Original wheels

There is a product which will kill the rust, stabilise and seal the surface, you can then fill the holes and proceed to spoking, truing the rim and fitting to an original drum if the wall thickness will allow setting up and machining to the radius of new bonded brake linings. Before you spoke get th...

John, the issue you will find

John, the issue you will find with an original wheel are age issues. They have rolled rims, you can't soak them in any rust killing fluids and the interior of the rolled rim will need treating.

Engine stamps

Bosch JN7 Rucklicht Lense

And most importantly the Bosch Trade Mark shows the early ...

Yes it should have a filter,

Yes it should have a filter, I had an original fuel tap with my R51, and it had a filter. Sounds like yours may not be correct for the bike?

My reason for asking is to try to work out what the gearing is in my Veigel Tachometer, as the dial plate is a marriage to the case. In other words the dial plate is a...
