I just picked up and installed an '01 Shiver. It's old but in great condition and works pretty darn well. Just not sure if I'm running the right springs. It's got the stock springs in it and I'm running 10wt oil to get the damping close to what I'm used to. I weigh 80kgs (or 175lbs in US-speak). What springs do others run? I'm considering getting one softer spring.
