When competing? Are they letting you run a belt drive in hill climbs? Whose rules are they using
Really? I'm pretty sure that's not true. Todd and Trace Tupper from Tupper Racing are running the MVM belt drive and they are part of the RMSHA circuit. There is a hill climb this weekend in Bellevue, ID they are participating in.
TKI Belt Drive
TKI! Fit&Finish,made in USA, customer service. I've had two TKI belt Drives one on a custom built pro-lite 940cc and now on a CPC Turbo 800 w/162 3 inch track.

Not the same comp Wyo is talking about. He is not hill climbing. It's the back country comp he did in steam boat co last year. They were supposed to have more events this year but the the first two have been canceled because low participant sign-up.
Yeah I remember reading about that. He won the competition if I'm not mistaken. I guess my point was if they all the MVM drive in the RMSHA circuit, I can't imagine they wouldn't allow it elsewhere?
I am looking to add a belt drive to my 2015 M8000. I was just on TKI's website and see there are upper gear choices from 24 to 30 tooth upper gears available. I may wait a bit until I can combine the belt drive and a 3" Powerclaw at the same time. I plan to continue to use the 8 tooth drivers with the setup. My question is, what upper gear should would be best to work with this setup? My sled is a 153' and has the SLP single pipe and can with MDS weights. I weigh 175 lbs. without gear and I ride from 4-7,000 feet the vast majority of the time.
Also, I am not married to buying a specific brand but, are there any of the manufacturers or distibutors that are offering a late season special?
Why do the manufactures speak in upper gear sizes when everyone here seems to speak in terms of gear ratios?

What classes are they allowing a belt drive in? I got told no go with belt drives in Alaska and they use isr rules

Rules?
In the midwest I can run both the Cor series and the MASTERS series with it...However I would not suggest the MASTERS....Not to highjack but what is the backcountry comp? Link??

Why in the heck would ut even matter, belt drive or not? Seems screwy!
On my 14 I used 25/63, 2.52 ratio; 2.6/162/8 tooth drivers. Equivalent to 20/50 gears. It worked very well.
My Money goes to C3, TKI does not even use the correct tooth form
These are a few of my observations from a TKI for sale post that had very high quality close ups of the sprockets.

I noticed the round root of the tooth profile and when I compared it to the Gates and Mitsuboshi Carbon belt and my C3 sprockets I noticed that the TKI is indeed running the wrong tooth profile for the Gates or Mitsuboshi Carbon belts. FWIW
Glad I went with the higher quality lighter weight originator (C3) for my sleds. The correct tooth profile closely resembles a true involute tooth form. Flat top and bottom with a constantly changing arc connecting them. The Gates tooth profile slightly more pronounced than the Mitsuboshi.
The TKI tooth profile can and does work, just less efficiently than the true / correct tooth profile. The rounded tooth does not engage the whole belt tooth, it point loads it at the top near the carbon tension / tensile members which could cause accelerated belt wear and lead to belt tooth stripping if the correct conditions were to present themselves.
I can not speak to MVM. I'm a Polaris guy and been dealing with C3 since before TKI was even making sled parts. FWIW

Love my TKI. Tom is a top notch dude. I thought maybe there was more on the table with my sled after I had the belt-drive on for a couple months and Tom sent me another sprocket to gear the sled up no questions asked.
Install was cake and have had zero issues in almost 800 miles. 5 of my buddies also installed TKI on polaris and ski doo and not one issue with any of them. I'm a TKI fan for life.

Belt Drive
Now that we've heard most guy's are happy with there purchase, I would like to here about the economics. weight savings? cost per lbs.? Thanks

This is one of those mods that are really a waste of money. Have had both on the same sled and you can't tell the difference plus then its another spare belt you have to carry.
Most do not carry a spare chain, so why carry a spare belt? They are every bit as reliable when installed correctly. IME
You can carry one, but the chance of actually needing it are less than 5% and most of those are owner / installer caused.
I disagree with the waste of money opinion as well. But I've been waiting twenty plus years for belt technology to be able to deal with the shock loads a sled can dish out. Now that they can and do, I'm all in! With my choice going to C3. Hands down the best of the 3 choices. IMO

I always thought of it as more of a reliability thing....also when a chain goes, its usually pretty damn destructive and takes out the whole damn case and the oil tank too. I figure the cost of that little ordeal pays for the belt drive right then and there, atleast real close if not...Then your dead in the water! With the belt drive it breaks then what, put on the spare and boom resume your day like nothing ever happened. Thats how i always looked at it anyhow. I dont run a belt drive either, wish i did! I can just barely aford my monthly payment on the damn sled.....another thing with running a chain is its such an unknown as to whats going on inside that case since you cant see the damn thing. As with the belt drive its just right there in the wide open, no stinking trip ending suprises.

Not a personal cut to you or anything sandman, but this is kind of like when guys say aftermarket shocks are a waste of money because they can't really tell a difference. Some people can and some people can't. If stock works for you great!
My 2 cents
First off, I have not run MVM's or TKI's version of a belt drive. I do however, have a C3 drive on my 285hp M1100T with 3", my Arctic Edge 925 M800 with a 3", and on my wife's 2013 ProRMK with a Carl's Cycle 660 and 2.6" Power Claw. To date, the 1100T has 1700 miles on the belt, the 925 has about 2000 miles, and the Pro has about 1100 miles, all mountain riding, not one belt failure, and I haven't replaced any either. C3 did their homework, the system will withstand tremendous shock loads and big hp, but like anything, setup and installation is key. If you miss the sweet spot and have the belt too tight or too loose, it won't live. This is my personal experience. Would I buy another from C3? You bet.

5.1 oz belt
9.8 oz oil tank
1lb .8 oz bottom gear/bearings
1lb 4.2 oz cover with powdercoat
15.4 oz lower tensioner and bolts
