Break-In Period
Engine and Drivetrain Break-in
1. Fill the fuel tank with gasoline. See page 35. Always exercise
extreme caution whenever handling gasoline.
2. Check the engine oil level on the dipstick. See page 97. Add oil if
necessary to maintain the level between the safe and add marks.
3. Drive slowly at first. Select an open area that allows room to
familiarize 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 58.
6. Pull only light loads.
7. Check fluid levels of transmission and all gearcases after the first 25
hours of operation and every 100 hours thereafter.
8. Change both the oil and the filter at 25 hours.
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
during the break-in period.
If a belt fails, always clean away all debris when replacing the belt.
