@trolle: Very nice bike! You are a lucky guy because you have a warm and clean workshop!
I envy about you.
@Steve Hawkins: I don´t know what milage is on the R100. But what I know is that nobody loved the bike before.
There was no clearance between the exhaust valve and the rocker of the of the right cylinder. So the ventile never closed correctly. The second point is the condition of the carbs. I don´t believe that they worked as they should.



I replaced everything inside the carbs.


I found the A.T.E . brakes in this condition:




Those are the same calipers. I only cleaned them

The wheel bearings looked like that.

I´m sure the R100 has never had any services or maintenance. This is the old air filter.

I hope I will get her back on the road again.
