Periodic maintenance and adjustment
TIP
 Air filter
• This model's air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com-
pressed air to avoid damaging it.
• The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
 V-belt case air filter
• The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
 V-belt
• The V-belt should be checked at the initial 8000 km (5000 mi) and every 4000 km (2500 mi) thereafter. Replace the
V-belt if any damage or wear is found. The V-belt needs to be replaced every 25000 km (16000 mi) even if there is
no wear or damage.
 Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level. After dissembling the brake master cylinders and cal-
ipers, always change the brake fluid.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake
fluid.
• Replace the brake hose every four years and if cracked or damaged.
 Fuel system service
• Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as
9
the valves and piston rings, as well as to the exhaust system.
• Replace the fuel filler cover every two years or if cracked or damaged.
• Check the fuel filter if clogged or damaged every 12000 km (7500 mi).
 Battery service
• Check the condition and service every 3 months.
• Recharge the battery immediately if the voltage is less than 12.4 V.
• If the battery tends to discharge, replace it immediately.
• If the vehicle will not be used for more than one month, remove the battery, fully charge it, and then place it in a cool,
dry place.
