    Forks bottoming out

    Hi guys,some help please
    I've recently rebuilt the forks on my 83 GSX750ESD. The forks are actually off a Katana of the same year(different anti-dive).
    The problem is that they are bottoming out under hard braking when going over bumps in the road.
    How can I stiffen them up.
    I did the rebuild in accordance with the factory manual but it seems just too soft.
    Thanks

        IHAVE NEVER DONE IT I JUST INSTALLED PROGRESSIVE SPRINGS BUT--THERE ARE 3 SPACERS WITH WITH PROGRESSIVE KIT -THIS LEADS ME TO BELIEVE THAT YOU CAN CHANGE THE LENGTH OF THE STOCK SPACER AND GET BETTER SPRING TESION--MY FAVORITE WRENCH TOLD ME ONCE THAT THEY USED WHAT LOOKED LIKE A PIECE OF PVC PIPE AS A SPACER AND THE TENSION COULD BE INCREASED BY USING A LONGER PIECE OF PVC THAT
        WAS ABOUT THE SAME DIAMETER--ALSO, I HAVE SEEN THIS DISCUSSION A FEW TIMES BEFORE ON THIS WEBSITE AND I AM QUITE SURE THAT OTHERS HAVE ACTUALLY DONE IT --I JUST DONT REMEMBER WHO IT WAS

          Fork oil -- quantity and quality

          Make sure you have the correct amount of fork oil in each. My mechanic uses 20-weight motorcycle-specific fork oil (BelRay brand) exclusively. I recently had him install new seals and fresh oil, and they work great.

          Air pressure. Follow Suzuki's recommendations for air pressure, and make sure this is equal in both forks.

                My brither installed some aftermarket thing on his Kaw that went on top of the fork tubes but it came from a bone yard---BTW why do you want to do that??

                  Rick, there used to be kits out there to do that, but I have not see one in years. Air is a great "spring" because it is progressive in its' compression, meaning the more you compress it the harder it becomes to compress which is what you want. The kit (if you can find one) is the way to go. Most have an air tube that balances the air in both fork tubes.
