Its not ratcheting, its a clunking sound when the track starts to engage. IS this normal? It does not ratchet.

Ice build up? How many miles on the sled, could be a belt.

No, its only got 100 miles on it. Its bnand new. Seems like to me that its got a lot of play in it between when the belt engages and the track starts to turn. Its clunk then goes.

X2,
I would start there. Adjust the chain tension (make sure you rotate the secondary to pull out slack on the back side of the chain), finger tight and then 1/4 turn out.
Even after doing this it is common to get a clunk when taking off after coming to a stop that required heavy use of the brake.

It's just your sprocket teeth hitting the track drivers. If you look inside your track by where the sprockets are you'll see that there's slop on one side of the drivers. Someone else stated you'll notice after hard braking and that's because the track has moved relative to the sprockets and is tight against the drivers in the braking direction. When you get on the gas the sprockets spin a tiny bit and slap the drivers on the track. It will be more noticeable when the track is loose and close to ratcheting.

If snow conditions are right, ice chunks on top of the track can build up and rattle/clunk around up there. Also, since it's brand-new, maybe the secondary moveable sheave is sticking open when you stop which will give a slack belt on take-off.
My guess is ice too if this just started after it was fine when rode it last.

This slack in belt take off was a problem for me when I switched to four strokes. The secondary will not close as easy as it did on ALL of my 2 strokes if you are on the brakes. My solution....don't use the brakes. LOL. Honestly I have found that I rarely use the brakes with the engine braking now. That lever on the left handlebar is only for emergencys. LOL. Then I expect that "CLUNK", when I take off again.

I always let the sled coast to a stop, allowing the belt to ride back to the top of the secondary...no brake. At take off, throttle up gently until the clutch engages and then have at her.

I agree, have had a few occassions of breaking to stop and secondary not fully squezzing belt to top. Not sure I would call that a clunk, more of a delay, need to rev more than an unusual sound......+/- a clunk.
Where I do hear clunks is with the 06 monoshock accross slow bumpy areas.......this is normal and sounds bad. I have had a buddy come to me after trading sleds saying something is wrong with the skid.
Good luck.
