I have '93' GS500 that on which I am currently replacing the chain. I bought the bike last year with only 3700 miles on it so it had a lot of garage time in it's past. I have discovered several stuck parts including the chain that stays kinked when you bend it. (I took a chance riding it all last year on such a lousey chain but I couldn't stand to see my buddies ride by while I waited for parts.)

When I removed the swingarm I noticed that the rear shock, now suspended by the top mount only, was rigid in its mount. This is my first GS but it seems to me that the top mount should pivot freely for and aft. When I completely removed the shock I discovered that the bushing in the top mount does not rotate at all.

Here's my question: Should the rear shock, top mount bushing be rigid or should it rotate freely? :dunno:  My Clymer manual doesn't give any information on this detail. I would hate to use force trying to free up the bushing only to discover that its supposed to be fixed. If it is supposed to rotate I doubt freeing it with pliars and WD40 will do any good anyway. Once the rollers are that corroded the only fix is to replace it.

Which brings me to question #2: I usually use OEM parts but if anybody has had a particularly good experience with an aftermarket shock please let me know what brand and model. Thanks :)

Top shock bushing doesn't rotate... That when bolted in will not even move if you yanked it front to back... However when the bike is moving the linkage will be able to move it if needed... very very very little is all it will need to be moved. Aftermarket shocks are OK... some racers here have tried Fox or other shocks... but the Katana, RF, B12 shocks work best for street GSes. Especially if you weigh over 160-170 lbs in full riding gear get one of those. If you are heavier/taller/and more agressive or hope to do a bit of track with the bike... get a GSXR 89-95 750 one... A little much for the street but will work on the track.
Cool.

seshadri_srinath: Thanks for the quick reply. I won't be needing a new shock since this one appears to be up to standards, but thanks anyway for the aftermarket information. I will squirrel it away for future reference.

Back to the shock. If the upper bushing is stationary, how do you install the shock to insure that it is correctly aligned. Do you tighten the upper bolt after all the other parts are in place?

While we are on the subject of shocks, how can you tell which shock setting you are set on? I couldn't find a pointer or any kind of indicator for reference.
