OPERATION
Vehicle Break-in Period
Engine and Drivetrain Break-in
1. Fill the fuel tank with gasoline. See page 28. Always exercise
extreme caution whenever handling gasoline.
2. Check the oil level. See page 88 (325) or page 91 (570). Add the
recommended oil as needed to maintain the oil level in the safe
operating range.
3. Complete the New Operator Driving Procedures outlined on pages
56-57.
4. Avoid aggressive use of the brakes.
5. Vary throttle positions. Do not operate at sustained idle.
6. Pull only light loads.
7. Perform regular checks on fluid levels, controls and areas outlined
on the daily pre-ride inspection checklist. See page 51.
8. During the break-in period, change both the oil and the filter at 25
hours or one month.
9. Check fluid levels of transmission and all gearcases after the first 25
hours of operation and every 100 hours thereafter.
Brake System Break-in
Apply only moderate braking force for the first 50 stops. Aggressive or
overly forceful braking when the brake system is new could damage
brake pads and rotors.
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 any debris from the PVT intake and outlet
duct and from the clutch and engine compartments when replacing the
belt.
