I was going to do the same, but have what is apparently a common Concours problem, a leaking o-ring somewhere on the head or valve cover.
Mine doesn't drip, but there's a dirt and oil mess on the front and sides of the block and cases.
Since I'm doing a full exhaust and coolant flush, that should give me more room to work.
It's been very hot and humid here anyway, too much for enjoyable riding.
I got the ecu flashed with an air/fuel tune for the exhaust too, and the stock header has cats, and the muffler is pretty restrictive, so I ended up being better off doing it all now.
I'm debating on a valve check, injector cleaning and throttle body sync.
But I don't know if I want to do that now, or wait for colder weather, but I ride year round anyway.
