Amazing how these forums prompt the mind, I had exactly the same issue with fogging under the instrument lights cover within a couple of weeks of picking up the sport. (Seemed to fade into insignificance when compared to warped rotors, broken exhaust bracket, tint coming off fork tubes, and not to mention leaking carc (yes that’s still going on – Pete I’ll definitely be bring the bike down within the month and I’ll get the 40,000K service done at the same time).
Anyway if your having the fogging issue, may I suggest that before getting the drill out, taking the instruments apart, be patient.
Fogging stopped after a couple of months by itself. Don’t know why, must be “whitemans magic”; In the past 18 months or so, it’s never occurred again, the bike still gets washed, ridden in the rain and has travelled many miles from sea level, over the mountains along the Great Divide, without a problem.
Anyway least the post started me thinking, there’s another issue that Sport owners best be aware of, that is the light frame on the fairing breaks (plastic welds crack). I’ll post another topic with pic’s, fix etc.
