Fork Rebuild

What are all the processes to rebuilding a fork. I got my forks rebuilt, and the technician told me he would basically revalve, seals, oil, discs, polish. Are there any other procedures to rebuilding forks??? I just got a Fox shock that probably needs looked at. Was there even a purpose of getting the Fox shock if it too needs rebuilt?? Could my stock shock worked just as well if it were rebuilt??

Sounds like the rebuild on your forks covered everything that would need to be done. The Fox shock should be an improvement on your bike due to the better valving, remote reservoir, and adjustability. And they are easier to rebuild than the stock shock.

Basically any fork or shock needs to be rebuilt once in a while because the seals and bushings wear out, and the oil will degrade with heat. So rebuilds are unavoidable if you want to maintain optimum performance.

The plus side is that if you have a good manual and some mechanical aptitude you can probably rebuild your forks yourself once a year or so. It's not very difficult as long as you are careful about it and follow the instructions exactly. Shocks are more difficult because of the heavy springs and the reservoir needs a high-pressure nitrogen charge, which most people aren't able to do themselves. I would send the shock to Race Tech or Traxxion Dynamics for rebuilds. Should only cost $100-$200.

Trevor,

Listen to R6racer. He's giving excellent advice. I replaced the inner tubes on my wife's YZF600. I made the "special tools" myself out of common items from, get this, Home Depot. It is not that difficult. I have been told that the Race Tech gold valve setups come with a pretty good video detailing installation. :)

Trevor this is something that you will eventially need to do anyway based on our off line discussions. ;) Once you have the tools and a nice clean, roomy place to work it isn't that difficult. It is actually kind of neat to see how it all goes together. :cool:

I agree that the rear shock should be done by a pro. They can be dangerous if you don't know what you are doing. We send the Ohlins forks and shocks on the race bikes to a pro for rebuilding. We change springs and spacers, that's about it.


PS. Make sure you have a factory service manual. I had the one for the YZF and it took me through detailed steps with pictures included. I wouldn't trust the aftermarket books. IMO :)

Pete likes pictures. :D ;) :D

Good luck,

Great, yeah R6 has some words of advice. I get the forks back monday, probably send the shock off when I get forks back. Cost $300, which includes trackside help. What the hell are you doing here John, what happened to Seca?? :) Are all shocks set at the same pressure regarding model of bike?? Example being: The Fox shock had 90 psi when I got it, the local shop found in manual that oem shock should be 140psi. Does this 140Psi also apply to new shock, or did I just get screwed with the wrong amount?? Yeah I want to see the innards of my forks, I should have taken them apart first before I sent them off.

The team owner and I decided that I would be of more help at the other races since Steve is not doing Superbike at Laguna. Due to my more limited vacation time with the new job and the new responsibilities, I am having to move my schedule more. I will be going to Mid Ohio and I currently plan to attend Pikes Peak,Willow Springs, and the FUSA finals in Daytona(Biketoberfest).

You should call Fox shocks. They should have a customer service line that could help you on the pressure question. I'm pretty sure that pressures vary with the size of the shocks cylinder.

Good luck and it sounds like your being smart in the racing stuff. :cool:

John,

Are you going to be at the Pocono FUSA round?

Tony,

I'm not sure. If the team goes then I probably will. It would be nices. That is one serious racing event. I was there in 98 with the Ferracci effort. It's a nice facility for racing considering it is inside an "oval" NASCAR track. Appears to be a very good fan track and you Penn folks take biking seriously. :cool: I'll keep you posted. :)

john,

if you come, let me know. pocono is a great event. too bad it's kind of ignored by the ama. hell too bad it's so narrow too, i think the racing would be better if they'd widen the one side a bit.

That's correct. That is who I was at the Pocono race with. It was a fun weekend. :)

R6racer,

I work with Grigg Racing, AMA #27 Formula Xtreme Muzzy Raptor. I'll drop you a line. Sounds good. :)

Tony,

I agree on all accounts. I really wish that someone one promote an AMA event there. It is safer than Loudon. It is one of the best bike events that I have been to in the US. :)

Plus forks should have an oil change once a year. If you haven't got it done, I would if I were you,
