42 rear spring you need to stiffen comp up but you should be far off on sag with a 42. Also with your heihht, you might like a 48.
98mm sag and 138psi is so far, something is not right in the post above.
But part of the reason this works for me is because I’m an over the back of the bike rider.
When testing suspension settings, find a decent baseline setting. Compare against that baseline (and this is key) wrote your thoughts on a notepad if you aren’t great at remembering what you like. Enjoy!

At your weight I would start at 150psi and work up. Sag on stock stuff should be 105, I think you may be past the suggested preload on the stock spring.
107mm sag, bike does not turn (understeers)
102mm sag bike does not turn (oversteers, but feel like understeer)
98mm sag bike turns, but suspension feels like shit
105 sag, bike turns, suspension feels good.
Same with fork air pressure, 180-200lbs:
165psi, bike does not turn (understeers)
140psi sag bike does not turn (oversteers, but feel like understeer)
135psi sag bike turns, but suspension feels like shit
150psi, bike turns, suspension feels good.
This doesn't apply directly to you but I weigh 155 and ride a 250sx. The stock pressure on the fork is 148 but I went softer on the rear spring and have always run 141-143 psi in the fork. Enzo just had my suspension recently and recommended 142-145.
I’m 170 lb / 5-11 and can’t get this damn thing to handle. Initially I was standing up in every corner. Now I’m dabbing my foot and walking and it’s infuriating. I can never get this fuckin thing to settle into a corner. And the Front end is so harsh in the chop. just losing my mind. I’ve made some great headway but I’m bout to say fuck it and go back to a Yamaha.
Ive got it now where I have no idea how I was riding the thing at regionals. But it’s still bizarre.
Bars rolled back parallel with forks.
Fork 3rd line.
105 sag
9 out compression
9 out rebound
I’ve never ran settings this fucked up in my Life, bike is better but still bad.
Wondering if I need to up the shock spring rate and get the pro circuit linkage.
