fuel mileage/overheating

[duamy]

snowchecked 12 pro 800 155 , live in michigan which if you live in the center of the state this is now a no snow zone, went to grayling last saturday on lets say minimal snow in most areas

went up to test and run first tank through machine

i am scared (after reading all the threads out there) about the overheating problems i ran all over the board but consistent 125 to 175 without scratchers down , crappy snow on trail hotter, ran in snow 130s, i did put about a .030 plastic on inside of snow flap instead of buying new one, i will test without when we get better conditions.

i also used 16 to 20oz of oil i put on 62 miles old school guage reads 3/8 left in fuel tank , i will see how many gallons later this week

ASKING YOUR MILEAGE AND OIL CONSUMPTION
i did baby it for the most part but did open her up on short spurts, how couldnt you?!!
front end is awesome over bumps and power is impressive

here in MN and still haven't moved it more than 6 feet (onto the trailer).

Were you on a lake or low-snow trail?

 

[Tree Boss]

My Pro doesn't use a lot of oil but then again it's been 6+ weeks since I rode it. Scratchers must be down unless in deep snow, that's just the way it is. The second you unload the sled you put the scrathers down til you get in deep enough snow that it can keep the sled lubbed which is 6-10 inches from my experience.

I think your jumpin the gun brother.

Im in MI as well and im pretty sure a trail sled would over heat let alone a mountain sled. I ride a 153 M1000 with a 2.25 PC track on it and im not unloading her untill i see at least 3 feet on the ground....

Your going to need an intercooler with the winter here

 

[hiwayman]

I've got 900 miles on my 011 Assault RMK. trail riding I have to run scratchers down to keep temps under 150. Off trail ( logging roads in MN. MTN.s in WY.) temps 125 with no scratchers. mileage is average of 12 mpg. Oil use is so little it's scary So far no piston scuffing on exhaust side.Had Dealer turn pump up last spring and I haven't ridden since.

 

[AndrettiDog]

So why don't you just run it with the scratchers down like all us westerners do? It may not be conventional in your area, but mountain sleds have evolved to no longer use front coolers.

 

[sleddin pete]

Put the scratcher's down,that's the first thing i do after backing it off the trailer.Your sled and Hifax will thank you.

Just bought a 2012 800 pro 155. Have 140 miles on it so far. Ran about 155 degrees with scratchers up. Put them down and get 125-135. Bottom line run scratchers until you get to 5 inches of powder or more.

There has been a lot of discussion about the heating issues... snow flap, scratchers etc. Keep in mind, if this was even close to being a normal snow season out West, you would not see this much discussion. I have 300 miles on my PRO and on the rare good snow days, there is no heating issue.
Just saying..........

okay everyone, going riding again, im putting scratchers down all day, will report back, my question is i put 20oz of oil in, cannot remember how full it was but i cannot get anymore in so i used at max 20oz. just put 7.7 gallons in for around 8miles per gallon. I hope it gets better as this was a break in ride. My minimal snow was 6 to 8 inches with crappy trails.
we ride pipelines etc. so alot of riding on grasses .

my 07 switchback 600 did no better on fuel except one time when i pulled 9.5 when i stayed on the trail, which we try to avoid(rode with different group that day}

get sick of the doo guys telling me 15mpg
also not happy of less oil use then the etecs
oil is cheap, motors are not

just got back from south boardman, maybe 10 inches of solid snow not les.
10 would be max rode some trail,seasonal roads and power/gas lines.
i rode with scratchers down 90 percent of time, im happy to say that overheating is not an issue on this sled with conditions i normally wouldnt ride in.
another slightly positive note, fuel mileage at 88 mile top off was up to 9mpg versus 8.05 at the 62mile top off
i would like to see 10 but i need to learn how to ride it as i dont need to pin it like my old 600 switchback , that is just a fact , she rips
when it hooks up its a arm jerker
i will report back on fuel mileage, i did mix oil again at the 62 mile top off but not at the 88 mile top off, she was burning a little rich

got 7 mpg yesterday. who's counting tho?

towed a ski-doo out today on low snow conditions, and a lot of iced. scratchers down and never went over 165. id say that sums up this overheating discusssion. tho i shouldn't have to worry anyway, it's snowingggggg!

 

[tek9tim]

I had to always run my scratchers on my xp summit in that part of Michigan last winter, except for the 1 day when there was about a foot and a half of new. You're spot on for what's needed riding a mountain sled in MI.

 

[Skeld]

Good lord those fuel mileage numbers sound bleak, but I'm encouraged by your lack of overheating issues. Very little snow here as well so far. Going riding next weekend and I doubt there will be more than a foot to a foot and a half.

 

[forreboy]

fuel

Gets 5 mpg on my pro rmk 800 -12, think it's way too much...
My M8 -11 last year used alot less fuel with more power

You think 5 MPG is too much?

 

[Jaynelson]

MPG LOL are you guys serious?

 

[Oregonsledder]

I have around 300 miles on my 12 PRO, I get closer to 12 MPG, but as with all sleds, it depends on how deep the snow is and how hard I'm pushing it.

 

[forreboy]

You think 5 MPG is too much?

Yes I think it's too much.
As we say in Sweden, we are wasting it for the crows.
That amount of fuel should be enough for 200hp on a twostroke

 

[Skeld]

Ok, I'm with you now and I agree. Unless in heavy snow all the time then you can throw it all out the window. BC smartass, I understand MPG isn't much use to you in deep snow all the time but in this case the OP seems to be riding on very little snow and if the sled only gets 7 MPG when I would expect it to get 12 or more in those conditions, that doesn't seem like a good sign for when you actually get the thing under a load.
