My only response to that would be...you have a 103" motor, and I'm sure you've ridden it around town a lot. Has it ever leaked? I've got 22K on my 06 103, and I've had it in temps of 100 degrees, sitting at a redlight, and it's never leaked (knock on wood). So I'm not buying his rationale...not saying the guy is intentionaly not being truthful, but is just grabbing at straws. I would also wonder how many 110's he's seen with some real miles on them.
If you like the red SERK (it IS a beautiful bike, as I've seen at least two of our member's bikes), get it, but just be prepared to have some down time occasionally, buy the extended warranty, and enjoy the bike. With the new attention being drawn to the issue, and some of the 07's approaching warranty expiration, perhaps HD will be forced at some point to do something about this situation.
Or, buy a set of blank tins, have them painted like you want, store the CVO tins off the gold bike, put a cam and some headwork in the 103, and have the best of all worlds.
