outside this temperature and/or altitude range. The

jetting installed in production is not intended for all

altitudes and/or temperatures. In addition, air screw

/ pilot screw adjustments and PVT adjustments may

be required to suit operating conditions.

CARBURETOR JETTING

CAUTION:

A main jet that is too small will cause a lean

operating condition resulting in serious engine

damage. Select the correct main jet carefully for

elevation and temperature according to the ATV

specifications charts in Chapter 1 or in the

Owner’s Safety and Maintenance Manual for each

particular model.
IMPORTANT:

The following guidelines must be

followed when establishing a main jet setting:
1. Select the lowest anticipated temperature at

which the machine will be operated.

2. Determine the lowest approximate altitude at

which the machine will be operated.

3. Select the correct main jet from the chart in

Chapter 1.

4. Clutching changes may also be required for

changes in elevation. Refer to clutching chart in

Chapter 1 for recommendations.
