Auto clutch

I know most of you guys are not auto clutch fans, however, given that I am an amputee, and dont have use of my right leg, I would like to have one.... I could use my left hand for rear brakes that way.

Having said all that, does anyone know if I can use the auto clutch off any other 660's like the grizzly?

There isn't nor has there ever been one available for sale. From what I recall they had some test units but never actually "made" them.

The 400-450 sized atvs that have them available in the aftermarket.

Consider tying both front and rear brakes to a common master cylinder, in your case on the right bar? Polaris does this with several of their sport quads - pedal is rear brake only, lever is both front and rear - the rear caliper, if i recall, actually has two hydraulic inputs - one from the pedal master cylinder, the other from the handle's master cylinder... a transplant of some of their hardware (say from someone parting out a Scrambler) might just do the trick for you.

I called Steve at QTS and he is awesome, not only did he help me out with my jets and new front tires, at a great price. But he is calling Rekluse to see if there is a way to make one work!!

Ok off my soapbox, but when I find someone who takes care of first time customers like this, I will let others know!

Thanks for all the good advice, if the Rekluse thing does not pan out I do have a 2nd lever I was going to mount to the right bar and run a cable to the master cyl. But I don't think that is as good as using an auto clutch.

im going with quad man on this one...and if you bleed the breaks right you can change how much the rear grab vs the front...i have seen racers do this before...they run no rear break master cylinder or pedal..the the caliper and run all 3 breaks off the front master cylinder..i have never rode a quad like that though...

My Scrambler IS like that...of course they have probably matched the calipers for properly distributed braking force as a function of fluid pressure...

See if you could rig up a perporsioning valve. That way you can control how much braking force you have in the rear.
