Hi,
Just a question out of curiosity. I have an 87 K75 which smokes if left on the sidestand for any length of time. I know this model predates the change by BMW which pinned the rings to prevent the ring gaps from lining up and allowing oil to seep into the combustion chamber (08/88).
Is it possible to replace the rings or pistons on the early models with pistons / rings from later models to eliminate this behaviour? If so, which is it -- just rings / just pistons / both? Is it a straight forward job or is it a labor intensive job?
Thanks for satisfying my curiosity.
