did service my SID race & team from arround 2005 last year and it was not a big deal to service them anyhow. Only you have to make yourself some special tool to remove the the damper unit from the stanchions, but you dont need to remove the airdamper if still fine and holding air. the pure delite unit is removeable without any special tools.
very helpfull, I found a manual which you can download from the internet. bushing removing also involves special tools - the internet is also you friend as both the bushings and the tool are still available.
changing the oil in the pure delite damper and giving the interior a good clean should help returning your fork to full travel. the main weakness of the SIDs are the stanchions seals, which when not regulary changend, helped to let water ran in between the stanchions and the casing, causing the stanchions to corrode and in the end the fork did not compress any longer, due to corrosion.
hope yours is OK, so its vital to change to seals regulary !
