Advice on adjusting front forks...

I am a completely clueless as to what to do, if anything... My '04 R1 suspension is still set for the factory settings.

I find that the front end feels too "soft" for me (like under heavy breaking, the front dips more than I care for it to).

I don't know if I should even bother adjusting the front (ie. this is normal) or if it would be wise to stiffen it up.

I weigh ~170 lbs.... and ride moderatly aggressive, but not 'track' agressive.

Any suggestions on any settings change, if any?

Thanks,
Aaron

p.s. Pics and/or detailed changes would be great-- I'm not super mechanically inclinded.

Okay... I can see the settings for the '04 R1 on that page (above), BUT I don't know what those columns mean as far as adjustment goes... like..which dampner is what, etc...

I know, I know.. I'm dumb... err.. uneducated. But I really don't know what to adjust w/out pictures or a detailed description on which is what to adjust.

suspension

on the bottom of your forks on the back (toward the rear of the bike) are two little slots for a flat head screwdriver. One on each fork leg. If you turn it to the right it stiffens the front (called preload) and will keep it from diving on you. It will click for each setting of stiffness. I weight 165lbs and my '04 is 3 clicks from full stiff. I had it at 5 clicks from full stiff for the first 5k miles and just stiffened it a bit as the suspension beds in. If you turn it all the way to the right thats called full stiff. turn them both to full stiff and count the clicks. then back them off a few clicks less than stock. You can always set them back to stock if you don't like it. Just make sure you set both of them the same (both 3 clicks off of full stiff, or both 5 clicks or whatever you like).

If it feels firm enough but you don't like the angle of the bike, you can increase the rear preload as well, it will raise the ass end of the bike. That's what the c shaped wrench in your toolkit is for. The rear shock has notches in it for the wrench. Clockwise is loose, counterclockwise is tighter. I tightened mine up two clicks to get the angle that I like.

You might hear guys talk abou rebound also. That's how fast the forks throw the tire back down to the road after you hit a bump. That's the slots at teh top of your forks. HOpe this helps. - Shane

Grab your owners manual and look in there and see which adjustment is what. It's easy

Minor correction. Adjusters at the fork bottoms are for compression, not preload.
