I noticed my engagement was higher when revving it on the stand too but when I took it out for a ride I never noticed it at all. For track tension just set it to factory spec.

The new weights for the lower elevation are super accurate when I weighted all 3. These are the Mountain Mod Indy Specialty weights for 2020, still lots of room for more magnets if you add more power, and of course easy to take out weight to dial in perfect RPM when going up in elevation. When I weighted the 3 weights in the last pic 2 were exactly the same the 3 was 0.1 gram different That is precise! 1st pic below doesn't have all the magnets in and 3rd pic also has 3 magnets holes open when I took the pic.

Your engagement will be different slightly on the snow than the stand. You can adjust it with placement of the magnets on the adjustable wights or from changing the primary spring. Springs are cheap and some of us keep a few around to dial in what we like (everyone has a slight different preference) I like a smooth engagement on the snow when Im in the trees for example that lets me be picky with lines without trenching. Same sled if I was still racing hill climb would be a much higher engagement that would absolutely stink boon docking or in the trees. It's funny to me when I have someone switch sleds with me for a few minutes so I can "see how their's rips" they tell me and they have it set up like a snowcross race sled and cant figure out why they are stuck all day
damx can you post the Indy specialty Mountain set up the same way as above?
These snow storms in Upper MI have trees down everywhere! Took a little rip out yesterday and caught some branches from fallen trees and was also glad I had the RSI hand guards on, Im impressed with how these flex and retain their shape plus saved my knuckles from some whips.

So those are fully loaded at 71g? They cant be 850 weights if thats all they are for low elevation?
No, there is room in each hole for more magnets, I was just showing that pic as an example. I use a sharpie on the scale so I place them in the exact same spot each time to get the most accurate weight.
that weight has some material removed, the low elevation(trail)weight does not have that. Mine came set at 3-2-2-2 which is 73.5gr on the scale.

What elevation are you running at?
800ft
Mine came set the same way, I took the pic above when I had some of the magnets out. I should have specified that it was just a reference pic. I do a lot of riding in Upper MI around 600-1000ft.

Im at about 1800 ft and I think mine came setup at 76 grams. Green/black primary, red/ light blue secondary and the helix is the trail version 62 or 66.
Don't forget to clean your belts when they are new! They still have the belt release on them and will glaze your clutches. I use Hot soapy water and a scotch bright pad. Make sure the dish soap doesn't have lotions or oils! 
After I got my clutches balanced and machined at Indy Specialty it was time to instal them and alignment with the TRS-TKHS bar. Mine from the factory was way off. This is easy to do follow Tonys instructions if you haven't done it. I have a number of Polaris bars, but I like the way the TRS bar aligns with the primary on 4 points. This is an easy way to pick up some performance and extend the life you your belts! 
Mine came with the same springs. They have a number of different helix's, mine has the Mountain 1 RCTS-Full. If your swapping helix's it's a Torx T-27 not a T-25 like some use. They have thread lock and might strip. If they are hard to remove heat them up with a heat gun or a low flame propane torch.

Yup. I have a t27 thats well used from helix bolts lol. I always heat them up before even attempting to remove them. I am wondering about the weights though. The sled isnt even broken in yet - 80 miles or so - and with this clutching setup I can 8400 on the hard pack. Gonna try it tomorrow in some good snow. But if I need to add more weight, I have no more room for anymore magnets.
I hit 8350 to 8400. So will add a magnet and go from there it flat out rips ..trail weights ..turbo3 helix..160/240 spring and green primary. You can also drop the finish rate on the primary . But test in powder not on trail. I test in powder with a good load on the track cause thats when you want proper rpm
When your switching out your track. Add a little heavy duty vinyl to the bulk head. It will help minimize ice buildup.
I use Bleach White to clean it up. It may take a couple applications. Then a complete cleanup with alcohol.
