This is just my observation on the fabled "maverick belt" I paid 130+ for it of amazon. It's the new part number from a 2015 Maverick 1000XXC, ends with 364 instead of 702, same belt just updated part# from can am.
I have always run Gates on my Outlander up until my recent build up, during which multiple sources told me that my Gates Carbon series was trash, wouldn't hold up yada, yada, etc. so I bit the bullet and tried one.
So a little background on my build, it was a bone stock 2013 Outty 650 w/dalton clutch kit. Now it has an 850 big bore kit, Ported maverick heads, 2013 1000cc camshafts (1000cc has 245/240 duration instead of 800R's 230/240, both have same max valve lift)
Port matched intake manifold to both heads and 51mm Overbored throttle body, HMF Titan QS pipe, and PCV with the AT dual wide bands. My factory Primary had already bit the dust when the bolt went bad allowing it to spin on crank till the aluminum had changed to a nice gold color from heat, so I opted for a QSC Rev X primary, Adam at QSC is awesome and their customer service is second to none.
For reference my last belt was a Gates G series Kevlar(350+ mehh... miles) which was definitely not as good as my initial Carbon series gates (1100+ great miles) that I pulled off basically to trying test them out for my self, I installed the maverick belt with the new primary.
So I told Adam about what I had and he set up the primary initially, and my belt, after giving it an easy break in, would only hold when it was cold the engine would rev to about 8250 and hold, but after a few miles the belt would slip constantly and rev to the moon 8750+ if I pegged it. I would get a nice blast to my face with a melting hot rubber smell from the snorkel pretty much everytime i gave it any throttle even just cruisin pullin a steep hill. I should also say that the acceleration above 40 was even worse than the stock 650s, to the point of being almost nill, but only when the belt got a few miles of heat in it.
So I called Adam, and he confirmed my issue, so I ended up stuffing the heaviest slugs into each hole except 1, the second heaviest went there lol. Take the bike for a rip, and now it pulls like and 850 should, belt grabs cold at about 7600 and holds, but when hot grabs around 7800 but it at least holds there, no hunting around, and I don't get anymore really hot belt smell from snorkel, just a mild odor.
So here was an interesting finding, when I pulled my Maverick Belt to change the QSC weights out, the belts consistency had changed from when it was new, it was very stiff, but now it was pliable, gummy even, but not glazed or cracked. So I grabbed my lightly used Gates G-series Kevlar belt, to my surprise it had the same damn gummy squishy consistency, which spurned me to grab my well used Gates C-series Carbon belt, which even with the highest mileage of the three was still markedly stiffer both, torsionally and laterally.
To that end the Maverick belt exhibits the same flaws that made me unhappy with the Gates G-series Kevlar belt, inconsistent performance; changing shift-out depending on temp, lack of power holding, slipping, etc. I felt like I got taken to the wallet cleaners so I did some digging and found that both of these belts us an "aramid fiber cord", and the only real difference is probably the "proprietary rubber compound" surrounding it.
So for now I'll run my Mav belt for a bit, then I am gonna swap my used Carbon belt back in for a true apples to apples comparison. If it does the same then the only other belt I know of to try is the one from EVO performance...
I will be going on the 150 mile hell run next week so it may not be long lol.
