Servicing tips for your motorcycles

There should be a certain amount of slack in the drive chain – usually about 30mm, but check your handbook. The chain will stretch with use and you should take up the excess slack with the chain adjusters at the ends of the swingarm.

1. Measure the total amount of slack in the drive chain at a point midway between the sprockets on the lower run of chain.
2. If you need to adjust the chain tension, slacken the rear axle nut.
3. Use the adjusters on the ends of the swingarm to adjust chain tension. Adjust each one by the same amount.
4. Check that the wheel alignment marks are the same on each side, and then tighten the rear axle nut.

Because cables, stand and lever pivots are exposed to the elements, they must be lubed regularly to ensure smooth operation. Apply a few drops of light oil or an aerosol lubricant to the exposed ends of cables, the handlebar lever pivots, brake pedal and gearchange lever pivots and the stand pivots.

Correct adjustment of the clutch is important to ensure smooth gear changes and prevent clutch slip or drag. Most clutches are cable operated and will have a threaded adjuster and locknut at each end to set freeplay.

Check that the engine idles at the correct speed when it is fully warmed up. There is usually an idle speed adjuster knob at the side of the carburettors.

Your brake pad friction material will eventually wear down to a low level, at which point the pads must be renewed. You can view the pad material via the mouth of the caliper. Most pads have wear indicator grooves, cutouts or a line to indicate the limit of wear. If you can’t see the pad material clearly, the pads must be removed from the caliper for examination.
