I took my bike to RMR and I'm actually surprised I don't hear about them constantly on here (although I was referred to them from friends on here). The guys seriously know their shit. Obviously my stock suspension isn't near good enough to have them set it up perfect for me riding 2-up with my gf but they adjusted it best they could with the Showa's I have on the bike and told me what I need to do to get the best out of my riding ability and the bike (which obviously results in $$$).
But seriously. Run down to www.rmrsuspensions.com and pay $40 to have them adjust your suspension for you. Even with the shitty shocks I have on my bike (yes, for some reason an 05 top of the line Duc comes with shit shocks) they made a serious improvement which should tide me over until the Ohlins come...
$40 is nothing compared to what it can do for your riding, and they explain what they're doing, not just banging shit around.
Call them, all the cool kids are doing it.
