So I want to improve the suspension on my stock 350x but not wanting to break the bank. The front has been rebuilt with new slider bushings, oil and seals. The rear seems ok but it doesn’t feel like the compression adjuster makes any changes as I turn the knob. All the way soft and all the way hard feels the same when I push down on the rear end. For race tech to rebuild the stock rear shock is $330. I’ve heard good things about the the gold valve upgrade but that was $550. Front fork emulators are $179 plus $50 to modify the springs. I have a second rear shock but don’t know the condition. It looks ok but no gas escapes when I push the Schrader valve so I’m guessing it’s empty. Is that where the nitrogen gets filled? The threaded part that goes around the valve that the cap screws down on is also missing. It’s just the actual valve sticking out of the reservoir. The shock on the bike now let’s gas out when I tested it. Also the bushings on the spare shock are shot. So looking for advice on what’s going to be the best bang for my buck. Front fork emulators on freshly rebuilt suspension or do the rear which the condition isn’t really known? And which shock do I send? The one on the bike now or the spare in worse condition? I don’t want to lose a lot of riding time. I also have a spare set of fork springs I can send to get modified so no down time for that. I ride mostly on tracks because there’s no land where I live. I like jumps and going fast. Your expert advice is appreciated!
