View Full Version : Racetech Gold valve shock conversion?

Hey all
Has anyone done this conversion? I have a gsxr600 k7 in stock form and am looking at buying this kit for track use (superstock). I've stripped my rear shock for a perv and can see that the gold valve piston is really... REALLY open compaired to the std one. It looks like its also the go to get the Race Tech Shock Rebound Separator Valve. So cool! just wanted to know if anyone has tried this stuff or is there any other branded easy conversions like this out there thats been tried with good results? I also thought about machining out my std piston, they look pretty simple in design, so i guess if i do it on a cnc mill i can get it pretty accurate, but how much to take out, is it a case of more the merrier, because as i said the gold valve piston is very open.
maybe its just easier to buy a kit? :laugh:

I'm not sure I would be doing anything before the regs are confirmed for the Superstock class bro!

Well either open or not for rear shock... this is very many much cheaper for me than going for a complete aftermarket shock, so my questions still stands.
thanks for the concern though, very nice! ;)

Biggles is right, dont do anything until the new regs are set in stone.
As for being cheaper maybe initially but have you factored in respringing, have you factored in that you will need a spring rate specific for Teretonga and then perhaps another spring rate for Hampton Downs if you go to that circuit? Have you also factored in that oem shocks need servicing a lot more often as the oil and performance goes off a lot faster. There is no internal top out spring for more stability under brakes, the shock is too short and requires spacers under the top mount etc etc.
At the moment very convenient spring exchanges apply for the most predominant aftermarket shocks out there, this will not apply for modified oem shocks as the springs are all different and even aftermarket springs most often require sizing adaptors ( more cost ) I dont see anyone stepping up and replicating in oem springs the 30 odd k of rotational springs that I currently carry for TTX and cartridges. Leading aftermarket shocks also have great residual value, even further enhanced by the ability to respec to suit a different bike given their modular construction.
Indeed a Race Tech piston kit and flow rebound seperator does improve a oem shock markedly, aftermarket shocks already have had these flow seperators for many years and Race Tech say they invented it!!! We fit lots of these and did two sets today but it doesnt stop there, there is lots of other stuff that can be done internally and we will be doing that if that crazy rule proposal goes through.
We have all 5 600cc class shocks apart at present plus an aftermarket Showa racing shock for a CBR600 that you can oreder through a Honda dealer. The message there being that they deem it neccessary to have a proper racing shock if you want to go racing, with all the convenience features.
Add to that it will take a season or two to get on top of settings that work at all circuits and dont believe the BS rhetoric coming from other quarters. There will be issues, there will be lots of initial tyre expenditure and there will be more crashing. That equates to more frustration and more cost.
I have thought about this long and hard with an open mind but keep coming back to the same conclusion, high quality aftermarket shocks are sold worldwide in large quantities because the stock shocks are just not up to the job, even in highly modified form there will be horrible compromises. That is not a commercial statement, a lot of people have come to the same conclusion.
At present we can revalve a TTX in as little as 10 minutes, stock shocks 30 to 45 minutes. That makes life not so easy for the suspension guys or anybody else
Its not the ''low cost'' bed of roses that many think as the negative by-products are there in abundance.

Great info thanks. I see what you are saying. We love the Flash aftermarket shocks, but I am after a kit for when we can’t run the flash shocks as that’s what is going to happen. AU rules. ;)
As for being cheaper maybe initially but have you factored in respringing, have you factored in that you will need a spring rate specific for Teretonga and then perhaps another spring rate for Hampton Downs if you go to that circuit? Yeah so I was thinking about building two shocks, 1 calculated for teretonga and one for the others. It still works out half the price of a aftermarket shock using the gold valve kits from the states. I have also had a 10.5 spring made that fits the std shock. Which was quite cheap so I guess I could make another.
Have you also factored in that oem shocks need servicing a lot more often as the oil and performance goes off a lot faster. There is no internal top out spring for more stability under brakes.
As I said I am looking for other ideas not aftermarket so this is ermmm no applicable to me right now. If they allow aftermarket shocks then GREAT I got one sitting here now I could use.
the shock is too short and requires spacers under the top mount etc etc. apparently so… I splashed out $5 for some spacers that range from 2mm up to 8mm.
Indeed a Race Tech piston kit and flow rebound seperator does improve a oem shock markedly, aftermarket shocks already have had these flow seperators for many years and Race Tech say they invented it!!! We fit lots of these and did two sets today but it doesnt stop there, there is lots of other stuff that can be done internally and we will be doing that if that crazy rule proposal goes through.
It’s a shit rule, I am being prepared.

The silly thing is we will probably make more income out of this if it goes through. But its going to be pretty miserable for a lot of people when they realise;
1) They just cant access a foc exchange spring anymore, especially when they might really need it because they are burning up expensive tyres
2) They cant just roll into pitlane in the middle of a brief practice session and have the spring preload changed within ten seconds and then out again to check the result before the session finishes
3) They cant adjust the ride height anymore within 2 minutes, especially so with the CBR600
4) They cant get a revalve done inside 15 mins anymore
People will be buying spare oem shocks to keep themselves ''covered'' Where is the flipping saving in that?
Etc etc

Why use a CNC? My mate just used a hand file, cordless drill and vice grips (and a pipe wrench if it is difficult to hold some bits) and he said it makes a massive improvement. PM me and I will give you the instructions. :msn-wink:

Actually u can pick OEM shock up for very little on ebay from the US. as in 45 with 35us delivery, but i get what ya saying, in an ideal world we just bang in a top notch product that can be easily modified. i can save money by doing this work myself but it will be hard for the user who has to pay whoever to do everything. so yes you will end up with more work if this ruling does go thru. YAY for stupid rules! actually its as stupid as running the OEM chain pitch.

I don't think it matters, whatever you can find. Even some 60 grit sandpaper would suffice, finish with 120 grade.

At least with CNC you will have consistency for every piston. That means valving specs can be consistent between shocks and I think its perfectly reasonable to expect a minimum quality that will attain total consistency.
Surely you are not using vice grips on suspension parts?????!!!!

If you look closely at high quality aftermarket pistons ( Ohlins, Race Tech, WP and Penske ) its more than about just the port size. Theres quite a lot of detail in the lead in passages, surface finishes to minimise shim hydrostatic suction, a correct amount of piston ring drag but also having expansion on that ring to compensate for the crazy expansion that occurs with the alloy bodies.
And dont get me started on nitogen bladders and how oil areation occurs all too quickly turning the oil into a semi compressible milkshake. Its for very good reason that the very best shock manufacturers exclusively use dividing gas pistons in a micro-finished bore.
No one has mentioned here that often the rebound needle tapers in oem shocks need reprofiling, we did one today to achieve an appropriate response range. Most of these shocks are full of unpleasant little fish hooks.
Self instal marketed kits are fine but thetre are a lot of real world detail issues not mentioned in the fine print.
In high quality aftermarket all of those issues are already taken care of.

I bought the goldvalve kit and it arrived in 3 days, yes THREE days from the states, purdy quick and too cheap really! I went for version 2 as racetech talked me in to it lol, no idea what the difference is but they said if i have the time and can farrrk around with them then they are a much better option..... ermmm sure thing!
I also got some heavier fork springs, cool! i well under way for my superstock ermmm... conversion?
Hoping to have the front end sorted for testing next week, ok ok maybe the week after.
Next up i need to remove the exhaust valve thingy and find a better muffler (anyone got a fucked one for a 600 that needs a reskin?), make a new middle pipe (to the same size as the length removed) ;) ermmmm what else?
i dont remember seeing anything in the rules about dialing ya cams in, slotting ya cam sprockets? is that shit legal?

It would have arrived the very next day if you had purchased locally and supported NZ business. And the price difference wouldnt have been what you think.
Is the company in the States you bought it off doing a whip round for Christchurch earthquake relief? I thought not, many NZ businesses will be helping.

Ive just installed a couple of the very latest pistons myself. The sad thing with this new Superstock regime is that hpose who called the shots on the new rules really have no idea of just how many bad engineering issues there are with stock shocks, almost everywhere you look. When you work with a high quality product those issues become a hell of a lot more apparent when you work on the stock stuff.
Thats not trying to bag stock stuff per se, its just not the land of milk and honey that some would have you believe. And in real terms the cost savings are not what people think.
My thoughts on buying offshore are well documented in previoius posts and I make no apology for those opinions but I thought that in my own cynical way I made a relevant point. I can understand some of the reasons why people buy offshore and am certain ( and indeed invite ) that I could have a decent conversation with you about it.
The reality is that given the overall worldwide market those of us in local markets at the forefront of selling products such as Race Tech are in fact flexible to the market realities, if given the opportunity. Look in the very near future for some price realignments with such product, on top of existing local technical backup if you buy locally.

I have always believed that flow is what it is all about, that is why there are shims in there mate, the only trick to it, is determining what is going on with your bike when riding. is it squatting, re bounding to fast etc, and then knowing the area in the shim stack to alter to achieve your goal. This was some thing that RT and I achieved together when there were NO Ohlin;s unit for the GSXR range, together we built the units for the 600/750/and the 1000, Ohlin;s europe were very impressed with our work, well, Anders Anderson was any way, according to the emails to RT I saw about it.
It may take some time, but that is what it takes. Also improves your riding skills hugely, if you do not test/try different, you do not know what could have been achioeved
RT/CKT have all Ohlin;s data on hand, as well as all the history of the riders here using there product, so can normally alter an Ohlin's shock to work very well here, but unfortunately do not have a working Dyno any longer, to start buiilding OEM shocks based on the characturistics of an Ohlin's unit, so this new rule is going to be a very good challenge for them, which I am sure they will do well with.
I have sent a race shock I like oiff shore, as well as a OEM shock to a mate with a dyno, and are having him build a nOEM unit based around the Dyno graph of the race shock action I like for the GSXR 600/750 bikes.
We will run this shock in the SS or Prod 600 class, the class we enter for the NZ Champs, is totally the riders call, as per which shock to use.

In fact CKTs suspension dyno will be up and running in a handful of weeks as we have a replacement part underway that was causing an intermittent problem.
Suspension dynos are a very good indicator of a reasonable starting point and show the effect of changes. Not foolproof but better than flying blind. Certainly have learnt a LOT from it.
With the Ohlins TTX and cartridge range all the work is done because they supply the graphs for all the setting combinations which we use as a reference trackside. We have a few variations on the theme but dont stray a mile off course as it were. Have also learnt a LOT from this system. There is never a perfect setting and there isnt a shock that exists where you can do everything externally with clickers, anyone that says otherwise is also fooling themselves.
With the TTX40 auto based shock its taken a step further with a Valving Reference Programme. You input your new settings and can overlay the resultant graph that it spits out over your existing setting. Very trick and over a million combinations. Weve used these shocks with both Craig and Glen Skatchill. Currently one is fitted to Ozzys F3 bike and Chris understands its response range and character better than I do because he has worked with it for so long.

With the Ohlins TTX and cartridge range all the work is done because they supply the graphs for all the setting combinations which we use as a reference trackside. We have a few variations on the theme but dont stray a mile off course as it were. Have also learnt a LOT from this system. There is never a perfect setting and there isnt a shock that exists where you can do everything externally with clickers, anyone that says otherwise is also fooling themselves.
With the TTX40 auto based shock its taken a step further with a Valving Reference Programme. You input your new settings and can overlay the resultant graph that it spits out over your existing setting. Very trick and over a million combinations. Weve used these shocks with both Craig and Glen Skatchill. Currently one is fitted to Ozzys F3 bike and Chris understands its response range and character better than I do because he has worked with it for so long.
Hey Robert
You will be pleased. I have taken the bike and new fork internals down to your South Island, Christchurch Ohlins Person for installing and setup.
Brendan... Supporting the local guy! :msn-wink:
