Auto-clutch for the 400?

I have a few questions,

Is there a company that makes a auto-clutch kit for the 400ex. If so where could I find it, anyone with a link? Has anyone tested it out yet? stuff like that.

I am curious because my girlfriend seems incapable of learning a clutch.
...and with the release of all these new quads 400ex prices have dropped a bit, so I was hinting to the "wife" to buy an ex, something with decent power but nothing she can't handle.

She just wants a good sporty looking quad, to follow me around with and I figure a 400ex would be a good machine to learn on and bag on for a while.. :)

EFM makes auto clutches. I talked to them at the last GNCC race, they are making one for the 450r and the yfz450. I am sure they make one for the 400ex. Here is a link to their website. They quoted me $500.

Thanks a lot guys, and if I can convince her to, I will definately tell you guys how the thing works. :)
why would you want an auto clutch????
wouldnt it give you less control of your machine??
Here is a thread about auto clutch kits on exriders.

I have tried and tried and tried to teach her to use a clutch and she just can't grasp the concept of it, so an auto clutch would work for her, she isn't a hard core rider anyway.
i read farther down the thread and one of the guys has it on his 450r. he likes it alot. wonder what that would be like?
oh i see.....
how do they affect the power?
im sure there must be a considerable loss

I cant see why there would be a considerable loss in anything.

Maybe just the type of take-offs you get.
Is it just an auto clutch or auto transmission like the KFX???
its a clutch kind of like the ones we had on our gocarts when we were young.
also it could be cool for you 2 stroke guys that like it when you let off the gas and you just keep coasting. im sure its the same
i think the only power you would lose is when you let off the throttle to shift
