JUST GOT BACK FROM MICH TODAY.I HAVE A F7 SNO-PRO GREAT SLED LOTS OF POWER.WAS BREAKING THE SLED IN BY THE BOOK AND HAD AROUND 50 MILES ON IT WHEN IT DIED OUT.I WAS DRIVING AROUND 50 TO 65 MPH FOR A LITTLE BIT THEN THE SLED JUST DIED BUT THE MOTOR DIED BY MAKING A WEEZING NOISE LIKE I SPUN A BEARING OR SOMETHING LIKE THAT, IT DID THIS TWICE , THEN IT TOOK ME SEVERAL TIMES TO GET IT STARTED. AFTER THE SECOND TIME IT RUNS FINE NOW AND I PROCEEDED TO GET 120 MILES ON IT.HAS THIS HAPPENED TO ANYBODYS SLED YET. OH YEA AND MY GAS TANK WAS FULL. THANKS LEO

Scorred piston I bet, better take it in, do you have all the updates? Its a long LIST.

I still believe, no proof(well recall good enough), the smart valves, need more education :lol:

The sound was the fuel pump running out of fuel...the valve stuck, then unstuck and on your way...I would do something about the valve or get the new one soon, before you go out again.

 

[switta]

i put a reply on another post asking what does this valve do and got no answer! does anyone know how it works

 

[switta]

only thing drilling a small hole in it is going to do is let the valve relese after the pump stops sucking fuel after the sled has gone lean and died! damage has been done/ drilling the hole will not save your engine!!! it will just relese the valve once the engine has died!!!

 

[ods dan]

actually, the hole will help not let the valve get stuck to begin with...so it will help prevent the close off...but not completely eliminate the valves complete use...just a little bleed off.

 

[switta]

ya that makes sence. but what is it there for??

 

[ods dan]

oh, for real...its so if the tank is low, then you go up a hill it will draw from the rear valve, down a hill, from the front...so it won't suck air...I think another big deal, is not having a return line to the gas tank...that is why I think some of these problems started with.. to eliminate that , it causes a full time fuel pressure, with no relief??

Mine made the same noise when it died, It did start again but I knew it was hurting, Turned out that I got a new piston and cylinder out of the deal, Just to be sure remove the Y-Pipe and take a peak to see if the piston is scored.
Let us know

Thanks

 

[switta]

THANKYOU ? geese hope i dident upset you with that!!!! thats all i wanted to know two days ago . not sure what you ment by the comment .......o for real!!!

 

[ods dan]

no, I meant "what they are there for, for real" dealing with the fuel system..

 

[switta]

ok i just wasent sure :lol: . i do like your comment on a return line ? i wonder why they dont do that like a fuel system on a automobile? iv'e never heard of a auto needing a new smart valve :lol: :lol:

 

[ods dan]

they did have a return, til this sled??? unless at the pump, there is a bleed??.

 

[switta]

ya :lol: :lol: :lol: :lol:

 

[skydog]

Guys a few more days and we all will have the new one from are dealers!! And this will be wayyyyyy in the past!

Skydog :lol:

 

[switta]

ya let's hope so but ya know i would give up my new smart valve for some SNOOOOOOOOOOWWWWWW !!!!! it would get me off this dam computer

 

[lerod]

hey guys thanks for the info, going out tommorrow to put some more miles on , I'll take the y pipe off to check the piston.Talk to you tommorrow night , once again thanks. leo

Dan, my dealer does not have new one in yet. I drilled hole in second smart valve. Is there a fuel filter in the line somewhere, or was that the reason for the screen on the smart valves? Will I be sucking any crap in through the small hole I drilled in the back.

 

[ods dan]

did you drill under the filter...or outside..back
I would of popped the filter off and did it under there.

 

[f7firecat]

Dan, I drilled through the oppisite side of the screen side, through the back and under the screen. Black plastic about half way out the radius, I did not drill through the screen. When the 1/8 hole was made the valve itself popped out as it was stuck shut.
