Took it out for the first time today, wouldnt engage from a stand still until about 4500 rpm. Will a stiffer clutch spring be the trick?

Stiffer will engage higher, less starting weight on your spring will engage earlier.
Also check your primary spring, look if it is hanging up in the spring cup, you'll see wear marks on the side of the spring, my sled jumped from 3500 to 4000 because of this. If not, then get a shorter primary, or at least one with less initial spring pressure. The after market springs are slightly narrower and that should help with them hanging up.
Like I said, first ride on this M1000- where should it be engaging at for RPM?

I run the SLP black/yellow spring and get much more consistant engagement around 3650 over the inconsitant stock engagement that floated between 3750-4000rpm because of the stock primary spring binding in the cup. I found the lower engagement better on these motors as they have the torque to pull it along with the Diamond Drive setup to get up on the snow easier without trenching from take off if your running the higher engagement spring. Makes deep powder riding that much easier to take off in the nasty situations. The stock spring causes the track to engage so violently you are pretty much garaunteed to spin off the take off in every situation including pavement or hard pack snow conditions. As mentioned the aftermarket springs sit in the cups better with no binding and way more consistant performance as well.
Springs have got TWO rates. Basically called a start rate and a finish rate.
I'm not running a turbo, don't know much about clutching them but can offer a bit of help I guess...
D&D White - 135/330- this is what I run on my m1, the engagement is pretty nice. Not sure if I like the high finish, I noticed I had to tighten the secondary quite a bit more to make my rpm. You'll learn that clutches are Voodoo!
Cat Orange/White 143-290
Cat yellow white 122-285
Cutler makes a low engagement high finish but I haven't tried it yet
cpc- gold white regular 135--305-
# CP-000-0012 Titanium Gold/White Engagement Spring 130 @ 2.562” and 320 @1.312” $100 discontinued
Also haven't tried any speedwerx stuff, probably give their new springs a go next season as they should be replaced every year. And 'cause there's nothing as nice as a freshly rebuilt clutch. Buttons, weights, pins, bushings, a milled out spider, DD rollers, belt, springs Mmm MMmmm Good!
What primary weights do you got on the go?
