I have a little bit of oil smoke on occasion if the bike has been parked for a while. This seems to be normal for all BMW bikes that have valves on the low side when on the sidestand. Not concerned about that.
When that happens, I am seeing some of it come out where the exhaust collector is bolted to the engine.
I have no running problems whatsoever, and it isn't loud, so if it is an exhaust leak, it is a minor one.
So, is this something I should muck with? If so, how? Try to tighten bolts, replace gaskets?
