The Intiminators create a difference between static sag in the garage and dynamic sag while riding. The Intiminators exert control over hydraulic damping when the forks are moving, and that control does not exert itself when the forks are not moving. Typically, forks with Intiminators tend to ride higher in the travel while riding. Therefor, Intiminators tend to work better with lighter springs and at different static rider sag settings than what was recommended before Intiminators came along. What do you mean 43 MM (static) rider sag "turns the ride to crap?" If 55 MM static rider sag drops the the front end too low and makes the bike unstable, raise the triple clamps on the forks a bit. If the forks do not bottom out, 55 MM may work good when you raise the triple clamps. If the 55 MM static rider sag causes the forks to bottom out, increase the fork oil or preload a bit. Be careful, track the total travel with a plastic tie on the forks, too much oil can cause the forks to hydro-lock and damage seals. May be a static rider sag of 50 MM and increasing the oil level a bit will be a good compromise. If your shocks are not using all the available travel over the worst bumps you ever hit, maybe reducing shock preload will help. 2.5w oil will also decrease rebound damping, do you want to deal with that? Maybe you need a fork spring one rate higher than stock, not 2 or 3. By their very nature, stiffer springs provide more resistance to compression and also rebound with more force. Therefor, the stiffer springs generally need less hydraulic compression damping and more rebound damping to compensate. Without or without Intimininators, spring rates must match damping curves for a set rider weight.
