The precision tensioner is a nice piece.Thanks again! It's getting some basic service (mirrors, larger tunnel bag, tunnel protection) now before I pick it up at the dealer - it will be in again at Iantomassi in a couple months for studding, ECOtrail ECU, Snowtrackers. I think I’ll change the gear ratio to 21/38 with 84 chain and may spring for the Precision update to deal with the tensioner problem if needed - nice to hear they are fastened more securely now though. I can deal with any other suggested fixes mentioned here at the same time when the chaincase is open.
I can replace the exhaust bolts but it would be great if someone on here knows the spec. The sled is 2 hours away (Midland) from where I live (Burlington).
I'd be more apt to switch to a 22 top. I find that larger top sprockets are easier on the chain.
The factory exhaust bolts are stainless steel.

Exhaust bolts = M8 x 1.25 x 30mm length.

22/38 will not fit an 84 pitch chain; unless chain is stretched beyond service limits.The precision tensioner is a nice piece.

21/38 = 1.81 ratio. A 21/37 (1.77) will fit but big larger dog-leg. 1st pic 21/38. 2nd pic 21/37. Both with 84 pitch chain.
If you keep chain at correct tension, 22-37 works. If you don't watch chain tension, then likely you'll get chain rubbing on center post. NFG.

Yup, that will work.No, I meant use a 22 with the stock chain and lower gear.

Ok so if I play back your gear ratio / chain advice, my option is either 21/38 with the 84 chain or I can get close to the same improvement on top end by opting for the 22 top sprocket and keeping the stock 41 lower and stock 86 chain?  Both options have good efficiency with minimal dog leg. The second saves me the additional expense of the chain and bottom sprocket.  I spoke with TD about an ECU tune recommendation earlier today and he suggested I simply ride for couple hundred miles and the chain will naturally loosen up a bit to accommodate the 22 sprocket gear.  Does this make sense?  Thanks for being such a huge source of helpful advice...

21/38 = 1.81 ratio.
22/41 = 1.86 ratio.
Very close to same.
Yes, if you run stock chain a bit, you'd be able to fit a 22/41 and not have to buy a new 84 pitch chain and new 38 tooth lower gear.
Theoretically, a 21/38 uses an 84 pitch chain. A 21/41 or 22/41 uses 86 pitch chain.

Is this kit from Hurricane a good option to swap to a 22 top gear? Looks like it solves some other chaincase issues...

Just out of the crate so 1 year I suspect.  I didn't purchase any other options.  I'm still going to follow your original advice and install the shaft saver and simply ride it the first season to get used to it. Otherwise just installing cosmetic things like mirrors, scratchers, skags and a bigger bag...and also studding and protector.  I run a lot of ice on the eastern side of Georgian Bay so I need the studs for safety. You're welcome to join me...

I have that gear and shift pads in mine with no issues.
Also need to tack weld the screws that hold the roller in place on the chaincase tensioner.

I'm not saying that gasket isn't good, but I have over 10000 miles on my 19 and my oil tank has yet to leak and I run the stock oil blowby setup.
Nothing wrong with running mostly stock the first season.

Congrats on the new Winder.  Make sure to bleed the air out of the cooling system.  This tripped me up in my 1st year with the SW and ruined a trip due to overheating.   There are many threads on this, but basically need to get the front end way above the rear - run the sled -  open the cap on the overflow - push down on the rear end and get all that air out of the system.   Some dealers do this prior to delivery. Many do not.
