Valve Shimming service (no maths required)

Let us take the hassel out of re-shimming your valves.Just provide us with  your valve clearance measurments, and the size of your old shims, and we will send you new shims of the correct size by return of post. If the sizes on your old shims  are not readable, then just send them to us, labeling whether inlet or exhaust, and we will measure them and send them back with the correctly sized new ones.

Valve Clearances

         

It is VERY important for the valve clearances to be set correctly, and for that clearance to be maintained for consistent performance and maximum component life.  A tight valve clearance is more likely to burn the valve due to combustion gases leaking past under high pressures.  A loose valve causes the valve seat and valve sealing face to wear due to excessive valve closing velocities.  when setting up the engine its important to get the clearances as close to perfect as possible and then maintain those clearances.

At Zoom Factory we use shims from HotCams in the USA, we find they represent excellent quality and value for money. And at only £ 3.oo per shim it makes keeping on top of important maintainance a whole lot easier.
