Continued clutching theories...

All that being said, ^^^^ where the mass is placed in a cam arm will have a similar but more finite effect on RPM. Moving the mass around from toe to heel will effect how aggressively, or lazy the shift takes place, and where it is aggressive/lazy in relation to point of clutch shift... is the belt in the bottom 1/3 of the clutch or somewhere in the upper 3/4.

WOW ???? membrane???? WTF???
The only part of this that is somewhat correct is "making the roller work harder"
The only similarities between the adjustable cam arms, and the TRA clickers, is that RPM's can be adjusted with both fairly easily. While both change RPM, they are not doing it in the same manner. One is changing total mass effecting RPM (cam arm), and the other is altering ramp profile to change RPM (TRA).
In order to have the exact same effect, you would need to be adding or subtracting mass from the pins of the TRA, as you add or subtract screws from your cam arms... IE... changing MASS!!
If you wished to change the RPM in your "Comet Clone" (p-85, Cat, Yamaha) clutch, in the same manner as the TRA is altering RPM, you would have to grind on the roller contacting face of the cam arm. Thus changing the "Shift profile" of the cam arm, effecting RPM.

What is the roller attached to ?

You can be clicker 2 or clicker 5 and your engament and up shift will not be effected at all if all other parts are working accordingly.

umm???? the membrane ???

We agree that the roller is fixed to the arm and all the roller does is holds pin weight and allows the arm to travel up and down the fixed ramp....so wouldn't agree the arm is doing all the work ?

If your clutches are shifting out all the way your track speed is going to be limited to your gearing, the only thing changing ramps and stuff would change is how fast you reach peak track speed and at what RPM you are running when you get there right?

Correct!

yes, we agree the roller/arm is doing the work.

The arm more the roller. The roller is just a necessity of the arm. With out the roller the arm wouldn't be able to glide very we'll up and down the ramp profile.

Ahh changing the clicker changes the ramp profile, even tho it's the same ramp it gets steeper and shallower by changing the clickers, therefore the profile changes.
Remember newtons laws of force??

Without the bolt holding the clutch to the crank taper it wouldn't work.....so the bolt does all the work.

and DPG on Vac ca again....
same as cat weight profile it is all load location, spring pressure and...rpm. but lets not forget the guy controlling the load on the motor mr driven clutch. helix and spring... and the the 3rd player in the game the gears. the belt pays the check if all are not happy.

And what were we talking about? Oh. How much money we want to spend to achieve the results desired. Btw, They are all good when calibrated the way we like them to work. You know what is really cool though is that good clutching makes a little motor think that it is a big motor and a big motor think that it is bigger. ie.[altitude, snow conditions, terrain, weight, etc.]. Oh yea. There is the secondary, gearing thing too. You know it's snowing out don't you?

TRA

Keep on mind all ramp profiles are not alike. In the mountains and deep powder we like steeper ramp profiles so the ramp/roller arms have to work harder to stay within the peak torque of the powerband best suited for steep and deep mountain riding. Dow in the flatlands ramps profile are usually much flatter which allows the TRA to shift into an overdrive sending the cruising at over 100 mph down the trail on an 800 etec. Same motor steeper mountain ramps same 800 eye motor @ 9000 feet in the deep powder 55 mph top speed....you can clutch and gear you sled many ways for the style riding you do.

DPG

Actually almost all of Ski-doo's flatlander calibrations have taller ramps at full shift than any of the "mountain" sleds....the 414, 413, 410, 412 in mxz's are all taller than the most summit calibrations. The flatlander sleds are geared tall and most don't run into overdrive...mxz 800e geared 27-45 stock and usually goes faster slightly geared down. There are lots of ways to tune the tra to the correct peak rpm, but as posted some ways are much "quicker" by taking advantage of the correct power at the correct gear ratio at the correct rpm at the correct millisecond. That's why some kits work better than others.
