Guys,
Last week I ordered a bunch of fitting, and fork oils to design a set of air valves for the Grom front forks, and improve the fluids response to the forks movement. First I blended a couple of fork fluids together to make a slightly heavier fork fluid, to improve the dampening. Next I designed and machined 2 air valve assemblies for the re-machined top fork nuts. I removed my machined spacers from the forks, when I installed the air valves, so the forks are at stock length. I added my new fork oil, and tried various air pressure, 18 psi being the best for my weight. What a difference in the way the bike responds & feels in a corner. It's like night & day. I am not an advocate of tearing the complete forks apart to replace the springs, since sliding tubes were not designed to be disassembled by Showa. It's way easier to just remove the forks, drain the oil, and add parts to the top end that fix the problem. I ordered a second set of Honda fork top nuts to time myself, so that I can see how much it will cost to convert the system to air assist. Please look over the pictures,
Brian
