We should have asked this a long time ago, but, what size is your KingQuad?

I think the check valve is the most likely culprit, unless there is a pinched hose on the vent line somewhere. If you took the valve itself out of the line to check it, are you sure you put it back in the right direction? I would double check all the hoses before you go and buy a new check valve, they run about $30, more from a dealer.

It's a 750 AXI

I have a manual and put the check vale in the correct way. I will check it again to make sure.

I rode it this weekend and it didn't miss a beat. I also checked the fuel cap to see if it was still letting of pressure and I couldn't hear it this time. Damn this thing is driving me crazy.

Mine also makes a sound when you open the cap. Did it start up when you put the cap back on? Have you checked the relays?

So it died while riding or when standing still at idle?

Yes it started back up. I road it the next day and every time I stopped I releaved the pressure and it ran good.

It dies when i'm running. It will run good and then just die like you turned off the key. I was wondering if the fuel shut off gets hot and shuts it off?

Thanks for the help.

Well I had the chance to take the Quad out for a ride. 50 miles into the ride it did it again. This time I checked to see if the fuel pump was running. I could hear it. then I tapped on the fuel shut off to see if that helped. It' didn't. Then I took off the gas cap and I could hear it releave some pressure. My wifes quad would not make a sound when I took the cap off her's. Could that be my problem? A clogged check valve. I blew through it when I had it apart and it would let air pass through it. Damn this is pissing me off.

I think that should do the trick, please let us know how it goes.

Will do.

I have some business to take care of for the next couple of weeks then I will get a chance to get out and see how she runs.

Ok I pulled the fuel tank yesterday and found some water, oil, dirt, and a few small pieces of paper .

The only filter was on bottom of the fuel pump. I cleaned it out as best I could and put everything back together. I guess I will try it again and see what happens. If I do have the problems I will do as you suggested. Thanks for the help.

The only filter that I can find on the parts breakdown is a screen on the fuel pump. I just need to find the time and tear the fuel tank out.

Thanks for the suggestions. I always use 92 octane gas from a clean container. I Snowmobile during the winter and quad during the summer. They get used a lot.

I was planing on pulling the tank and checking out the fuel pump. I will look at the fuel when I drain it. I can't remember if the fuel pump was running or not when it would stall. I have never ran it under 3/4 of a tank and it would still act up. Is there a fuel filter to look at? Also is there any way to check out the fuel pump when I have it removed? Thanks for the help Guys.

Hello,

First time poster. What a great site.

My question is: My 08 King Quad keeps stalling on me. When it stalls I can wait a few minutes and it will start up and ride for a 1/4 mile then stalls again. Wait a few minuets and it will run a 1/4 mile then stall. I took off the air cleaner and it didn't make any difference. if I let it sit for a few hours it will run great. It has 1100 miles on it. This weekend we went for a 50 mile ride and it ran great untill the last few miles. Then it started to stall again. It's driving me crazy. For the record I know nothin about these quads. Any Idea what is wrong with it? It seams that it runs better with a full tank of gas. Thanks for any Info.
