silencer installed. Severe engine damage

of the “Main jet selection chart”.
By checking the condition of the spark plugs, it
is easy to get some idea of the condition of the
engine. This may diagnose potential problems
before engine damage occurs.
High altitude tuning
Use the chart in CHAPTER 9 to select main jets
according to variations in elevation and temper-
ature.
These jetting specifications are subject to
change.
Consult the latest technical information from
