possible future use.
If the engine is ever to be operated below the altitude specified for the new jet, the carburetor must be reconverted back to the original jet size, or overheating and internal engine damage can occur.
*altitudes are given in feet. 1,000 feet = 304.8 meters
**not emission certified
