          my 89 1100 sags

          The horn is hitting the fender on some bumps and appears to sit really low when I am not on it. Will new 15 oil bring it up a bit until I can get these progressive springs everyone talks of?.

            longer spacers in forks

            has anyone done this with PVC piping? I here this could work to stiffen things up and alleviate some sag.

                The spacers i took out are 7 7/8" (200 mm). I was planning to make PVC spacers at 9 1/16" (230 mm), adding 20 mm preload. My Kat is really sagging, on bumps the horn hits the fender, plus I weigh 240 lbs.

                At 9" what was the ride height like?
                Why did you take them out?

                  I was 240 when I did mine, trust me 9" is enough. It is hard to compress them at that length to

                    Put in a 20 mm spacer and 15w oil and rides nice and is stiff.

                        All I did was cut a gray piece of PVC electrical conduit from home depot, its almost the exact diameter ,also a flat metal washer machined to the diameter of the washer that is in the fork to make up the 20 mm, therefore 17mm pvc, 3 mm thick washer. The washer is on top of the spring and spacer on top of the washer. Hope this helps

                          Still bottoms out from time to time

                          Going to try the progressive springs, their on route from MOJOE.

                            progressive springs , the way to go

                            Its done, much stiffer and better ride. Used a 4 1/2 spacer with the springs. It also raised it about 3/4 of inch. This is the better solution.

                            Although the 3/4 spacers on top of the stock setup worked not to bad with occasional bottoming out.

                            Anyone want these 3/4" spacers, i'll send them by mail. please PM me.
