I just bought an 01 426 yesterday. The bike runs and rides great. My question is, what should be coming out of the engine vent tube? (the big one from the top of the head that runs down along the left side of the frame) There seems to be a small amount of oil coming out (fine spray) but it seems a little milky. This morning I ran my finger along the outlet of the tube and picked up what looked to be antifreeze with a little oil on my finger What could this be? I hope there is nothing wrong. Thanks for the help.
