Bill: Thanks for the pic. Water would have to run uphill for the coolant to get from that weep hole to the bolt I mentioned. When bike is parked (on a wheel chock to keep it vertical), the bottom of the rear wheel is about two inches above the bottom of the front wheel. When I get time, going to run the bike "in place", and track down the leak source. Probably something simple up above the engine and I just am not seeing it. Will post back when I find it.
