Thanks for the replies. The front tire wear is perfect, there are nice 1" thick unworn strips on each side of the bald center, so I'd say that's all good. Hahahaha, I had to throw that one in there.....anyways, I'm j/k. But seriously the tires are wearing evenly. I do think the shock oil may be the most logical culprit, since it doesn't matter what the valving is set to if its working in a piss-thin fluid environment it won't be able to do its job at all. I'm with you though, Murdock, I don't know about changing the spring rates. Preload is a different story, though. I'll try changing the oil and see what happens. I should let Tom ride it, but he may fall asleep on it cause of the lack of an extra 150hp.
