you could start off by setting your sag, with your weight I know your front preload screw will be wound in to max. Do a search there are plenty of threads on this subject. And take it one click at a time till you feel good about the settings

Well, replace both front and rear springs for a start. The front isn't *too* bad, but the back will be way to soft for your weight.

Rear spring is pretty stiff as standard, as it was designed with 2 up riding in mind. The front springs can be changed. Just add a couple of turns to the lock ring on the rear shock. As for rebound and compression he will have to play around with it himself to find whats suits him best.

Maybe you guys have got different spring rates, but I didn't think so. Lets not get high speed compression damping mixed up with the spring rate. Even for a 185lb guy, the rear spring as measured (taken from the race tech website) is too soft. It feels ok, but it's a function of the linkages that makes you think it's ok. Trust me on this one, or don't, simply to a spring rate calc and you'll see for yourself.

The preload (the 14mm nut on the top of your forks) will change your sag, but not the spring rate. At 225 pounds you may require going to a stiffer spring, but ... they are around 1.0kg/mm springs stock, so if you're riding bumpy roads they could be good. Depends on what roads you ride and how hard you brake etc. In essence though, the only way to change the spring rate is to change the spring.
