Terry may well be very good, but personally I reckon those gold valves are a crock of shit!! From what my suspension guy in Melbourne tells me, a lot of the modern suspension has very very very good quality internals, and all they need is a respring and revalve usually to make em work properly. Every top racer I have spoken to about gold valves reckons the same!!!! FWIW I would be more inclined to have it done properly than fitting gold valves!davezx9r wrote:i'll give these guys a plug, terry knows his stuff.. he did a gold valve job on my old blue zx9 (which ended up going to I-K a few years back), and recently he did a gold valve job on the gixxer's forks and set up the suspension to match the new ohlins rear shock that i got as well... and the bike's like a razor now, even more so than when new.. so yeah, the guys at shock treatment do a good job.
the missus liked what they did to my gixxer so much she's planning on taking her gixxer thou K6 to shock treatment sometime to overhaul her suspension.

I presume from your comment that you mean the holes are larger in diameter, this is correct, however the compression and rebound dampening except on small bumps is controlled by the shim stack.hoffy wrote:gold valves are bigger diametre, all this means is they allow faster compression & rebound than the stock smaller valves, which is great on the road for reading different and inconsistent road surfaces but indifferent on the track where its nice and smooth.
They do work on road ! but are indifferent on the track as they are not needed due to the consistent & smooth road surface.
Well, Terry Hay told me that setting a current litrebike or the 12 up for the track you would not need gold valves, as the standard valves allow enough flow. Gold Valves are designed for road use, specifically sport tourng comfort on less than race track smooth roads.Neilp wrote:I presume from your comment that you mean the holes are larger in diameter, this is correct, however the compression and rebound dampening except on small bumps is controlled by the shim stack.hoffy wrote:gold valves are bigger diametre, all this means is they allow faster compression & rebound than the stock smaller valves, which is great on the road for reading different and inconsistent road surfaces but indifferent on the track where its nice and smooth.

The original valves made by Race Tech were made for the track hence the name, as original equipment valving was not good enough for the track.
The valving etc is even more important on the track as it gives racers that edge. It had nothing to do with the smooth surfaces found on race tracks but has everything to do with keeping the rubber on the track, improving things like corner speed, braking etc etc.
Remember Yamahas problems last year with front end chatter? Suspension was most probably part of the problem. Even Doohan complained about front end chatter on the NSR 500.

Gold Valves were originaly designed for the track as I explained in my previous post. It is not the valve that controls the oil flow on large bumps, but the shim stack. For small bumps the oil is forced through a number of small orifices near the centre of the valve. The number and size of these orifices varies between manufacturers. Your bike can be made to handle better by careful selection of valve type and shim stack configuration, however how this is achieved is open to interpretation. That is why suspension is still considered by some to be a black art.hoffy wrote:Well, Terry Hay told me that setting a current litrebike or the 12 up for the track you would not need gold valves, as the standard valves allow enough flow.

Unless there are different types of gold valves?
And yes the valve is generally the part of the unit that the oil flows through.
