I was talkin to a guy Filling his F5 in so vt. He said that Central Vermont Snowmobiles in Rutland told him that with EFI if you run out of gas you could burn up or ruin your motor? Sounds like total B.S. to me but is this possible? Maybe a slim chance?

there is a post on this awhile ago

Thanks Rev I'll look it up.

running an efi sled out of gas,would be similar to clogged jets on carbs,you would be running lean,, yes that can damage the motor,,,

 

[SnoPro28x]

cant u jus avoid this problem and keep yur damn sled with gas in it!? its real simple lol

Hence the reason for the "Smart" (or not so Smart) valves in the fuel tanks on the EFI sleds.

If you ride long enough it is inevitable. Unless you only ride on a race track.

Stay near the gas stations!! That must suck, but may have to be a rule while riding the F7!

 

[mainecat]

Freeze if your doin 15 to 35 mph on the trail you can feel the efi sputtering out of gas. I have done that and shut it down with no problems. BUT if you were WOT on the lake BANG!!!! Too Lean!!!

Thats the most rediculous thing I ever heard. Would you guys use just a little commom sense please. Come on! :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:





F7 owners gotta be the most gulable around. :lol: :lol:

The F7 gets great mileage-If your riding with any other models at all-they will be looking for gas before you.

TOURING ACROSS QUEBEC WITH A AUX. GAS TANK ON THE BACK.GAS RANGE WILL BE OVER 200 MILES.

 

[gocaps]

If you run out of gas the motor stops - how can there be damage? Might be a bear to start, though. Not saying I know, just don't see the damage thing.

One sled here in northern VT that I know of has burned down because of running out of gas. Its not the only sled I've ever heard of burning down because of running our of gas. My buddy had an '00 SRX that he blew 2 pistons in up in Quebec by running it out of gas. The other sleds he was riding with had already run out of fuel, and he was trying to make it to the gas station when he ran out of fuel at normal RPM (sorry I don't know what that was)...but I know it wasn't WOT. Running out of gas leans out the machine....pure and simple....when you have a VERY high compression motor.....running it without adequate lubrication......draw your own conclusion, or just look in your owners manual....

I ran out of gas Thurs. nite on trail beside the hwy. between Wakefield and Bergland w/. 114 miles on . I couldn't believe the mpg was that bad. 8.8 sure glad it has 13 gal tank. Thanks Dean and friend for the help, sorry your Black Saber shut down and the Formula losing a cyl. two miles later though. It was a full moon nite ,thats the only explanation. Red Sabercat F7.........

I concur LOL ridiculous! Give this a little thought people...

 

[madmike]

ok all you doubters why don't you give it some thought ????does anyone know what detonation is??does anyone know the consequences of detonation??maybe you may want to also do some research on cumbustion chamber temps and the problems that can stem from not enough fuel,, before you start ranting on how rediculous this is,,mike :blink:

 

[Guest]

Not to start anything but I think most of us understand combustion. Does not "running out of fuel" mean that there is not no more fuel to burn? Your assertion seems to state that when you run out of fuel you run in a lean state for an extended period of time? The one or two times I have ever ran out of gas it was cough cough dead! Engines will not burn down in the second or two that you run out of gas and lean the mixture. Without fuel to burn there is no heat to melt. Am I ranting now LOL. I think not.

 

[madmike]

i did not say that every time you run out of gas that you can blow your motor, what i am saying is you can hurt your motor by running it out of gas, and further more no two engines are the same, every motor will react differently,so now knowing what you know, do you purposely run your sled out of fuel ,or do you avoid it??simple yes or no will do,and also are you saying or gauranteeing that running out of gas will not damage your motor,,also are you saying that the coughing you are feeling is not having an effect on your motor ,,i'm not trying to start an argument ,it is common sense,, the question was will it hurt the motor is it bs or maybe a little. i'll leave it up to the owner of the sled, will i try run mine out of gas, the answer is no,,but thats what makes this site great everyone has there own opinions,, and i do respect that,have a good one,duke1n

I have run out of gas twice with an EFI. When I heard it starting to go I shut it down. There were no consequences either time except having to swallow my pride and be towed in. For those who feel it would be ridiculous to run out of gas I would have to say that if you ride enough in wild remote country sooner or later it will happen. One time the gas station shown on the map in northern Quebec was not there and a 100 mile run turned into a 180 mile run. Another time a faulty piston resulted in 1/2 the normal range. Would I say that it couldn't hurt the engine? Absolutely not. I do feel the smart valves are designed to shut down as soon as air is introduced so in my experience the engine shut down almost immediately. I also had no problem either time getting the engine to start back up once filled. Maybe I'm just lucky but like the guy said, " I'd rather be lucky than smart any day!"
