Clutch engagement, why so high?

First off, I'm learning a lot here and I appreciate it.

My question, I have a 96 vmax xt and I've also noticed this on many other sleds, why do they have to rev so high (3500/3700) before the clutch engages? Is it because they're aggressive sleds or they need to generate so much power before they can move? I remember my dads A/C Cheetah and it engaged right away. Now that thing is 30 years old but I kind like that. Is this something I could set up differently on mine or something I just have to deal with unless I want to ride a 78 Cheetah?

Thanks

Thats actually a very low engagement. Its all a combination of the primary spring pre-load and profile of the weight. My drag race combo engages at 5000. Its not hard to change provided you are doing it with the right parts for the right application whether it be trail riding, short drags, long drags, climbing hills in mountains.

EDIT What type of riding are you going to be doing 90% of the time on this sled. We can give you a good clutch combo. Remember, your secondary works with your primary and both have to work together and not fight each other. You would also have to set up your secondary with the right helix and spring tension.

I will be doing 95% trail ridding, it does have a gyt twin pipe on it, just so ya know. I'm not sure if that matters.
 
my two Vmax's Engage around 4200 and my dads around 4500(diff spring) it is fairly normal and i believe has to do with building up enough torque vs, taking off at 1000 rpm and bogging down trying to move the heavy track in a lot of snow (sometimes it would work but not always)

Our old suzuki's engage low and wouldn't move if there was 1.5' or more of snow unless you stood to the side and got it moving and reved up first.
