Does any one think there mountain max gets bad gas mileage? we did a 45 mile loop and waisted 9 gallons of gas and our polaris only waisted 5. Is there anything wrong with it?

That doesn't seem right! That's terrible mileage. A friends older Yamaha 750-4 cylinder with 4 carbs wouldn't use that amount of fuel. Sounds like somethings wrong, not sure what.

either got a gas leak, have extremely large jets, or the Polaris is stealing gas

would prolly make sense if you were riding heavy snow or something that made the engine rev high a lot.

That sound right if you were really getting on it in very deep snow. I have a 2000 MM 700, and ridding into our cabin, about 45 miles; I will burn between 1/3 and 1/2 of a tank with some playing. I have used a tank in 42 miles but that was ridding in very deep snow and climbing a lot of hills.

Snowmachining is not a thing to do - its a way of life

Ride Fast my 99 MM700 does not have 'smart carbs' if you mean High Altitude Compensators.

I recently went out on a day trip with my other 2 XLT 600s and we all used about the same amount of gas. 35miles with about 4gals. Most of that was off trail so we were working them pretty hard.

Well it looks like I have to correct myself. 99 MM600s did have the smart carbs

Still my mm700 does not. I'm not familiar with the option but I would expect you should have similar fuel mileage to mine or better being a 600.

Is it stock motor? Mine has Bender triple pipes. I've no idea if there has been any other motor or clutch mods on mine.
