Consideration should be given to componets which may show signs of premature failure and replaced
accordingly.

8.1Inspecting the air filters
To remove the air filters, undo the three M6 bolts securing the rain shield and lift off each carburettor.
Separate and remove the air filter. Wash out the air filter with fuel and then dry with compressed air from
inside to out. Reinstall or replace if necessary.
8.2Inspecting the fuel lines
Check the fuel lines between the diaphragm pump, carburettors and fuel tank for leakages and/or other
damage. Replace leaking and/or damaged fuel lines.
8.3Inspecting pulsation lines
Check the pulsation line between the vacuum nipple on the crankcase and the pulse connection of the fuel ?
diaphragm pump for leakage and/or other damage. Replace the leaking and/or damaged pulsation line.
8.4Spark plugs and sparkplug leads
It is recommended that the spark plugs be checked one after the other to avoid mixing up the sparkplug leads
and their connecting positions.
8.5Inspecting the condition of the sparkplug leads
Remove the sparkplug leads and check the contact socket inside for corrosion. Check the SAE-contact (the
screwed on contact hood) of the sparkplug for corrosion or "deposits". If there is corrosion or "deposits",
replace the sparkplug lead and SAE- contact of the sparkplug (usually here the sparkplug would be
completely exchanged - see next paragraph).
