Brandon, I agree with the others about Peter Caldwell at Worldwide, really first class work. Peter gave a seminar on shocks at the Spridget 50 meet and I learned a lot. First you could try draining and refilling your shocks. Getting the air bled out after refilling is a bit of a job but you should be able to get all of it worked out on the bench. Peter said to use only a 20 weight hydraulic oil, nothing heavier. Heavier weight oils only cause damage and really don't do much to improve the shock action. The real change is with the vavles and those are easy to change and not expensive. If the shocks still don't feel right then it may be time to get Peter to rebuild them. What you'll get for your money will be a shock with actual bushings installed in the housing instead of metal to metal contact, a new seal surface on the shaft, and a proper lip type seal instead of the original wick type packing. Add a full guarantee and you can't go wrong.
By the way, after seeing how these things were put together you can see that there's no way to rebuild one at home. It takes a special puller to remove the arm and shaft from the internal rocker arm under rather high tension and a special hydraulic press to reinstall, then the rocker arm has to be peened to the shaft. Even then you wouldn't have any way to refurbish any of the bearing surfaces or seal. Let the pros take care of any rebuilding.
