I thought you were looking of a black one (i.e., '08 or '09). I can't blame you for looking for an '06, though -- a Gen.II that is a pretty (and fast) blue.
I've never really understood all the complaining about heat from this bike from people that don't live in hot, humid southern climates. It just hasn't been a problem for me in the 5 years I've owned mine in northern Nevada and over here 1200 feet above Sacramento. I've seldom been bothered by it, though I recall a brutal few days of riding when it was hitting 110+ for over a week here in the summer of '06.
There are a few things you can do to moderate the heat some on a Gen.I, if it bothers you. Smitty here used to make a heat blanket that would fit under the tank (I had one, but the mechanics destroyed or lost it when mine was de-ticked last summer, so I'd like to get another). That helps a little, though I'm not sure it's that dramatic an improvement. A search should also yield a variety of creative "fixes" that are reported to be slightly to moderately effective and a LOT of threads on it.
I always ride with protective gear, but if I rode in shorts during the summer, I suspect that I'd really notice the heat on my crotch and legs (at least, once the gas in the tank heated up). I don't see how Gen.I heat is likely ever to be an issue riding on the coast. Maybe a different story if you venture over here into the interior or decide that the desert is an optimum summer destination. I'll also grant that riding across Nevada and Utah in July during the day is likely to present a heat issue, as is being stuck in traffic in Bakersfield in early August. But even the Gen.IIs are not like having air conditioning in those situations.
Bottom line is that I wouldn't let heat complaints sway me away from a great bike in the Gen. Is -- they are selling at real bargain prices right now.
