Always ask the workshop

A look at the operating instructions will tell you the maintenance schedule. Bikers with a knack for mechanics can carry out many routine checks themselves. Safety-relevant components like the brake system should be checked by a workshop.


Tighten the drive chain

How often the chain must be tightened depends upon the model (with or without O-rings), use, and lubrication. The important thing is: The sag of the chain may not deviate from the information provided by the manufacturer and the track of the rear wheel must be correctly set. This means: tightening the chain adjuster on both sides of the rocker exactly the same. Here, install a new cotter pin on the full-floating axle nut each time.

Lubricate the drive chain

The rear wheel may not contact the ground while lubricating the drive chain and must be easy to turn. To do this, jack up the motorcycle on the main stand and spray the chain spray while turning the rear wheel. This distributes the lubricant over the complete chain.

Air filter

If the air filter is missing, this results in a “leaning” of the mixture and leads to serious engine damage. Heavily soiled air filters, on the other hand, make the mixture too “rich” and not only has an effect on the engine performance, but also damages the environment. For this reason, clean or replace the filter regularly in accordance with the manufacturer’s information.

Motor oil

Pay attention to the manufacturer’s information regarding replacement intervals, amount, grade, viscosity, and changing the oil filter. In order to prevent the oil drain screw from loosening, this must be tightened with the correct torque (special wrench!).

Battery

The acid level may not fall below the minimum marking. Regular checking and possible refilling with distilled water extends the useful life of the battery
Caution: never fill with acid!

Tires

Arrows on the sides of the tire mark the correct direction of rotation for the drive wheels. Always pay attention to these when installing tires. Changing tires, especially tubeless tires, is best left to the experts.

Brake system

Only for experts!
Amateurs should fundamentally leave the brake system alone. This goes for changing the brake pads as well as for changing the brake fluid – this must be done after two years at the latest. After four to six years, the brake lines and hoses should be checked and replaced if needed. Draining the air out of the brake hydraulics is also a task for the experts.

Brake fluid can attract water through the finest pores in brake hoses. This lowers the boiling point to a dangerously low level. Or worse: The water in the brake fluid can lead to corrosion. The dirt and sludge produced by this primarily collects in the main brake cylinder and leads to increased wear – to brake failure in the worst case.

Maintenance work

For adjusting the air gap or tightening the timing chain, we recommend visiting a specialized workshop. Carburetor adjustments (synchronization, idle mixture) or bearing lubrication, especially with the steering head bearings or reversing levers of the rear wheel suspension, is also a job for the pros. Changing the fork oil should also be left to the specialists.
