FWIW, the shock from the 04' helped a lot. The gas in the 02 shock was gone, so it was going from no dampening to some, and also a better spring.
I get the desire to leave things to the professionals, but I think it's a bit misguided here. Most shops in my area, and it's a big wealthy area, have no idea about the particular weirdnesses of the 919, and ultimately they're not riding it, you are. I find it foolish to forgo some research on how the thing works when it's your ass on the line, though of course you shouldn't assume any particular job is as easy at it looks on the internet. That's the point of this forum, yes? Otherwise it would be a static page that would say "Try to find a mechanic who knows what these bikes are."
My suspicion for mine is that I probably will go into a shop in the city to have the rear suspension tuned to me, now that I have one that can be tuned. I just picked up a suite of cases which are in Lake Co, about 2-2.5 hours on the 919, and I suspect some of those dollars will go towards a fork rebuild, too. I'll report back once I do that, and see how it feels.
