Post Setting Up Suspesion

I have visited many sites on the proper way to set up your suspension for the road or track.

I removed my Olins front springs and put back in my stock ones because the race springs were just to stiff for the road........(DUUUUHHH!)

Most of the sites tell you that you want 30 to 35 mm of sag in the front and rear, my questions is I am only 5'9" 165lbs and if i follow this formula I would have my front end backed all the way out(meaning the softest setting) I know that it is rider preference.

Give me some opinions on how you do it and how it has worked out.

While I don't track I do love to play with the settings. There is no "right or wrong" setting.
I prefer a really stiff ride, and I'm only 6' and 155 lbs. I don't like a lot of movement through the corners, so I have my compression set stiff, and my rebound just slightly more.

like Zero, i do like the ride on the stiffer side of things. my compression is set pretty stiff, but my rebound is a little on the softer side. there are so many little bumps around here, that it's difficult to go with a nice, stiff stance on the bike. i've seen plenty of guys overcompensate the rebound damping on their bikes, and they hit bumps in corners, and the rear wheel just hops all over the place. you need more compression than rebound.

Best thing to do IMO is have a pro suspension guy do it and should cost ~$40.

a pro suspension guys' opinion and his could differ.. it's about what feels good. not what the suspension guy says is right.

^Exactly. What highlights from the TT races, and you'll have your answer to the bottoming out question. They'll do it many times a race, and even scrape their fairings. If you're just riding on the street and that's happening, something's really wrong, and should be fixed.

Remember when setting up suspension to wear all of your riding gear. Unless you have a front wheel chock and a buddy, I suggest also taking it to a suspension pro as well. Unless you have 2 extra pairs of hands to help out, 1 to hold the bike up and 1 to measure. The pro guy will most likely setup ur suspension for road, since you're not at the track for them to setup properly after a few laps.

As far as setting sag, I would aim closer to 30mm for road, and even more, say 25mm for track. Front sag can usually be a little more sag than rear. As far as rebound just remember that the bike should evenly rebound. That is when you stand to the side of your bike and press down at the tripple tree and seat, your bike should equally dip down and rebound at both ends as evenly as possible.

Thats just kind of a general setup, then adjust from there for your road conditions and prefference.

Vangil, if the fork seals are blown, you don't necessarily have to replace springs. If anything just the seals and oil, and maybe the valves. And do both forks at the same time, not just the one with the blown seal. Once those are replaced, you're forks will feel alot better. Also make sure your forks are not bent, which may lead to another blown seal.

I'm no suspension pro, just my 2 cent.

no need for new springs. just get seals, bushings and sliders
