Ellet, you forgot the Cool Head of me in front of my CBR1000RR!! WTF man? That was classic!

As far as the "topic" if you bleed out the air you loose the progressive part of your valving...

This site is funny, glad I joined.
I had thought a pressure check valve would work sorta like the check valve on my compresser. Don't know much about them though. Smarter minds on here. Guess if it were an option, it would have already been done.

Almost, but I didn't want anyone to think you were in the same league of doucheness as Ol' 2k....

Let me see if I can find it.

I have to back up Jake on this, I rode 2 different bikes with this setup a few weeks ago and wont run anything else now.The initial part of the stroke is unbelieveably plush...the person that came up with this idea definitely knows what hes doing mechanically and this setup works.No problems whatsoever. Nuff said....

And Im sure your suspension doesn't bottom out either.... My suspension was set up to my liking before I installed these and I like it even more now

If it's that much better now, go down about 2 spring rates and take Slow Old Farts mechanical genius off of your bike

Twin Chambers FTW! I have Merge progressive compression valve springs along with Race Tech G2R valves. Super plush yet hard to bottom and still have the proper progressive air cushion...

I cant believe this topic is still alive........

like everyone said, if you want your suspension softer, revalve it and get softer springs. i can only imagine that now that suspension would suck ass on a track if you were moving remotely fast.

think whatever you want about this setup haha im doin what works for me...

And then when all the rear sproket teeth start all laying over due to wear, just flip the sproket and turn the chain upside down

With all this discussion, Supermoto Spike comes to mind. That's a depressing story I'll leave to someone else.

I stole this from here.

The theory behind sub tanks:

Sub-Tanks add a new dimension to the adjustability of your fork. The air volume in your fork is in effect an air spring. This is what helps your fork resist bottoming. Oil level controls the amount of air in the fork. The higher the oil level is the smaller the air volume making the air pressure in your fork ramp up faster on big hits. High oil level makes for a harsh ride on small bumps, but helps resist bottoming. Sub tanks allow you to run a high oil level and maintain a softer ride than normal on small bumps.

This is accomplished with adding back air volume with the tanks. Then controlling the flow of air into the tanks with a control valve. This system is more volume sensitive then speed sensitive. On small bumps, (like roots, rocks, and ruts), the smaller volume of air easily moves through the valve and into the tank. This makes the forks feel like they have a low oil level. On big hits , (such as whoops, g outs and jumps), the large volume of air cannot all squeeze through the control valve at once. This makes the fork act like it has a high oil level and will resist bottoming in the same way. With the control valves you have another way of tuning your suspension for different conditions. Open the valves for a softer ride. Close them down for a firmer ride. Sub tanks give a bike a plush feel without sacrificing bottoming resistance. I think they really shine for trail riding. But motocross and even supercross / arenacross guys love them too for chattery stuff like braking and acceleration bumps and ruts.

So, in short, the oil damping is a fixed rate thing as is the spring. The Air damping is progressive and provides you the ability to "tune" your suspension. By removing this element, you also remove your bottoming protection. A very dangerous condition if you think about it.

Let's go back to some simple physics. Say you have a nail, a standard hammer and a rubber mallet. When you hit the nail with the standard hammer, there is no give and velocity of the hammer is transferred to the nail. Hit the same nail with the rubber mallet and the mallet absorbs the energy and rebounds. Translate this to your forks. The air volume is the rubber component of your mallet, you are the nail. Without it, the first big hit you take, your bike is gonna drive you like that nail. If you are NEVER going to get airborne or take a high speed hit, you will probably be none the wiser. Don't be stupid. Eventually, you will find yourself in that situation and have forgotten all about what you have done to your forks. When that time comes, and it WILL come, you will be hurting in a MAJOR way and my conscience will be clear.

I'm looking at you Thurman...

16 years old...

Don't go buying into a bad idea just because "I tried it and it works great".
Motorcycle engineers designed them this way for a reason. Them Honda guys are pretty fuggin smart. Smarter than a 16 year old I'd wager.

Im wondering if I should go out and patent this awesome idea before Mr. Stewart's suspension guy hears about this and beets me to it?

CR500R7 · Post by **CR500R7** » February 25th, 2010, 10:59 pm

I wouldn't bother Ive already got the patent on that idea, soon I will be sending legal notice to everyone useing that idea or trying to sell it.
