My sled has been sitting for the summer I put stabil in the gas before I stored it for the off season, went to go start it half way through summer, wouldnt start. Second time I tried, I pulled forever and it finally started. Just brought it home, had the same troubles again...Duno why this wud happen seeing i just had started it few days ago. any suggestions ? bad gas? dirty carbs? coil?

Thanks any suggestion greatly appreciated.

It could be any of those things you mentioned.

Are the plugs soaked with gas when your trying to start it or are they dry?

It may just be from sitting and old gas.

Or maybe your carbs need to be cleaned.

I pulled the plugs out twice and wiped them down, they were soaked in gas yes.. after the 3rd time doin so, it finally started.. i pulled it over without any plugs in, put them back in, then it went after the 5th pull.. i'm goin to go over today and see if it will start after sitting over nite, doubt if it will.. :crazy:

Thanks

sounds like dirty carbs or bad gas (doesn't ignite ) next time you pull the plugs also check the spark by putting the plugs in the caps and laying them on something metal on your sled then turning your sled over and checking for spark if there is spark then drain all your fuel (even with stabilizar fuel will still go bad just not as quick) then clean your carbs . :bash:

Sounds like the crankcase might be full of fuel to me. That can be caused by frequently starting the motor and shutting it off without thoroughly warming it up or several other problems.

Pull the plugs and find somebody to pull the sled through a few times while you hold the sled WAY over on it's side - so it's like at a 90 degree angle to the ground, otherwise this won't work.

If you put the plugs back in, and they fuel soak on the first or second pull when you try to start it again, repeat the above exercise. Plugs shouldn't fuel soak unless the choke is on.

Okay, yesterday it started up with less effort.. when the sled is running it seems to run and idle just fine. and after stopping it for a while, it starts rite back up again... . there has to be a spark, it starts everytime. unless the spark isn't constant. i duno. first thing i'm goin to do is check the carbs. if that doesn't solve it then i duno.. the tank is full too, thats almost 12 gallons of gas, and if its not bad, thats a waste. duno what to do..

lol thanks.

:unsure:

Are you storing the sled with the track WAY off the ground, with the front end low? If you are you may be exceeding the angle that the carb floats are comfortable working at. If they aren't working right, that will flood the engine big time in a matter of minutes. That's why the fuel shut off is there. It must be used if the back of the sled is more than just a couple of inches off the ground.

Did you try new plugs its the easys thing to change 1st,drain the fuel & put in your truck or car .I just drained two of my sleds with new sifen it woks great,the old gas gets dilluted in your car.In warm weather your going to run rich , it can foul plugs, I try not to mess with mine till it cools down.

ya, you need to wait till it's cold and snow on the ground and take it for a run. It may run fine once you put a few miles on.

Yeah guys, the sled was stored off the ground with the sled jack, i was told to keep the rear off the ground, so i bet thats what happened, the floats got messed up.. will they be alright once it sits level and once its been running a few times? i have more probs i just realized last nite, the rear suspension is sittin ### end on the ground, i think one of my shocks is gone, anyone know what wud cuz it to go all of a sudden? maybe having the rear suspended all summer?

Thanks alot.. SWRules

your floats will be fine they hardly ever go bad. you do have the gas turned on right? try putting fresh gas in it. mike

I have been storing my sleds with the rearend and track about 15 inches off the floor on a lift and start it up once a week or so.I have been doing this for many many years and have never had the floats stick.Think of some of the acute angles you a put the carbs in when climbing long steep hills and up steep ramps on your truck. I also have never had gas go bad in just a few months especially when you put some type of stabilizer in the tank.Hope you find out what the problem is, Im sure its probably nothing major.Like others said, if you start it up, let it run to warm up alittle bit.Just the other day I had my 800 out around the yeard after it sat in the trailer for months and no problems.Good Luck!

Never had problems with my 04 supersport, I love the fan. Its been great. Last winter I took it to Artic man here in Alaska. I have a Snowstuff silencer new pro-x plastic skis. Riser, fox shox. I put in a tach and acouple other do dads. I fan works great here. had it over 10,000Feet at summit lake and it did great, and I Just put in new gears and changed the secondary spring for more top speed. We just got a little snow so I should be able to try it out soon. Old Gearing was 19/39 with 72pitch chain, New gearing for (LAKE ONLY) 22/39 W/74pitch chain....

Getting stoked to try it out. old 19/39 gearing was around 80mph. So well see how the now gears goes.

Oh yeah make sure you fuel line coming into the fuel shutoff valve is not pinched, Polaris runs them too close to the air box and case, could be pinched, hapend to me before dude.. Good luck Bro! Prob be ok once the snow flys man.

Supersportdave...

Starting it and running it without driving it will carbon it up and possibly foul the plugs.

Wait till there's some snow and take it for a rip and get it cleaned out and fluids flowing.

It's hard to trouble shoot this time of year.

Hears some factory gearing for you gear heads out there!!!

550 Supersport 19/29 72p chain p-spring blue/white s-spring red/blue

xc 500 22/40 74p chain p-spring black/green s-spring black/red

xc 600 23/39 74p chain p-spring blue/white s-spring red/blue

xc 700 25/41 76p chain p-spring black/green s-spring black/red

xc 800 24/40 76p chain p-spring black/green s-spring black/red


Hope that helps someone out, took me awhile to dig this stuff up may be a shortcut for you guys! just remember guys if you change you gear ratios you will more than likely need to adjust spring tension to speed up or slow down clutch engagement, depending on what your trying to accomplish... Oh yeah and 90 percent of the time you do not need to go outside OEM applications for clutch springs, helixs, or primary weights because polaris uses them on other applications.

Example: You think you need the latest trendy clutch kit from joe shows sled shop! WRONG. Your dealer has many spring, weight, gear and helixs for 75% less cost.

Example 2: So lets say you have a 500XC Sp and you want more top end, or maybe you want the acceleration of your buddies Pro-X??? If you experiement a little with other sled set ups you may just learn a little and end up with a couple of set ups that are perfect for different conditions. Remember, Polaris sets up our sleds quite conservativly for reliablility issues and for a broad spectrum of terrain features. But you can countour your gearing/clutch set up more for YOUR riding conditions/preferences. Just remember dont go overboard and make adjustments slowly not to over work your drivetrain...

Have fun guys I've got to get back to work. Oh yeah by the way its snowing here in alaska and we are packed up for a Sunday ride.

Peace. :whistling:
