Front shock adjust on gsxr 1000

I'm working on a 2005 suzuki gsxr 1000, the previous owner adjusted the stock shocks on it to drop it down about an inch, i'm now trying to get it set back up to stock height and was wondering if anyone could tell me how the adjustment screws work or how you adjust the front shocks. Any help is appreciated.

First off they are forks. Secondly you need to take it to someone that knows suspension and get the front and rear suspension "sagged" for you.

The front forks are adjustable for rebound (small regular slotted adjuster on top of the fork cap on some models and at the base of the fork leg on others...) and spring preload (larger threaded hex adjuster found on top of the forks). You can also vary the front end height by loosening the forks in the triple clamps and sliding the tube itself up in the clamps. This was probably something a shorter rider would do to effectively lower the front of the bike. Racers typically use this as a inexpensive or last ditch option to adjust rake/trail when using a larger diameter front tire.

If you have a front stand and know that the front forks have been slid up one inche then you can support the front of the bike and loosen the forks in the tripple clamps (best with front wheel and brakes off) and slide the forks down in the clamps one inch. Doing this will likely change the spring pre load requirements as your ride height will be taller in the front and carrying less overall weight.

One change typically effects all adjustments some what so you want to adjust everything in order (ride height, spring preload, rebound damping) and it is best if you have someone experienced with this set up or your bike will handle like crap...

If you want Jason,I have the service manual for that bike in my data base and can send it to you if you pm me your email address. If I understand you correctly,the guy raised the forks in the triple clamps about an inch. To do that and have any chance of having a ridable bike,he must have also lowered the rear using aftermarket links. Please check for these and get back to me. If I have misunderstood you and the previous owner merely turned the preload adjuster all the way out,the stock setting is 4 lines showing. There is also a suspension link on this forum somewhere that give you the basic starting point. If you want to do this yourself,I'll be more than happy to help you get it set up. We'll probably have to do it thru email 'cause I'll need pics to see where you're starting from. Anyway,let me know which situation you have and I'll try to help you.
