2016 RMZ 450 air forks, help!!

They need revalved, find a good suspension person. They will be way better.

Best setting I found for those forks was to run no air, yip a spring conversion makes them amazing!

If they're harsh try going up in psi in the balance chamber by 10-20 psi so like 180/0/190

185 in the lower chamber
160 in the upper. Leave the outer chamber at 0.

More air in the bottom chamber= a more plush feel.

Racetech GoldValves 177/0/194 with the glide kit and it feels really really good and I’m 195-200lbs

I tried a 1000 settings and never liked any of them. Id say look for a set of spring forks. U can sell them when u sell the bike seperately get your money back.

Been googling for a while, apparently one good thing to do is mix engine oil with the fork oil in the air chambers as it is a better lubricant. I have noticed myself that fork oils and ATF don't stick to the sides of the funnel unlike a motor oil. I will give this a try, seeing as there is no valving this side it can't hurt!

Also, looking up the recommended fork oil (Shows ss19) it is 14.4cst @ 40c, which is closer to most brands 2.5w as opposed to their 5w. So I have some silkolene 2.5w (15cst @ 40c) to go in. Most brands tend to hang around the 18-22cst mark for 5w, so I'm hoping when these were last serviced some thicker oil went in!

To do list -
Install glide kit
Use 50/50 engine oil/fork oil in air fork
Remove base / mid / rebound valves and note shim stacks
Rebuild damping leg with glide kit also
Use 15cst oil (silkolene rsf 2.5)
Set pressures 180/0/190
Hope.

Righty, everything is fitted! But being new year's etc, I've not been a me to try it.

Apparently the clamp shim on this is 24mm but I found 26.15 and 26.30 on too of eachother. Anyway, I took 2 face shine from the rebound stack away and put a crossover in after 3 face shims. With the base valve I moved the 26.15 from just before the clamp to just after the 3rd 36.20. I'm hoping the rebound will generally keep the bike a bit higher in the stroke, as I was maxed out on the clicks and it still felt too slow. And the compression I'm hoping alongside the glide kit will just take the bite off of the smaller movements, I loved the way this bike absorbs big hits so much I actually ride towards the biggest bumps I can, but the smaller stuff there was always a bit of deflection. I'm hoping these minimal changes alongside the glide kit maintain the general feel of these forks, but with a tad more comfort. Have to wait until Sunday to find out though :'(

Bike was a hell of a lot better today :D! Got the compression at 10 clicks and rebound at 16 so could possibly still lose some more rebound. But breaking bumps are gone! And even the smallest bumps like the step putting the bike in the van are absorbed nicely. Very happy :D

Could you help me out please, and check the triple clamps clamping diameter on your bike?

Top 55
Bottom 59.2

Yeah that small bump compliance can be contributed to the glide kit. It really is the single best upgrade you can make to a TAC setup

That and easing off the rebound more. I took 2 face shims out and added a crossover on the rebound and am still nearly all the way out on the clickers. It surprised me to be fair, I'd never felt it as obvious as today where you could feel the front wheel not following the ground between successive bumps, as I eased off the rebound it got smoother and smoother. I'm really starting to love this bike now! I can't imagine how people buy new bikes year after year when it takes so long to get one sorted how you like it anyway !!
