Good evening and New Year
I purchased a 1972 BMW R75/5 a year and half ago as a project to work on in the winter. The bike was put In to storage, covered in Vaseline till I bought it home.
Pretty much stripped and I am doing a mechanical restoration and thus far all is going as planned. In inspecting the timing chain, it needs to be replaced. This should be simple enough, but before I start stripping the chain off, I went looking for the timing mark on the crank shaft sprocket and the cam shaft gear. Either I am blind or there is none. can someone shed some light on this!
In looking at the crank shaft sprocket I will replace as it seems to have sone wear along with the ball bearing front crank. It was evident its been hitting the inner case on the right side facing forward.
