Pulley Shim 1.3mm Front Outer Pulley 125-300cc.

£3.00

This shim goes against the variator tube / inside the recess of the front pulley. 

2t & 4t 125-300cc  

These are a tad thicker than normal... ideal for belt shimming / helping with crank thread spacing. ( standard is 1mm ) 

some later 125-300cc 4t engines use 1.3 as standard.
