Oil and filter change

Hi ppl,

Do you know that engine oil takes a terrific amount of abuse and must be changed regularly to ensure engine longevity.Follow these steps to safeguard your engine.

  • Remove the drain plug from the sump and drain the old oil into a drain tray. Check that the drain plug washer is OK then refit the drain plug.
  • Unscrew the old oil filter and thread the new filter into place. Dispose of the old filter.

Air filter
You have to take a look at airfilter also.Air filter is either a paper or foam type air filter element will be fitted. This element can be cleaned, but if it is very dirty or damaged its better to fit a new one.

  • You can tap the paper element to dislodge dust.
  • Foam elements need to be washed in solvent, then dried and re-oiled.

Spark plugs
The spark plugs will wear over a period of time and the gap between their electrodes will go out of adjustment. There will also be a build up of deposits on their firing ends due to the combustion process - renew the plugs if they are dirty of badly corroded.

  • Measure the spark plug gaps with a feeler gauge.
  • Adjust the gap by bending the side electrode only.

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

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

Oiling cables, levers and pivots
Cables, stand and lever pivots are exposed to the elements and 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.

Clutch
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.

Engine idle speed
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.


Brake pads
It is important to keep an eye on the amount of brake pad friction material because it will eventually wear down to a low level; at this point the pads must be renewed.

  • 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 the pad material can't be seen clearly, the pads must be removed from the caliper for examination.
