Break-In Period
Engine and Drivetrain Break-in
1. Fill the fuel tank with gasoline. See page 31. Always exercise
extreme caution whenever handling gasoline.
2. Check the oil level on the dipstick. See page 69. Add oil if neces-
sary to maintain the level between the safe and add marks.
3. Drive slowly at first. Select an open area that allows room to famil-
iarize yourself with vehicle operation and handling.
4. Vary the throttle positions. Do not operate at sustained idle.
5. Perform regular checks on fluid levels, controls and areas outlined
on the daily pre-ride inspection checklist. See page 45.
6. Pull only light loads.
7. Change both the oil and the filter at 25 hours.
8. Check fluid levels of transmission and all gearcases after the first 25
hours of operation and every 100 hours thereafter.
PVT Break-in (Clutches/Belt)
A proper break-in of the clutches and drive belt will ensure a longer life
and better performance. Break in the clutches and belt by operating at
slower speeds during the break-in period as recommended. Pull only
light loads. Avoid aggressive acceleration and high speed operation dur-
ing the break-in period.
If a belt fails, always clean away all debris when replacing the belt.
