High Altitude Adjustment
When operating this FOURTRAX at altitudes ranging above 1,000 m
(3,000 feet), the air-fuel mixture becomes overly rich. This may result
in poor engine performance and increased fuel consumption.
A high altitude jet is available to compensate for high altitude richness.
For those who are mechanically proficient and have the necessary
tools, installation and adjustment procedures are given in the official
Honda Service Manual available from your Honda dealer. All others
should have this carburetor modification performed by an authorized
Honda dealer.
Sustained operation with the high altitude jet at altitudes below 1,500
m (5,000 feet) may cause engine overheating and damage.
