    I have just finished doing some testing of my Infinity Subtanks on my new 640 adventure. My company makes these and this is kind of a plug but this is a different application for these things and I wanted to show it off. Because of the tons of crap under the fairing the best place to mount them was on the fairing/headlight frame. I am trying a new setup with ball valves instead of the adjustable control valves I normally use. This is so I can switch the system off for road riding and on for trail riding with the flip of a switch. I am running a 100mm oil height with this set up and it is helping control fork dive while road riding with the valves in the fully off postion. Turning the ball valves to the fully on position is really unrestrictive and has the feel of dropping the oil height down to a much lower level. So on the trail that make the forks more sensitive and has eliminated a lot of deflection in the rocks. The ball valves are not ideal for Subtanks. But they are really easy to use for this application so I am considering offering it as an option for a dual sport setup.

    Interesting stuff Zero. I visited your website and read the theory behind the system.
    Makes perfect sense and would seem to be a solid solution to a DS bike set up with stiff springs for off-road... that are a bit harsh for the street.

    Would you mind providing a more detailed explanation on your use of ball valves as opposed to the adjustable valves?
    Are the ball valves a better control device in this application... or is this more an experiment on your part?

    Thanks,
    C

    The ball valve thing is kind of an experiment that I think I really ended up liking for my 640 and seems suited to a dual sport bike. Subtanks excel at smoothing out smaller bumps that normally jiggle the crap out of you. Things like washboard, roots, rocks, and in your application Creeper potholes, seams in concrete roads, manholes, etc. They can help compensate for heavy springs or stiff valving. The ball valves differ from the control valves I normally use on a dirtbike set up a few ways. The first is they are very unrestrictive. So when they are open they are really open and the effect is similar to dropping the oil height a lot with out having to do anything but turn the tanks on. But on big hits the system still does help bottomming. Because you can't count turns of a knob you can't fine tune the ball valves easily either. It is more of a course adjustment. On, off , halfway. The second thing and best thing for a dual sport application is they are instant. You can turn them on and off in seconds while you are still seated on the bike. Dual sport bikes are a compromise on a lot of levels. The Subtanks give you 2 different fork setups with the flip of a switch so it makes your suspension set up a little less of a compromise. For me I like my suspension on the street and I like the front to ride high on the freeway. The higher oil level helps keep the front up in the travel for highspeed stability. With this high oil level the small bump performace is sacrificed offroad. Offroad I flip the valves to the on position and it smooths out the washboard and rocks. And in canyons on pavement it is cool to have the tanks on so the front really sucks down for cornering.
    Here is the link to my theory page so you guys can see how and why subtanks work. http://www.infinitymachineanddesign.com/Theory.htm

    Awww crap Rob... now that I already ordered the subtanks with adjustable control valves, I read this and start to think that the ball valves might be a better way to go. :huh

    Mentioning that there is an on/off and an "halfway"... and that the flow values are better makes me think that the adjustable control valves are not going to be all that advantageous over the ball valves.
    I guess I'm after a "firm/soft" setting myself... just for different reasons.

    Tell ya' what... if you think the ball valves are the way to go for me, I'll give 'em a try. :thumb

    I think you will like the ball valve set up because of the ease of use. The control valves are pretty easy too but they are not as quick.

    OK boss, you convinced me... ball valves it is. Three positions from the seat sounds better than infinite positions you have get off the bike to match from side to side. :thumb

    Yeah yeah yeah... you already know I'll do a full gonzo installation write-up with initial performance impressions.

    :nod I know technically I will neither need nor want more than is to come.

    This time I would like more psychology. The Infinity Subtanks made me feel ___________.

    Ah "bulletproof"? "smart"? "sexy"? "younger"? "taller"? "well-hung"? As Mike Meyers used to say... "just like a little girl"?

    I give up, what?
