....Yet another suspension question

I have searched and cant seem to find any recomendations for fork springs for my weight and riding style. I am about 165lbs with gear, 5'7" on a '06 950A. I ride very aggressively on gnarly trails and single track. The only reason I slow down for whoops and big jumps is I am tired of hearing the front forks bottom out. I currently have the forks set to the sport setting + 2 turns preload and + 5 clicks comp (from sport setting).

I planned on going with a thicker fork oil and a stiffer spring. I have stock springs right now.

Any idea on spring rate???

Ι think thicker oil will screw up your fast compression dampening.

Wouldn't the first thing to do is measure sag F&R?

I had Konflict Motorsports revalve and spring my 950 after going over the bars last year.
I cant tell you what a difference it made. Alex set my bike up really nice.
If I remember right he used .65 springs
I ride it like a dirt bike and could not be happier.

I'd like to put in a huge plug for Riders Edge Suspension here in BC.

He knows suspension , he knows 9xx's and in one way shape or another he has either done or supplied the valving or springs for every bike in my garage.

I just got to test out his handy work on my 990 a few weeks ago ( along with another buddy on his 990 who also had his done) and as always it was the best money spent.

When you start looking at suspension upgrades you really need to include not just your weight but also your weight in all your gear including any gear like loaded tank bags, etc.

For example, I weigh 185 but after I put on all my gear and add my hydro pak and tank bag I'm now over 225 LBS.

... I did. I'm trying to get a good setting for aggressive off road. Not touring.

At the very most I would say 175 with gear and what not. I'm a little dude man!!!

Sag

ok. Race sag for front is 70mm. Thats with the preload at 9 turns.
Rear sag is 44mm with 6 turns preload. I have stock springs front and back. The rear hops around on washboard stuff. The front bottoms pretty easily if a small jump has a flat landing. At some point Ill send my suspension out to SPS for treatment For now I have budget constraints that limit me to just springs. Im just really tired of hearing CLUNK!

racetech.com has a decent spring calculator. I have used it several times to get me in the zone without a bunch of messing around with different springs.

Be nice if we could get you to try out my bike sometime, I'm nearby. . . and a titch lighter than you, maybe 160 with gear.

I had to change the rear spring, 130 seems much better. For the front, I went .56, I still run the preload all the way in- not necessarily a bad thing, but I think you could probably go .58 or .60 without any problem. I think valving on the fork makes a huge difference, too, but like you say, switching to something heavier (like synthetic ATF) would be a good start.

Not sure what springs to recommend for you, but also increase your fork oil level. I'm running 90mm of space right now and am considering going higher.

Good to know. Thanks. We should ride sometime. I just moved to Pleasanton so I am even closer now.

I just ordered .64's from KTM Twins. I figured I would rather too stiff to avoid bottoming out.

Ill definitely be changing the fluid. ATF seems to be what a lot of people are using.

Does a higher fork oil level increase bottoming resistance?

Thanks everyone for all the replies.
