Lets hear some creative home build ideas

Put indy dans clutching on a stock axys.

Instant ski lift in any situation / maximize trackspeed for a given throttle input.
Backshift to “first gear” in an instant, then spool up the track to 40 mph a second later.

It’s all about proper calibration.

You can hold your hand on the clutches after a hard climb.
(For reference I cannot hold my hand on the transmission case of my ninja 636 after a hard climb ??)

As much as I like riding this thing every time the track isn’t accelerating (shifts) the momentum needed to make the next turn/ climb/ cliff etc. isn’t happening.

Yes i can rev it, slip the clutch, upshift/ downshift etc.

Cvt by definition will apply power to the ground more often and with smoother power progression (traction) than a manual gearbox.

Now compare to a stock sled from 2006 ish?
Clutching is trash, sled drops rpm with increased load, recovers slowly.
Belts are constantly wearing out, you can cook an egg on the clutch.

Can you describe what Indy dan does that the big mfg can’t seem to get? I’m still sure I don’t want one, but I’m always interested in power transmission designs and find them fascinating. The sled cvt is a neat form of power trans, with the main drawback of friction.

Indy dan does not publish the helix angles/ cut / spring rates.

I think he does black magic.

(Also potentially copying TRS clutching theory)

Light springs, light helix = shallow
