Hi guys. I bought a 2008 F1000 LXR that sat for a few years. I syphoned what I could out of the tank and replaced with new gas. Added a bit of isopropyl and put a bit of gas in the cylinders. She fired up and ran. Had the track up in the air. Throttle response was good. Ran until she started to get a bit hot. (like 5 minutes) Shut it off and it has no interest in starting. I would think that would be enough time running to get the old gas through the system and get the new gas and isopropyl in there. Am I wrong? Any ideas? Thanks in advance.

Only two things to check. Fuel and spark. Check to see if getting spark. Check for gas by pulling line off throttle body and try to start and see if fuel comes out. If it does you know it's getting fuel. If not, check fuse for pump. If good, old gas may have deteriorated fuel pickups in tank and plugged pump inlet. It's likely but not 110% sure as it ran for 5 minutes.

Thanks 660catman. I'll be starting to look into this next week. I appreciate your input. I'm just baffled at how it can run great when I put a little gas in the cylinders and pull it over.....then I shut it off and it won't start back up. I guess I don't understand how it keeps running well (keeps getting gas) once I start it by putting a little gas in the cylinders if the fuel pickups or pump inlet are clogged or deteriorated. Struggling with that. I guess when I pull the gas line off and pull it over I'll find out if its still getting gas.

Are you saying it only starts once you feed the cylinders gas? I thought you just did that once and now it doesn’t go.

I started it the first time by putting gas in the cylinders. It ran for about 5 minutes until I shut it off. I tried starting it again and it wouldn't start. I replaced plugs and it still wouldn't start. That's where I started this chat. Gonna get back at it this week now that I/m back in town. Thanks in advance.

OK...worked on the sled last night. Had spark at cylinders.....put a bit of fuel in each. started up and ran. Shut it off and it restarted over and over. I'm guessing I have finally cleared up whatever old gas deposits were ailing me. :) Thanks for your help 660 Catman....even though it turned out to be an easy fix this time. It's appreciated.

No problem, now you need to go on a long run if you got snow yet!

Hi guys. My problem is back again. Ran the sled a month ago for about 50 miles. Ran great. Been sitting in the trailer for a month (no snow) now it won't start again. First real pull it will give a quick sputter. Then nothing at all after that. Pull the plugs and they are wet. Lay the plugs on the cylinder heads and they have spark. What the hell is up? This is driving me nuts. (See copy of my original post below for background on this annoying problem) We finally have some snow and I can't ride. Grrrrrr

Have you tried pulling with the throttle open just a smidge? I know on my F10 it will usually start right about in 2 or 3 pulls, but, if it does that little sputter start then I have more difficulty starting it, but if I crack the throttle just a tiny bit that will usually do the trick.

I have tried that before. Seems to help if was just shut down for like 10 minutes.....but doesn't seem to help cold starting. I literally pulled all the plugs.....watched them have great spark. Put a bit of fuel in each cylinder, pull it over.....and absolutely nothing. I'm starting to yearn for the old days.....Newer electronics suck when they don't work right.:mad:

i guess at this point i would check the compression if you have not done so already. If it is low it can make any sled difficult to start.

And here I thought we had it. I’m stumped as much as anyone. I agree, get a compression reading and we can go from there.

So I ended up taking to the only dealer anywhere near me. (Livingston's....biggest dealer in new England) They took a bit to get to it but seem to have solved the problem. I spoke with Steve Livingston himself and asked him to explain this series of events. Evidently there was hard white crystalized crap making its way around in the injectors caused from the newer ****ty gas. The crystalized stuff was holding the injectors open too much at start up and flooding the machine instantly. He says he has seen it many times before. He says if you have spark it is either a faulty fuel pump giving too much or too little pressure (check fuel pressure to be sure it's what it should be as 1st step) or the injectors need to be manually cleaned out. He also says he never has had to replace an injector for this issue. Hopefully this helps somebody out there!

Thanks for the effort guys!


Cheers,

Steve

I take it a full fuel system flush was done then? I have never had a fuel related issue in any sled or quad I have or had. I use non ethanol fuel only and treat with Seafoam throughout the season. Storage entails using Sta-bil fuel stabilizer.
I know non ethanol fuel is not everywhere especially in rural locations so storage procedures are really important then.
Hopefully you have this all sorted for next year’s season. Unless you still have good riding conditions.

Sounded like they only did the injectors. He said he never had issues after he cleaned them really good. Time will tell I guess. Steve Livingston sounded totally confident that it was the issue. (He is one of the guys who does the "dealer prep" adjustments at the Old Forge Shoot out every year so I'm trusting he has been through this and is correct. BTW...only charged me $170. Fingers crossed!

Yes, I agree the ethanol **** blended fuel sucks. I have drained all I can out of my sleds and I'm going to run some non ethanol fuel (which I finally found fairly close to me) I have started treating with Seafoam as well during the season and have always stored with Sta-bil and never had any issue. Riding is most likely done for the year here. Hopefully next year I get more riding in!!! Thanks again.

Steve
