Title: Shock Valves/piston
Post by: He Man on March 27, 2010, 05:14:06 PM
I dont know how shocks work, but i palnned on taking it apart and sending it to get recharged and some new oil. Ive heard of people dirlling the holes for the valves to be a bit larger and was wondering if the same can be done for shocks. AFAIK they dont have valves for 999 showas. Just trying to get a bit more performance out of them

Rather than assuming that more is always better...

ask a suspension guy what you need to do.

You can drill the holes larger to reduce high speed damping, but you still need the shims to get proper low speed damping.  Race Tech does make valve kits for the Showas, but, like Nate said,

In other words, call ECS.  You also need a tank of nitrogen and a regulator to recharge the shock.  On second thought, send the shock to ECS.

I was going to send it to them to service it, but i wanted to drill the holes myself since im pretty sure they wouldnt approve of it (its bad enough i bring them my bike in the condition it is, i just feel bad lol)  But if there are valves then yay!

Ill check the price. After buying it and installing it though, if its cheaper to just buy an aftermarket ohlins pull of from an S4Rs or something, i might just do that instead.

Have you ever seen a shock/fork valve?

The holes are rarely round.

Do you have a square drill?

You'd still need to get the Ohlins set up for you.  I'll take almost anything apart, but I wouldn't screw with a shock.

Good advice!   [thumbsup]

If you can afford it just send it in to race tech or something.  Nothing wrong w/ that.

The difficult part is not screwing with the shock or fork, it is getting it right for you.  When you hand the job over to people like ECS or ducvet the most important ingredient you get is years of suspension tuning expertise, both on our bumpy NE roads and track.

thanks for the advice guys.

THe racetech valve is ~$160 bucks. When i get it pulled of to get serviced ill ask them to throw it in for me, unless they think its not worth it.
