Fork preload and compression adjustment

Hey guys, been redoing my fork seals and cleaning up the forks. Just curious as to what your settings for the pre load adjuster and bottom compression are? I'm a pretty big boy, and my air gap is around 112mm, with 10w suspension oil, I cant seem to find the default factory setting in the shop manual or the haynes manual. Also if anyones curious in the first picture my dad made a wood lathe out of wood hahahaha

Re: Fork preload and compression adjustment

Bump anyone? I understand there is a procedure concerning rider sag, I was just curious if there was a default setting I could base my adjustments off of.

Re: Fork preload and compression adjustment

Since you're doing fork seals, why not update the springs? Racetech's website has a spring calculator, you can input your bike (I don't see it listed)and your weight and it will recommend a spring rate for you.

You may want to a also have a look at the rear spring rate also.

I saw a really big guy the other night on a GSXR. He had an extended swingarm and a shorty exhaust, but was obviously using the stock springs. It was a sad sight to see. He had no idea how unsafe that bike was for him to ride like that.

Re: Fork preload and compression adjustment

Here's a Sport Rider recommendation. These are only a suggestion. I see you said you're a big dude, so unless you've replaced your OEM springs with some 1.0's or stiffer the front will still feel squishy, and you won't get the proper sag. My 96-99 manual has a suggested initial setting for the adjustments as well in the beginning of the manual, I just don't have a picture of it. This article only includes the 96-97, but here's the link anyway:
