Hey Bill, now that's interesting. I guess our bikes came from the same batch huh?
Now either they used a bunch of gaskets which were not quite right but which would do the job ok, or the gasket blows out under some kind of pressure, or the same slacker who assembled my bike also assembled yours.....
The fact that you haven't lost any oil from it, and that I only lost oil on one occasion, leads me to make a connection I didn't make previously. The ride when I lost the oil was the same ride as when I dropped the bike onto its right side. I was stationary and lost balance and the bike wound up resting on the brake pedal I guess - not so far that I couldn't haul it back up with a bit of brute force and cussing, but far enough maybe to allow oil to get into that part of the engine - the breather chamber apparently. This is the only thing I can think of to explain the oil leak only happening once. At least it led to the discovery of the dodgy gasket
Mine too gets a little lumpy ticking over sometimes, but nothing bothersome. Let me know what the service guy says about the gasket - I'm probably going to wait until I've done the three hundred miles before I take mine in.
