Ok before I start getting crap for being a newbie and asking a Polaris question. I own a yami and it's all I ever owned. I now have an 98' SRX which is sweet. Well anyways My dads Polaris XLT special 95' or 96' won't start. When he bought it started right away and when we got it back to the house it fired right up now it's two months later and we went out to fire them up and his won't start. Now it was cold the night before 0 degrees so he’s’ thinking that was why. We changed plugs and nothing. The guy he bought from was a mechanic and cleaned the carbs out every year. Do you guys think it could possible moisture in the heads? He put dry gas in but I doubt it ran through yet. Any suggestions?
Thanks Josh
:yam:
 

First thing to do is to read the plugs (fuel) and check for spark.
 
WOW you realllly opened yourself up for some serious clown'n around. But seriously if you have spark, and the plugs aren't soaking wet, put some gas/oil mix down the sparkplug holes. then give it A try. It might take a couple of tries to get the pump primed. Also look for the fuel shutoff valve, it my be closed. If that don't work ya know I just gotta say it, Sell that piece of #$%&* and get a true blue. Just kidding hope ya get it going!
 
Those sleds are known to foul out plugs..sure there not wet???? Brent
 
as you know , you only need three things for a start , gas, spark and compression , since you just had it running a few mo. ago , i would say your safe on the compression, take a nail and push it up in the plug cap , hold on to it and have your dad pull the rope ...youll know real fast if you have spark , if you have spark then its either flooded , fouled plugs , or no fuel , its not recommended but try a few squirts of stating fluid , if the plugs are ok it should fire right up ......if that doenst work ...BUY A YAMMI DAD !!!!!
 
we have have an XLT in our group and he has to shut the gas off every time he is done riding it cuz his sled will flood. We have changed needles and seats 3-4 times but it seems to still flood. Try takeing the pipe off see if you have any gas in it. Then put back on hold carbs wide open and try to start. It should fire that is what we had to do when we found out that it floods.

WARNING if you pour gas down the plugs, make sure the brake is on, and the sled is pointed out the door. You will have no real throttle control over it if you get to much gas in the cylinders. Don't ask how or why I know, just take my word for it. Maxdlx ps some low grade either will help to, if shot in the air box in small amounts.
 
I know why he knows...LMAO! :WayCool: Brent

High bidder gets all the dirt...... :rockon:
 
My wife has a 95 XLT Special. I need to prime the pump in the fall. I like to use premixed gas and pour a little in the cylinders. The pre mix is safe in case you need to try a couple of times. I like my Yammi but I will say that that sled is a nice machine. It's a comfortable ride and her sled is as reliable as any I've ever seen. The other advantage is the Mrs loves it! I couldn't talk her into a new one if my life depended on it. That means I get the new one!
 
There should be a drain at the front and bottom of each cyclinder, pull out the plugs and see if any gas comes out. If so drain all three, let it set for 20 minutes and pull she should go then. We had a Polaris with the same thing the carbs would flood the cylinder after it was shut off, damn reeds never held shut. If this is the problem he'll have to shut the gas off every time like it was stated above.
 
Ok

OK heres the deal. Dad came home and the sled fired right up then stalled out. Then I had to pull my arse off to get it started but wouldn't idle. So we had to keep the gas on it. We blew it out but it wouldn't go over 20mph. So I pulled the plugs the middle one was dry the other two wet and they where cold. So now the problem is only the middle one is firing. Any ideas? I couldn't get it started after that I switched the plugs out. It pops but doesn't turn over.

Thanks Josh

Also Mine started on three pulls. Gotta love yami's
 
yank the carbs off and give them a good cleaning sounds like you have gunk in the carbs
 
no need to worry. its not gonna start, might as well give up now.lol. i would say it is flooded. my buddie had the same problem if he didnt shut of gas if left for a while. youll get it going and have at least one ride on it before it dies. lol, lol. had to say it, you left it open... all the best..
 
Listen to what Kinger is telling you. With the XLT, if it is stored with the rear end raised and the gas left on, it will fill the crankcase full of gas. It needs to be drained. This is very common with the XLT's. They also have a high failure rate on the crank shaft, probably due to gas eating up the crankcase seals.
 
Yeah the crankcase is most likely full of gas. That motor is a POS. Tell your dad to get rid of the sled before it causes he and his wallet major pain. I have a 95 XCR (Same motor, bigger carbs), I had the same problem you had, mine wouldnt even sputter when I sprayed starting fluid in it. I pulled the 3 plugs down belwo, put them back in and it fired first pull.

If the sled has electric start, its kind of a pain to get the PTO side plug out and back in. With a decent extension and a flex socket you should be able to get it, just keep a magnet on hand. When you reinstall it, put some grease on the head of the bolt so it sticks in the socket. I also had to pull my manifold off to get down in there.

I am so glad this Poo is my beater sled, and I have the SX..
 
leave the middle spark plug in, and pull the side cylinders spark plugs, try to get it running with just the middle poping. Should clear out the side cylinders, seeing you won't be pumping any gas with the plugs out. had that happen before, and this worked.
 
I agree, those engines are prone to problems, but if you put pipes on the thing and can somehow avoid blowing it up, you can make those things move. I had a 96 XCR which was stock, and my brother has a 95 with SLP triple pipes, clutched, SLP airbox and flatslide TMX carbs. That thing is a rocket, but does like to blow pistons. Hasn't had a problem with the crank, yet and is trying to avoid further piston failure by running straight premix fuel and eliminating the oil pump.

I also had the problem where the sled would flood and you'd have to empty the crankcase. Kind of a hassle, but it makes it run again at least!
