 Valve Clearance Setting Guide
Thread Started on May 1, 2006, 11:15am

Setting the valve clearances are quite straight forward, the valves should be set when the engine is cold, and when the engine is at TDC (Top Dead Centre). TDC can be set by turning the fly wheel until the timing marks line up. i.e. the 'T' is aligned with the pointer on the engine case.

Then remove the cylinder head cover and ensure the camshaft timing marks are ligned up with the edge of the engine casing (red arrows), with the large hole in the cog away from the engine(yellow arrow)

With the timing now set, and the head cover removed you will have access to the tappets (used to adjust the clearances). The tappets are made up of an adjuster and a lock nut.

To set the gap we have to loosen the lock nut, set the adjuster using a feeler gauge, and then tighten the lock nut WITHOUT moving the adjuster. The gap should be set to 0.05mm for both inlet and exhaust valves.

If you have a scooter problem, and no one else can help, if you can find them, maybe you could hire the A-Team!
