Re: Stuck ignition switch

WD-40 is great for drilling,taping,machining, aluminum.

Re: Oil in cylinders

The cylinders and pistons need to be pulled and inspected.

Re: 1977 R75/7 sat for for too long

It can be bored to fit 800cc pistons. You may want to check the availability and price. Used 800cc cylinder assys. from those that have converted to 1000cc may be available. Look around.

Re: R75/6 crosspipe

" I make the assumption that BMW knew what they were doing when designing in the intake and exhaust systems for engine performance. YMMV." The R 50/5 and the R100rs had exactly the same part number exhaust head pipes. How can an engine half the size of the other have an exhaust system designed for p...
