Pre-load adjust on Manitou Black?

I've got an '05 Stumpy FSR Comp, with OEM Manitou Black fork. Not a bad ride, but I'd like to reduce the activity of the fork on everything but he bigger hits. Right now I find it too active. I'm a bigger guy, (6'4", 230lbs) and it's an XL ride. My instinct is to pump up the preload higher, but I don't think that the Manitou has an air preload. Or at least I haven't found it yet.

Any mechanics secrets on how to make the fork less active?

Thanks in advance.

Go to your LBS and have them find you a heavy spring kit and see if they can get you a damper assembly upgrade kit. Both of these things are super easy to install. I did these two things to my oem Black fork and it made a huge difference in the ride.

You should also be able to download a manual for the fork from Manitou's web site here:
Should have part numbers for spring kits and maybe damper kits so you can help your LBS order the right thing.

air preload-increase pressure.

ALOX-On the simple air forks I have had, the only way to increase preload was to increase the initial air pressure.Of course, this decreased sag, but it was supposed to.
I have a Black elite-strictly coil spring- and it has a preload adj.If it didn't I could probably stick some washers in it to preload it.
If it has a coil spring,just get a stiffer spring kit like old fart says.
If it is all air, then you can usually find a stiffer damping kit-just as old fart suggests.
If you are a cheapskate, you can just get some much thicker fork oil.Find out what it takes normally and go up 10 points.Motorcycle fork oil will work fine.Dump the old fork oil,put in the thick stuff-instant increase in damping.
Adding air is free-putting in thicker fork oil is cheap.A spring kit and damper kit are nicer, of course.Luck,Charlie
