I want to redo my suspension on my 02 XR650R...looking for some recommandations.
Precision Concepts in Temecula California. They do Johnny Campbell's.
Check this out; http://borynack.com/XR650R/
PC is one of many that can do your suspension, PC is very over priced though.
Precision concepts will not sell you the same suspension they put in Johnny Campbell's or the American Team Honda Baja bikes. All if that is their "top secret" proprietary stuff that they won't share. The stuff that you get from them is pretty much similar to all the other suspension places out there that do the 650R's, you just pay more for the name of the shop doing it.
ESP does a good job. There are others also. I'm not sure if Barnums still does suspension. I'm sure more people will speak up with other suggestions.
Go to the site that the DEZ is talking about,it's got the stuff if you are capable.
RPS Motorsports in Placerville, Ca. Cliff does a good job on these bikes...
PhilM, that's one damn scary avatar, hope that ain't really you.
Suspension by Jake in Riverside, CA. 951-681-2829 very good with the 650 and fair priced. Most of the guys mentioned are desert folk, you probably should find some one the sets em up for CO.
Barnum does great work. He did my friends and mine about 2 months ago and we are loving it.
Guy is a D37 champion and has raced many score races on a 650R. He does the work himself and is very helpful.
barnums pro!!! rob did mine and it's great alot cheaper than PC
Yah Barnum's quoted me at $660 total for the whole shebang.

That's what I paid PC a few years ago to do mine. I called recently do do another bike's suspension and desmog(easy) and they wanted 1500 bux. See what fame will do for you.

Maybe it's not the same as what Johnny and crew but PC's work is amazing! I had them do my 650R and I was more than pleased with the results. I also just rode the 450X we will use for the 250 and 500 and was more than amazed at how well PC can make the 450X too!
george at esp .does good work great price too.
I am not here to bad mouth PC, Barnum, Baja Designs, RaceTech......
I have taken apart many XR650R, XR600R, XR400R, CRF450R, CR250R, CR500R and other bikes from each of these suspension builders and there is difference in what they turn out. I have pictures and very careful notes of what each use and do to get close to the same results. Talking of just the XR650R, there are some that use just the shims to acheave their goal and 5wt fluid. I have taken there shim stacks apart and found hair and grit between the shims. Very bad workmenship and still they are thought as doing wounderful magic. The shock rod is just ground flat with a bench grinder. No torque wrench used. I have been in these shops and this one that is hailed as awesome does not take the work near as serious as the others. These riders could speak up (and have) on this and other groups but, not without trouble. There was one on this group that had his shock come apart because of faulty work and broke his neck. He had angles that kept him here. Gold Valve or porting the valve for the forks are very close and need little change in the shim stack to get the same outcome. PC uses a very cool bottoming cone that most do not use and they use a very light fluid. They do good work and I have had a lot of there stuff here. It has changed over the years to keep up with the learning curve of true racing. Still way to much money!!! Racetech Gold valve/shim packages have some thick shims and not the best for a plush ride for the XR's use, great for MX but, not desert racing and trail use. Baja Designs and others are just installing Racetech's Gold valve/shim setup. Thicker shims means you can use less shim but, they bend slower. There are many, many things at work in the suspension to have just one change make all the difference. PC does a very good job one the high end $1500 setups of having all systems of the suspension do there job and comploment each other system at doing theirs as does the suspension setups on the www.borynack.com/XR650R pages give a very plush ride and resists bottoming very well. There has been a lot of work put into a better responce during multiple hits during 'G' outs. If you can follow instructions well, read all the links, make tools, and have good machanic skills you can do as good or better job the most suspension shops out there, with these pages. I have been screemed at by one shop for giving out shim stacks but, like I told him not everyone is willing to try to do the work thereself. If they would let others have the facts, to have a working finished product it would help get the word out for those that want a killer suspension also but, don't want to do the work, turning to them they get more biusness in the end.. I get tons of pm's, emails and phone calls and have done my best to answer all of them as fast as I can. It is not about money for me, I like seeing riders get the most out of their machine and that means the pride of biulding it theirselves. There has been over twentyfive XR650R suspensions done for riders here and on the Yahoo XR650R site for free labour to test of all kinds for different riders and styles. Many bikes have race SCORE, District #37, BITD to prove the fluid, valving, shim stack setups off the pages. There were lots of shim stacks on the page at times but, it has been found to narrow it down to the shim stacks that work best for most. With a little understanding of spring rate and rebound control you can make a shim stack that will work for you the first time for the money at about $45 for fluid, $210 springs, $40 shims, $15 bladder, $15 Nitrogen, $40~$60 for home made tools, and a little more if you need seals, you have done the complete package yourself. You may not have the trick bottoming cone, gold valve in the end but, you will have a better suspension then most of the other shops at a savings to buy all the other gooies for your bike to make it fun to ride:ride:
I do believe that if you pay more for the same work you will tend to be happier with it. After all you paid big bucks it must be good!!!!
If you are not taking it apart and comparing it to what is out there you don't know what you have.

As always, a great write up. Had my attention the whole time.
I noticed that you are in Colorado. There are a few in Denver that can do your suspension for you. I had neil at Hitchcock Industries in south Denver do mine. A good job at a fair price. His number is in the book or the fellas at performance cycle can give you the number.
Thank you! I appreiciate all the info and feedback.
Noleen out of Heperia, Ca. did mine and it is great.
