This book is excellent - Suspension BibleWow, the DVO site is pretty informative on this topic. I actually have a customer's RC3+ in for some tuning right now. He has a Blur LT and the shock has the MM tune. The problem he is having is the rebound speed is too slow, even in the fastest setting. The service dept. is fairly slow right now, so I told him I would happily try to improve the performance.
Even though most of you are working with the RT shock, I've found this thread to be super helpful. I actually have a small stash of shims at home, but for now I might just remove one to see how much of a difference it makes.
I have a question for you guys who are doing this on a more regular basis.....are there any good books out there that I can learn from? I know it's a lot of trial and error if you don't have an engineering degree and a dyno, but those two things aren't gonna happen for me anytime soon, so I was hoping for a "working-man's" approach to this. Years ago, in my brief moto-mechanic career I found a lot of good reading on the moto side, but nothing purely on suspension.
Thanks in advance
