Default Best mods for a totally stock 2008 F1000 Sno Pro?

Hey guys, picking up a super low mile unmolested F1000. Besides the Y-pipe what are some other bolt-ons that will really make it run? Does it need a clutch kit? It has the Cobra track in it and I donít plan to stud it, I like to tail slide corners and I think the Cobra is a sweet track without studs. Thanks.

Checking motor mounts and putting a torque link on it would be high on my list. I like a torsion spring in the secondary clutch, check that clutch bushing while you're at it, they are notorious

Best year for stock 1000 IMHO, torsional works well (1-2 more mpg for me) but compression works good too with a Fett Bros yellow/pink spring, stock primary is pretty good. I would add at least 100? (2 per pattern) studs but I like studs for stopping also. Lastly the best money I spent on my 1000 was a pair of 6.7 Pilot skis with 7.5 shapers and 4" whatever on the outside, no darting and like power steering.

If you can find one, Plowman mount to keep the engine in place.
Yes stock clutching is pretty darn good on the 08 but BMP torsional works just that much better.
Agree on studs, even heavily studded sled will drift the corners with ease, run down the center only.
Y pipe, works best with a fuel controller such as Boondocker, either way pipe means premium fuel only.
If it's a Sno Pro, dramatic improvement in ride ditching the air shocks for LXR version coil overs. Also good gains in ride quality having rears revalved.
Skis, after trying a bunch of em out there, settled on SLP / SLT for skis, also liked the Doo Pilot skis but lil too much push in loose snow. Loved the Simmons (tried both Gen I and Gen III but you do pay a penalty on effort to turn the skis on frozen hardpack.
Can't stress how much difference in clutch life you'll see keeping them blown clean between rides.
Be sure to remove the lower air box and add Gorilla tape to the outside where exposed.
While I really liked my 07 F1000, the 08 was a much better sled out of the box.

Aftermarket skis are a must

bdx diamond drive gears
4 arm primary is better than 3, but look for cracking on the inner sheave

Plowman mount on mine broke within the first winter. Doesn't matter. Sled still works great and doesn't vibrate like a mofo anymore.

Otherwise, the only things I did to mine were a y-pipe and BMP torsional conversion in the secondary ... works awesome. I'm also running Simmons Gen1 skis. Had this setup for 7 seasons now, and still loving it.

What’s the advantage of the BMP torsional conversion over stock?

It basically makes the clutch more "efficient", and you'll literally see a difference in fuel economy, since the heavy compression spring is thrown out and replaced with a spring that actually assists the "twisting" action of the secondary clutch. It's how all the old clutches used to work. Some guys have had success with the factory compression setup, but I just don't see the advantages of it.

Sorry, not much of a technical explanation, other than to say, the torsional is a more efficient, thus (IMO) more effective setup.

FWIW, my sled would ALWAYS beat my Dad's '07 F1000 at the pumps, until last year, we finally converted his over, and now we're basically identical (he's even beat me on mileage, which NEVER happened before). Unfortunately, we never had a chance for clean runs last year to measure changes in performance, but mine always out-ran his as well, and I do believe his was pulling harder as well, but again, never got a proper run to prove one way or the other.
