I think the pin was an M20 fine thread but Iím too lazy to go to the shed.

Stein Dinse have the online parts listing or Greg benderís page would list bearing part numbers
850 T3
850 LeMans killer goose or somesutch Iím told
850 LeMans
850 LeMans II (I've butchered it by fitting a round headlight & removing the front faring.)
SP1000 Stucchi
V11 Ballabio
V7 Sport (needs a little work)

The thread is M20-1.0. I bought a pair of taps on Amazon for under $20.

The bearing is trade number 30203, which 17 x 40 x 12.

Do I recollect wrongly, or isn't that the same as the crank sludge trap plug?
