I foolishly cleaned out my cookies before verifying my username and password...and couldn't get back in here again.
This is going to sound really, really stupid, but...does anyone remember my username? I'm Derek Mathias, I own a supercharged Valkyrie in addition to a 2000 XX, had a friend who crashed my XX (but it got better), I have only been posting a few times in the past few months, and the last time I posted it was describing my problem with tank-slapping vibration at high speed. Ring any bells? I THINK the username was "Underling" but I have so many accounts I'm not sure. However, Underling isn't working. Hmmm. Can you spell amnesia?
Anyway, as for the tank-slapping problem, it turns out Hare Racing set the sag on my XX's new Racetech fork kit to 2.5". Ack! No wonder behavior was screwed up! Once they fixed that, high speed vibe went away...and was replaced by a very specific slow wobble only when decelerating between 50 and 45 mph. Nothing serious, just annoying.
Sick of it all, I took my XX to Lindeman Engineering, supposedly one of the best suspension companies in the US. They took almost twice as long as they'd quoted, ripped out and replaced the Racetechs as being entirely inadequate pieces of crap with a too-weak spring, adjusted the Penske shock which was supposedly 10 cm longer than the stock shock, and basically set me up with a killer suspension adjustment for $750. Felt great as I rode off...until I decelerated between 50 and 45 mph and got the EXACT SAME wobble. Ack!
Well, to their credit, they said they'd do their best to get it right, and refund my $ if they can't get it right.
Well, hopefully perfection is the journey, not the goal, or else I'm screwed. ;-)
