Yes this will cause you gas milage to suffer bad.The beldt is narrow so there for you have to get the rpms up higher then normal for the same amount of belt squeeze to go.

That is going to be tuf in all conditions you will run out for sure. Yes carry more gas but you should be getting gas no further than about 125 miles standard tank. You do have the wrong sled Vector FI would do what you want.

I'm going to start a new post for the belt and clutch issue. I think I have the issue with the milage in hand. thanks for all the help.

I agree with what whitedust said...get the VECTOR FI..you just won't have the top end...I was always the one who had to "re-route for gas" in my group...my crossfire, running hard in loose/deep snow got around 8 mpg..on groomed trails, taking it easy I got 11 mpg..with my attack pushing fresh deep snow (12-16 inches)..I still got over 12 mpg..something ain't right with your sled...and I would say that belt is it.
Hey Whitedust..I finally got some riding in on the attak..LOVE IT!!! Best move I ever made. You are right...the mono is a bit soft gonna try some different settings...might have to get the big boy spring..other than that love it.

Yep 06 were soft. Harden as much as you can within spec limits & if does not work bigboy is way to go.

And you never will.
You're sled is heavier and the Genesis 1000 is a detuned high performance, actually a detuned racing engine design.
Any engine that requires higher RPM in order to make it's power, will be less efficient, meaning it will require more fuel (BSFC) per pound of torque produced. Engines are simple air pumps which require fuel added to air in the correct ratio to make fire. The faster you spin the pump in general, the more air the engine produces in CFM, the more fuel it needs in order to maintain the correct A/F ratio to produce power.
The Rotax is a lower rpm, less "highly evolved" 4-stroke engine. When I say "less highly evolved", I mean that in context of "power produce per cubic inch" or in this case, CC or Liter.
If you do a simple calculation, it shows us just how dominant the Yamaha 4-stroke engines are compared to any other 4-stroke presently produced by any other snowmobile engine manufacturer (normally aspirated).
Yamaha Genesis 1000 .164 HP/CC
Yamaha 1050 .131 HP/CC
Rotax 1200 .112 HP/CC
Based on the calculations above, the Rotax 1200 was clearly designed to be a "lower performance", lower emission, lower RPM better fuel economy snowmobile power plant. The Rotax 1200 was likely designed this way to maintain the superiority of the E-Tech power plants, which BRP is very heavily invested in and cannot risk "out shadowing" by the design of a "superior output", high performance 4-stroke just yet.
To compare the SUPERIORITY of the Yamaha 4-srtoke engines in terms of power and economy...look at the genesis 1050 triple vs the Rotax. Consider the Yamaha is roughly 150cc lower in displacement and it is capable of producing slightly more power than the Rotax 1200 and is at least as fuel efficient as the Rotax 1200, if not better on average.
With this comparison, you can clearly see how good Yamaha Motor Company is at designing and building MOTORS...Yamaha builds the best, most reliable, most powerful fuel efficient engines in the world, for what they were designed to do.
The Genesis 1000 is a "GEM" of an engine for the kind of power this thing makes...it is EXTREMELY fuel efficient!
With all of that...if you want better fuel economy, and it is more imortant than anything else to you...Turk is absolutely correct!

Change the fuel you burn!
I know, easier said than done but consider this...we have all noticed differences in the fuel economy of our cars in general, from one fill-up to the next. No doubt, atmospheric conditions, all things equal have the greatest influence on fuel economy, even with EFI.
I will tell you, a "new variable" was created when the Gov't allowed the addition of Ethanol to motor fuel. Most people never noticed how much ther annual fuel cost increased when these laws went into effect.
Alcohol in general, has to a varing degree based upon what type of alcohol we're considering, roughly half the thermo energy in BTUs vs pure gasoline.
What does this mean? It means it requires twice the volume of alcohol to generate the same level of energy as gasoline!
In essence...YOUR FUEL COSTS WENT UP BECAUSE YOUR FUEL MILEAGE WENT DOWN per pound of fuel burned!
They in effect, based on a ficticious conclusion that stated "we need to reduce CO2 because of the green house effect "lie"...all of that was a simply "a new tax levy" without justification and should never have occured!
You can feed 100 people on the corn required to produce 1 gallon of ethanol and it takes more energy to produce a pound of ethanol than it returns!
Freakin Genius Boys!
Anyway...with the addition of the "making available" E85 fuel at the pump station as well, that opened the door for the "thief gas station owner" to pump or dump, late at night...more alcohol "E85" into the gasoline tanks at their stations, to raise the profit the station owner takes on a gallon of gasoline, which by law is supposed to contain just 10% alcohol...how do YOU know how much alcohol the gas you just pumped actually contains?Now in the states I believe the legislation was passed to allow a greater tax in the form of 15% ethanol in gasoline!
In my area, there are at least 6 stations that sell "no ethanol" regular gasoline...search your area on the net, search ethanol or alcohol free gasoline and you'll find it your area as well.
If you truely want to increase your sleds fuel mileage, FIND fuel which has the lowest percentage alcohol and watch your mileage climb!
This is where a lot of the variation in mileage folks find...actually comes from!

I rode with a GSX 1200 me on 07 Attak GT & doo did use a few 10ths of a US gallon less on 2 fill ups then last leg fill up I used 1/2 gallon less running hard & leading. Doo 1200s vary mpg too & not better than 15mpg in our type of riding & yam 15-20 more HP engine. You should be in the ballpark sounds like all of you should carry extra gas & on edge at 140 miles on fill up for doo 1200 too.
I havent seen anyone suggest changing the fuel mixture with the gauge. My friend's improved mileage when that was done to his under warrenty. As i remember, it allows you to richen or lean fuel below 7000rpms. Possibly this sled needs this done.
mine gets from 14-16, most around here get the same.

Do you have a link to the procedure on how to change the ratio?

A friend of mine developed a hydrogen system for cars. Uses a low amp field to seperate the hydrogen and oxygen and releases it into the intake box. It should work for the sled but, we have a few obstacles to over come. One being the oustside temp will freeze the water supply. He thinks we can add about 20% alcohol to stop the freezing. The other problem it the electrollite isn't goood for the aluminun. Need to find a way to stop any liquid from getting to the throttle body. It's a little more work then I have time for now so it's going to have to wait. I addition he sold all his stuff to an invester and doesn't have the units to play with anymore. He is developing a system for home heating and that has his time tied up. So the brains aren't on my team for a while.

There are other issues as well. So far, it take more electricity to generate the hydrogen than the hydrogen produces and there is some chemical reaction that goes on inside standard gas engines when using hydrogen for long periods of time that weakens some of the metals involved.
It would be nice though, we could call the first sled, the Hindenburg XTX. I'm sure nothing will go wrong.

He has the amps pretty low. It doesn't take much hyrdogen. Just enough to give a full burn
