Seeing the 700 Twin only has 1 34mm carb, it must be really good on fuel. Is it, how many miles on a tank. The new Grizz has a 42mm and the Quest has a 42 I think too. They seem to burn alot more fuel then the 500's. Acutally my 600 Grizzly is about the same as a 500SP. They are not good compared to other 500's.
Just wondering the HO SP has a 40mm carb and the 700 Twin has 1 34mm. It should be alot better on fuel then the 500 right? Or maybe i'm wrong but i'm tired of having to carry 5 gallons of gas on my rides.
Anyone one know.
Thanks

Automatic ATVs typically burn more full. The average RPM is higher because of the clutching design. I don't think the 700 will burn any less fuel than the 500's, probably more due to the weight and twin cylinders.

 

What has to be understood is that Polaris could've used two 34mm carbs to feed the two cylinders, but since they fire alternately, the 1 carb would feed both, and it just makes the design so much more simple. As far as fuel consumption goes, I don't have any idea. I had a Grizzly 600, and a sp500, and the Polaris seemed to be fairly better on fuel than the grizzly. Some of this could've been attributed to the high rpm's that the grizzly turned at slow cruising speeds, along with more displacement to feed fuel to.

why do others have two carbs, do they fire togather?

 

jimcb,

No, on the Prairie the power strokes are 90 degress apart. On the Polaris the power strokes are 180 degrees apart. Thus there is actually more time for the carb to recover so they only need one carb. The Banshee operates on the same principle (except that it's a two stroke). They have kits for you to replace the two carbs with one.

One big gripe I have about all of these machines that have EBS, is that the throttle must be left on to continue forward momentum. Therefore you waste gas when if you didn't have an EBS machine you could coast a lot more. I got a chance to take a short ride on the SP 700 recently and only used the brakes when shifting in and out of park. The EBS on that machine is so strong that I would remove it entirely unless I was riding in VERY hilly country.

I don't have mpg numbers yet , but compared to my scrambler {500HO} the 700 is useing more fuel.

I thought the same thing about the EBS after my first ride. Now that I'm used to it, I like it , even on flat ground. But like you said, the drag is killing the gas mileage. I can't wait to actually get it on some big hills!

The 02 SP500 H.O will get about 23 MPG rideing a mix of trails and dirt roads with the emphasis on roads. Rideing my sp700 side by side on the same trails and road, the sp700 got about 14 MPG. A LOT WORSE than the sp 500. Rideing just about all trails my sp700 got about 11 MPG. Plus the sp500 holds a half gallon more fuel. I also checked the sp700 riding all dirt roads and got about 18 MPG. All these fuel mileage checks were done starting out with full tanks with the odometer set at 00.0 and than re-fueling at a gas station just like checking your car or truck. Don't want anyone out there to think I might be pouring it out of a can and guessing. If you ever think of selling your fuel packs, I might be interested. We never got a chance to check the mileage on the sp500 H.O rideing all roads or all trails, but I already know what that outcome will be. [img]i/expressions/face-icon-small-sad.gif[/img]
