Title: 2003 F4i suspension setup
Post by: MotoPutz on May 25, 2008, 08:56:15 PM
Ok, so I finally got around to starting to setup my suspension (setting my sag). I have the new .95 springs in the forks which is what race tech said I should be running. After all the reading I have been doing I am trying to set the front sag to 30-35mm and the rear to 25-30mm. I had my rear a tad too stiff so I backed it our a couple turns and I have it right where I need it. But my front I now have unloaded as much as I possibly can and its still only at 26mm. Now I admit I don't have my gear on when I did all these measurements but I wouldn't think it would make that much difference. Some of the stuff I have read says racers use 25-30mm in the front but I'm not a fast aggressive rider yet.

Is this going to cause much of an issue? Will the spring loosen over time a little? (break in)

i have read that your fork sag should be 1/3 of total fork travel. ie 150mm fork travel, sag should be 50mm(just an example) to get you into the ball park sag setting. this may be wrong but i have heared it from a few different sources. if you race and are worried about cutting lap time by a second than finer tuning would prolly be needed.

26 is not enough.

Are you saying you backed out the preload adjusters all the way and you still don't have enough sag? Then I think the next step would be to adjust the length of the preload spacers.

I put .95 springs in my F4i and I just ride it. Never set the sag at either end. :(

Do I need to add preload spacers or remove one or two? Does anyone want to help me with this? I am good in a garage but I have never been in my forks yet... Not to mention I don't even have a garage to work in.

You should have set up new preload spacers when you put the springs in. The stock spacers won't work.

I had Jay at BVH do the work but I know the new springs came with new shims, I'm going to assume he put them all in, so does that mean I need to take one out of each side? I'm not sure what will equate to adding more sag.

That wasn't a helpful comment.

Not to meantion that more hamburgers would mean more sag which is what I need.

Maybe if I mount your ego on my triple clamps I will have enough wieght to get the sag I want...

So can the shim stack be adjusted? or do I just need to get .90 springs...
