Manual background High altitude operation

At high altitude, the standard carburetor air-fuel mixture will be ex- cessively rich. Performance will decrease, and fuel consumption will increase.

High altitude performance can be improved by specific modifica- tions to the carburetor. If you always operate the engine at altitudes higher than 1,500 m (5,000 feet) above sea level, have your authorized Honda dealer perform these carburetor modifi- cations.

Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 300 m (1,000 feet) increase in altitude. The effect of altitude on the horsepower will be greater than this if no carburetor modification is made.

SLOW FAST

Operation of the engine at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.
