GSX-R 750 Pictures of how I set the front fork oil level on my 1985 1986 1987 Suzuki GSX-R750 motorcycle.


But first, lets pay some bills:

  1. Took off plastics - pics of that in "Fairings" in menu on left.


  2. Lifted the GSXR. Put blocks of wood under this side.

  3. Lifted the other side with a bottle jack. This got the front wheel off the ground.

  4. Pulled the black rubber caps off of the fork plugs.

  5. Removed fork plugs. Here are the fork seat, spring guide, and plug with o-ring and adjustable preload. No spacer for the progressive springs. There's the big socket to remove them, and some ATF to top off the forks.

  6. Here are the fork plugs, showing the o-ring and adjustable preload.

  7. The preload adjusts using a big screwdriver to push down the inner cylinder and turn it so it catches at one of four different heights.

  8. The spring heights were not exactly equal, so I shimmed one with a washer. The washers I use to adjust the camber on the pathfinder are an exact fit.

  9. I put in a couple ounces of Automatic Transmission Fluid to try to stiffen up the bars. I overfilled at first, then measured the syringe and tube and sucked out as much oil as it would reach at the measured depth. I removed one inch at a time, and tested each setting for firmness till I found what I liked. I experimented a lot and ended up with the oil level set 9" down from the top of the tube. Note that these are not the stock springs. I do not know if they are progressive or just bigger, stiffer springs from a Jeep grand cherokee like the ones in my Pathfinder.

  10. Fork seat, spring guide, (and washer/spacer) and plug back on fork. I set the cap to the lightest preload to get it on, because it is a mother to get the thread started. "Don't ever get old," as my Grandpa used to say. Then I tested and adjusted preload.

  11. Rubber cap back on.

  12. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!


  13. Then I finished my beer.
