The following is a sample of text from the competition section of this manual:

Check that all the nuts and bolts are tight. Use box spanners. The engine should be run warm when carrying out these checks. Listen for any unusual noise or knocking both at low speed and high speed, and when the engine is under load in high gear.
The most usual cause of engine knocking is incorrect ignition timing and overheating. In order to avoid engine seizure or unnecessary piston wear, any signs of knocking must be corrected immediately. Other noises (squeaks) can be a result of piston wear or play in the big-end and main bearings. Noise can also occur due to wear on the throttle or carburetor body. Feel around the cylinder head with the hand to find whether there is any gas leakage. When checking the tightness of the cylinder head studs, always use a box spanner. Check the idling speed. For adjusting, see the instruction in the Owner’s Manual. Tighten all the engine mounting bolts.
Remove the air filter, clean it and put new oil in it. See page 30. This must be done before each competition.
Check the tightness of the air cleaner on the frame and its sealing against the carburetor.
Clean the outside of the carburetor if necessary.
Tighten the screws on the reed valve housing. Check the tightness of the carburetor on the valve housing.
Adjust the carburetor. See page 28.
Check that the throttle control handle can move easily at full handlebar lock on both sides and that the engine speed is not altered due to any tension in the cable. The cable must not be attached to the frame with insulating tape or similar but should be completely free between the carburetor and throttle control handle.

Check that:
The tank does not leak.
The tank cap docs not leak.
The fuel cock does not leak.
The fuel cock strainer is not blocked up.
The fuel lines are undamaged and do not leak.
