High Altitude PerformanceA djustment: Over 4000 Feet above seal level
for all 1978 – 1990 models
The EPA requires the manufacturers of motor vehicles to provide
altitude performance instructions. (This requirement is applicable to
all motor vehicles to which Title II of the CAAap plies).
To improve the emission/performance of low altitude vehicles when
operated at a high altitude, a main jet change, as recommended on the
enclosed list, is necessary.
When such a vehicle is changed to high altitude settings, a label (see
sample below) must be affixed to the rear fender next to the original
vehicle emission control label. This label should be requested through
the Motorcycle Service Department in writing by quoting:
No. 2 121 222
For customer information purposes, please display a copy of this
Service Information in your showroom or customer waiting area.
