kickstart pinion /bush clearance

[oldbikerbill]

I've been having some difficulties with my kickstart lever crashing to the floor when I use it.  The pinion gear and ratchet both look good and I bought a new bushing from Klempf's, but when I put the pinion on there seems like a lot of wobble.  Does anyone know what the clearance between the gear and  the bush should be?  I tried to find an on line workshop manual but no luck.  Thanks

G'day Bill.
There were some dodgy pinions going around a while back and needed a bigger bush (I got one). I complained and a new larger bush was sent. It was a while back and I can't remember who the supplier was. If I had to make one I'd give it 1+ but no more than 2 thou".
Cheers

Hello Bill,

Pre 1954 and later gearboxes has different ratchets and bushes. The teeth profiles are different and early bush outer diameter is bigger than late´s. Check that You have the right bush. Most British and U.S. dealers do not know the difference but in the Continent they do:
