1. Cal Spa Supra Manual

So I've got a Marzocchi EXR Pro Coil on my Kona. The thing is nicely made, but it lacks so much adjustment.

The forks are EXR Supra. 2006 Owners Manual: Marzocchi lubricates the dust seals of its forks with grease to help. 0 Comments Debt Collectors Training Manual.

All it's got currently is dual preloaders for the coils. Not only does is there no damping adjustment, but there appears to be no damping mechanism at all. Doesn't feel like it and doesn't look like it inside. Now, I know that forks can be upgraded and 'frankesteined' in certain ways. For example, I know I can take the coil out of one leg, install an air filler cap and turn my fork into an air/coil fork. How far can I take this?

There is an oem fork in the line called an EXR Supra. Superficially it looks just like my fork, but it has adjustable rebound damping in one leg. Would it be at all possible to get ahold of that cartridge and install it in my fork? My fork has saved my face on several occasions, but I'd like to get some more control over the action so this would save me from having to buy a whole new fork. I have the same fork, and of course interested in other replies you get. It has damping, you have to change the oil viscosity to change the rate. I keep meaning to call and see what weight oil they use, also how much.

I would also like to find out how much more oil you could put in over recomended, because ALL forks are air forks in a way. When they compress, the air above the spring (and oil) compresses. Putting more oil in, reduces the room for this air to compress, raise the spring rate faster as the fork compresses. But if you put too much in, you hydro lock the fork before you get the full travel out of it.

So yes, I would like to know what I can do to this fork to tune it also. Now that you mention it, that has been the correct advice on such a broad range of subjects that I'm sure you're correct. Serious I can't remember how many times I've told someone to not waste money upgrading their X, and just save to buy a higher quality X. After which they can sell their old one and be better served in the end. And here I am tring to upgrade a 200 dollar fork. Thanks for the bonk on the head! Now, to get the most out of it while I save for a new one.

Can anyone tell me how oil weight can affect damping when there is no damping mechanism? Xerox 6360 printer driver. I keep hearing I can tune it by oil weight, but if there is no stack to resist the oil then how would this work?

Sorry to trouble you but for the life of me I don't understand the tech manual for the 2004 marzochi exr supra forks (120mm). They have a coil spring in the left hand leg (As sat on the bike) with an allen key adjuster on the top of the leg. The right hand leg has an air valve on the top and an external rebound adjuster on the base of the leg. Question 1 how do i set the sag? Question 2 is this classed as a spring fork or an air fork as this makes a hell of a difference to the amount of air in the right leg according to the marzocchi pressure tables 0-15 psi for spring fork 35-45psi for air forks (80kg) Question 3 Does the rebound adjusters make a lot of difference to the speed of damping return as fully turned either way it doesn't seem to make any difference. If you could point me in the right direction I would be very grateful as I am a bit of a newb to the game but don't make me go back to the pdf please.

I know this fork well First to set sag - Screw the sping preload in so it sits flush with the top of the sunk section of the section that is covered by that bit of rubber. This gives you a neutral spring, with a choice to add more spring, making the fork ramp up more in the end of the stroke. Or less, allowing for a more linear travel, once you have set the sag. Now set the air pressure, and the sag. It is an air fork with a spring that controlles the characteristics of the stroke. Set the air pressure to set your sag. You should get about 30% sag.

Now you can fiddle with the spring settings to get the feel of the stroke right for your riding. All of that said I run the spring preload quite hard, and a lower air pressure, because the fork is smoother and has better small bump sensitivity in its early stroke when set up this way. The rebound is quite effective, though be careful when adjusting it as it is quite delicate inside.

Adjust the rebound so it is quite fast. I agree there isn't a great deal of difference at both extremes, but it still coveres enough to make it worth setting up correctly. Whytepeak Thanks for that mate I Have just serviced the forks with new seals, oil etc. As I think they have been there since 2004. I bought the bike a few months back and are currently working my way around the servicing. When i put the forks back together they seemed very very different so thought I would check the Marzocchi web site for tuning/set up tips thats when the trouble started!

I could not sus whether they were spring or air. They are not that good at explaining what order to do things in. Thanks again borderboy.
