I am happy with the following settings: fork, 12 clicks out on both compression and rebound, 138 psi. Shock, hi-speed compression- 1 1/2 turns out, compression- 12 clicks out, rebound- 10 clicks out, rider sag - 98mm. (Note that the suspension gets even better with time, I liked mine best after 20+ hours of use)

45 rear spring, 105 sag, 15c 15r, 1.5-2.0hsc. Fork 148-155psi, second line, 15C 12-15r.
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.

Im 210lbs without equipment on a 18' FC350. I have the recommended 48 rear spring on and put the recommended 10.8 Bar (156.7 PSI) in the fork. Works great for me, I am an intermediate on the track.

The reason I prefer this of the three posts made here- I feel running a little less air and a little higher compression click on the fork gives the bike and overall plush feel.

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!

I'm the same weight with the same rear spring and I run close to the same pressure(155psi). 105mm sag. Fork at the 2nd line. I do have the Mxtech midvalve and revalve though.

I'm going to try some of the configurations that you give me ... I have it now at 130 psi and I always press everything to the maximum and then release the clicks .. front 9c 12r and back 1.5 and 13c and 12r.

130 psi? I wouldn't do that

I found it that way when I bought it. I'm usually on dry tracks and hard maybe I should make them harder?

This!

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.

Suspension can be deceiving in a way, example:

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.

put a zip tie on the forks and run whatever pressure keeps you an inch and half of travel (35-40mm) from bottoming. Then Turn your clickers . Set air pressure first. 2psi represents roughly one spring rate. That being said, I have run 135-158 in mine for different situations. Im 180lbs without gear. I do recommend playing with air pressure first though.

Like the others said I'd start in the area of 150psi for your weight.

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.

Anyone still ride these bikes? Any decent settings you’ve found / parts that are a must ?

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.
