I'm in the process of rebuilding the rear shock on my 98 kDX 200. I don't think the fluid had been changed since the bike was new :scream: !! I'm going to the 5.2 spring since I weigh 200 pounds so I'm sure the suspension will respond much better once it's rebuilt.. I was thinking of putting aftermarket valves in to further my suspension bliss. Are these gold valves worth it or not? Also, does anyone have any experience with the "Delta Valve"? It apparently replaces the stock compresion adjuster. Does this fit on the kdx shock and if so, is it worth the money? Thanks for any advice you can give!!
