dont you know the rules, if you have a 06 by law you must trash the 07s and 08s. if you have a 07 trash talk the 08s first an so on. get with the peogram.
Excessive heat as compared to earlier years (the difference in engine heat between my '03 and '06 is noticeable) and the injectors before the upgrade; but by '06 the TC 88 was pretty much being refined including the injectors, etc., so you won't see too many people complaining I don't think.
I know I can't with my '06 RKC. It's a champ and it'll be the last bike I ever own.
