well im thinking about getting the suspension on my CR250 revalved because its really beating me up right now. precision concepts is pretty close to where i live so i would like to know if thier suspension is good or not. i would like to get it revalved for mx. so is that a good place to go for a mx revalve or should i look somewhere else?

MX-Tech is also giving a 10% discount on revalves until Christmas or the New Year (check their website).

per end
why is there such a difference in companies? some are in the 150 range and then there are others (usually more well known companies) in the 225-275 range i know the labor is usually pretty close. is it the parts? and if so why such a difference in pricing of base valves, seals, etc.? i know fluids are all pretty much par for the course. i know shock doc, marcus, and probably jeremy will have some good replies for us. alright guys the finger is pointed lets hear it? ;)

At times, the difference may just be the additional piston kit that the suspension company installs. $150 will most likely be for changing the valving stack for use with the existing piston assembly. Some companies feel that their piston designs improve upon stock designs, and can make for a better overall package. I ended up spending the additional sum for a complete re-vamp on my last two bikes, and was happy with the results.

Yep main difference is if you have a aftermarket piston set up-these are not cheap.
Typically you get what you pay for, and I think it is No differece here.
We have a pretty good reputation at the track and have let several riders check out our bike. All of them thought there was something beneficial to the MX-Tech (Jer) suspension. I'm thinking Jer will be gaining some business from the riders in our area.

IBWFO i'm not questioning your company's talent and abilities(i know Jer and the guys have a great reputation :thumb: ) i would just be curious to take two talented suspension specialists and have them revalve two bikes(same brand/model/yr.), for one customer,but one w/ an aftermarket valve setup and the other w/oem valves both set specifically for above said rider. I'm just curious as to how much of a difference it would make between the two. I am quite certain there's a difference i would just be curious to see if it's enough of a difference to make us limited budget riders willing to shell out the sometimes twice as much price tag.
If you are on a limited budget then you have three options for a low cost revalve.
1. Install RT Gold Valves yourself and get the benefit of an aftermarket valve w/ custom valve stacks. This is a good option for people that know what tools are. Also, you can tweak the stacks until you are happy with the performance.
2. Experiment with revalving the shim stacks yourself. This takes a lot of trial and error. It also requires a certain amount of expertise with tools and forks.
3. Send your stuff off to someone that revalves the stock base valves. The downside of this is that if you need to tweak the valving you have to pack the stuff up and ship it off for a week.

Hey Cam,.......
flynbryan:
We have been Race-Tech fans for years,............UNTIL...............we got the KTM. I spoke with a guy from WP and got the specs on the WP shock and compared it with the Race-Tech specs..............VERY, VERY different, almost scary.
I know there are some great susp companies out there and Jer will tell you that, but we are getting a little more serious about racing and felt Jer was the way to go. Everyone needs to do their own research and pick what's best for you. You asked and I gave my opinion.

I know nothing about Precision Concepts, however, when people spend $50,000 on a motorhome, $12,000 for a couple bikes, $2000 (or more) on gear, etc, etc, then only consider the $100 saved on suspension company xyz with little consideration to training, education, product support and performance......................then go out and do the 100ft double..........makes a person wonder!!! :confused:

I believe suspension will improve a riders lap times more than any other mods.I have used low flow pistons and got good suspension action.I have used std pistons and got good suspension action-not sure if it matches the low flows as yet.I have never tried large port pistons but would do if they were made available to me, as i belive in trying everything before deciding.However i wont spend my own money on large port pistons, as i dont at present feel the bigger is better theory applies to ports.
Yep, WP shocks are their own unique animal and should be only be serviced and modified by someone with the proper equipment and knowledge.
RaceTech Gold Valves do work well in WP forks. They are now producing a new Gold Valve shock piston but I haven't spoken to anyone that has installed one yet.

Its a bit worrying when the mags test Crockards works bike and declare the suspension unrideable-it was super harsh and yet blew through the stroke on nard hits and bottomed badly .I rode a 02 KTM 125sx set up by Langstons Wp tech to the same specs as langston-horrible-forks soft and mushy, shock stiff and sat up high in the stoke causing headshake.A std 02 Cr125 was far better.All i can say i would look to someone who does change the wp stuff, as the std stuff is a Pile of Dog Sh*t(PDS)

I have had good and bad results with MX-Tech. 00 01 YZ 250's were great, an 01 CR 250 a big improvement over stock, but the front end chatters quite a bit. And an 02 YZ250 thats been back 3 times and has gotten worse each time. If I dont sell the 02 this month I am going to send it to RG3 to see if maybe they can sort it.

hi big al, i am in SD also and have looked into all of the local suspension shops in great detail. Madracing in Vista is my choice. I met with the guy at carlsbad track and he helped me out even before i had given him my business! He is at all of the local tracks and will revalve both ends for arounnd $300 total (not including springs if required). he was a nice guy, and is willing to re-do them for free if you dont like them and will also come and watch you at the track for the final dial in. i will go with him for my revalve this christmas, i have heard nothing but good things locally. that fact he still rides means something to me also.
i have heard precision concepts are also good but have no personal experience.
the other option is mx-tech franchise at lake elsinore, so figure into the extra cost of the round trip etc., i do beleive the guy there will come to the track also if you want and re-do it if you dont like the set up. the extra cost is for the differnet pistons, personally i dont think i need to spend the extra cash to get my set up as i want it.
the other option is RG3, again a very good rep but it will cost around $400 or more and then you have to drive to anehiem.
i also looked into sending it, but that gets expensive, at least $30-50 each way, and if you want it re-done then its gonna get real ugly that way!
drop me a line if you want to hook up and ride at some point

I know two guys who use Precision concepts suspension. Both are extremely pleased by Bob Bell's work. Being very close it would be easy to go back to him if you needed some fine tuning. He is well know mostly in the off-road sector.
As far as price goes, In '97 I paid Pro-Circus good money to make my YZ suspension worse than stock. So I guess it could hold true that the more you spend the more they can ruin it too.

thanks for all the replies, it says on their web site that they do the suspention work on Johnny Campbell, Steve Hengeveld, Jonah Street and Tim Staab's bike so it seems like they know what they are doing. i went to the track on thursday and yah, my suspension really needs some help so i'll probably be going to them soon. thanks again for all the help.
