Hello,
I am working on a friends 1971 R50/5. It sat for 3 years. The mileage is unknown. It's the old "ran when parked" story. So I have never heard it run. I have performed the following:
points, condenser, plugs and plug wires, all fluids, new positive and negative battery cables, rebuilt carbs, new battery, and I cleaned up electrical connections and adjusted the valves.
It won't start. I have a nice blue spark, and fresh fuel. It has only 70 psi. compression on both sides. I know this is really bad, but I have had other bikes that ran with less (not BMW's).
Your thoughts? Thanks in advance.
