If there is a way to regulate the fly weights in the PVT then it may be possible to make remove some of the major down falls of the system. Imagine having foot operated or hand operated lever. Normal position would be for normal PVT operation. The other position would somehow apply force to the fly weights. This would accomplish two things 1) keep the clutch engaged providing engine braking 2) increase the diameter of the front clutch durring cruising allowing for lower RPM's durring cruising.

It may not be possible to do this but you never know. I was cruising on a trail at a moderate speed and my tack was reading 5500 RPM's at half throttle. I would love to be able to somehow cruise at maybe 2000 or 3000 RPM's instead this would save me gas and perhaps allow me to have a higher top speed.

You would need a special PVT cover to start. If you can picture the operation of a throwout bearing for a clutch in a car.

Lend me your thoughts and opinions. Am i crazy ?

You are running 5500rpm at half throttle because they tuned the pvt for power and not gas milage. Personally thats the way I would like it. The user variable PVT is an interesting idea!

A lot of that is due to the way your clutch is set up. With the roller secondary and the proper pre-tension you should get decent engine braking. I know that I do on both the 400-2-stroke and even better engine braking on the SP500 w/o EBS. I think that belt tension is a very important issue.

The amount of rpm's turned can be somewhat controlled also. We have the new Heel Kicker flyweights coming next week for the 400SS. It's somewhat of an experiment, but it may offer some interesting results . . . stay tuned.

Thanks for being kind and just ignoring me, instead of ripping me. I should've read your other posts to know you guys are way ahead of me. I didn't really keep up with the atv clutching stuff (and EPI hasn't sent me an atv catalog)like I do my sled because the atv has to do work and the sled just has to kick A$$. They never seem to edit my posts when I make a real *** out of myself. Sorry for wasting your time. Maybe that semi manual/auto pvt clutch will work.
