Suntour shocks currently seem to have everything from very basic binnables to good but heavy shocks. I too would recommend RJ the Bike guy for strip down and rebuild information, if I were to do so. In a lot of cases, I just replace with a rigid fork, and take a couple of pounds off the bicycle. I do the same with Rock Shox Jetts, though, except I usually move up in the line and keep the suspension on those. Some shock rebuilds require some quite unique tools, I might add.
