After reading the thread, I'm taking it that the CR8EHIX-9 are the correct iridium plugs? I'm thinking to change mine out soon, and deciding whether to go stock or not. The bike seems a little slow to start, and by that I mean the starter has to turn over more than it should to get the bike started. Since I've no idea when the last real maintenance was done, I'll do it myself. Since I know my limitations, I'm trying to find somewhere to get the valves checked/adjusted. My local Honda shop is fairly useless, and I only go to them for accessories and parts I'm in a hurry for.
Interestingly enough, seems the heat issue with the 13s is like the "Connie vibe" issue with the Concours 10s. Some people seems to feel it more than others, or some bikes don't have it as bad. Seems to depend on your POV. I have a 2003, and so far, I'm not noticing a heat issue. Don't recall much of one on my '04. It hasn't been terribly hot here since I got the bike in Feb, maybe mid 80's, and I haven't looked up under the plastic much yet, so no telling if the PO has done any heat control mods.
