ouch! the front isolator on my 97 M2 failed just over a month ago... i caught it and replaced it, but i was warned that the failure might stress the rest of the assembly (bolts, hanger, or head). well, it did... on my way to work this morning my bike went from happy to sad in a fraction of a second: the left bolt sheared off between the hanger and head and the right bolt tore a big chunk out of the head itself. thank god for the tie bars or the engine would've nose dived right into the street! anyway, i'm calling this an "opportunity" to upgrade to thunderstorm heads and pistons, but i'm wondering about the hanger... i know front mount failures have been discussed, ad nauseam, but i'm not getting a clear picture of hanger durability after the fact... mine is intact, but how much stress has it gone through? the mechanic didn't mention replacing the hanger, but i think i trust the opinions of the members of this forum than the opinion of most mechanics!

I'm wondering a bit too. I have a 97 S1WL, and have never replaced any of the isolators, and the bike vibrates a LOT; MUCH more than a new 1200, which I found vibe free. I'm wondering if I should just update all three, as I assume they've hardened (low humidity colorado) in the last 8 years. Overload in Colorado | ||

May I suggest going with XB heads instead of the T-storm. The XB heads are supposed to flow better than the T-storms, and be a better starting point for performance. Don't know what the deal is as far as needing to change pistons. You'll surely have to change pistons to use T-storm heads though. And ... using XB heads will give you a good excuse to get one of the nice front mounts from NRHS  Henrik | ||

Over -- new isolators will reduce the vibes, improve the handling, and get your dainty unmentionables whiter that white . . . low humidity may or may not affect the rubber (I really don't know), but the crud in the air will, and the 7 or 8 years fo vibes will certainly have fatigued the mounts -- not a lot of dough, and the effort, while not inconsiderable, is within the realm of reasonable, for the payoff, and doable -- schedule a weekend, get a buddy to assist, and enjoy the task at hand |
