600 clutching

[beamslayer]

I am helping my friend out on his 07 600 rmk and trying to fiqure out his cluching.It has a 64-44-46 / 64-40-46 helix black/blue spring 3 delrin washers a white primary spring and 10/58 wts stock gearing slp pipe and can. We ride at 3000 to 6000 ft tress and clearcuts.Can someone explain to me how this set up will run.Is this set up more for racing or boondocking.Should we be looking for a lesser starting angle.
Thanks JIm

Flatland, low elevation setup for racing. Run a bit less helix.

That helix sounds pretty close to whats in my IQR. Should be eally fast in a strait line drag race setting but probablt not the best for boondocking. Starting angle near 58 should work great

I just ordered a 56-38 .36 for my 07 600

Agree with above helix and also confirm gearing, these 600's like some lower gearing. 19/43 works very well.

So a 56-38-36 helix what will that do for rpms compared to the 64-40-46. I am having a hard time getting my head around this.What is up shift, backshift and loading the motor mean in relation to each other.
