Water sits on the bottom of the tank always. If you tilt the sled so the water is collected in the front corner of the tank, you can just siphon out a small amount instead of the whole tank! Good luck! Love the videos!

Hell yeah that thing sounds good 👌🏼 my sled blew up today crank is destroyed

Reeds. So when the reeds fail the frequency will push back up through the intake ports and back through the carbs. I think its called the helmholtz frequency. Its the reason everyone tried to make those boost bottles that didn't work. Its why reeds are super important on any two stroke.

There have been a handful of 440s that impressed me glad you have on that rips. I knew from my m.x. backround that reeds are always worth spending some dough on might fix it might not. Anyway she's sounds great so let give her the onions and let her eat.

Great video as always I almost would check the head gaskets what starts to warm up I had a sled that did the same thing I turned out to be the gaskets between the head gasket and a clutch gasket or possibly bad crank but you definitely must will the more than I do how to next video look forward to seeing it

I have a ska 440 and I had to replace all the gas lines including the 1in the tank make sure that you use clean line a you get it from you dealer. By using the clear lines you can see the air bubbles in the hose good luck it fixed mine

Fuel pickup line in the tank, re-sync carbs and start from scratch there. Possibly bad fuel line other then tank? Other than that maybe a ground wire? When you first get on it leaving your house the tail light is flickering some bad, that makes me feel like its electrical. Just some ideas, i know how easy it is to overlook something simple when you've been wrenching on the same sled for so long! Sold the XLT 600 and Ultra 680 by the way, two old triples that went for a good amount. Glad to see that people still like the wedges even in New Brunswick!

Water=KABOOM! BE careful, remove tank rinse completely flush lines, change plugs, report back, good luck nice sled!!!! I have a 94 440 xcr I'm working on.

Love the videos man. I road with my cousin that had one the quick as hell in the trails . Hope u figure it out. Check the safety switch

one of best sled ever made

Great video

I think it might be the coils on your stator that make the charge to run your CDI breaking down when they get hot. I have had that happen many times in the past. It could also be a break in one of the wires from the Stator to the CDI but not as likely. If it is the coils breaking down, it will still show spark when you pull the plugs because the pulse coil will make enough juice to make them spark when you pull it over, but not enough to run it at higher rpm. It is easy to be fooled by it because it will show good spark.

I had this problem once and it was the little tangs that you can bend in your fuel bowl let your float set up a little higher it’s just running itself out a fuel. Happened to me on a quad and maybe that’s it? Mine acted the exact same way. In the manual there was even a diagram with a sea level chart so you could use it as a template when you bend them out

What do your plugs look like after a pull when it starts breaking up

I have a 1997 440 one of the purple ones It does the same thing constantly it was water I actually had the same problem most of the day The old Polaris gas tanks always gave me a problem with condensation

I can tell just by listening that the sled isnt shifting out all the way. Either clutching/jetting/valves dirty or a combination of all

Did you check you fuel pickup in the tank? My friends sled had a crack in the line that let air in from time to time and revealed itself on long pulls and hills.

i use seafoam it seams to work well also try replacing the stator and coil check the tps have a good one

Stator? I’ve seen them act pretty weird when stator is going out. Or sucking air somewhere?

That sounds nice

Its def fuel related, filter,pump,pulse line,the line inside the tank,carb vents, etc

She sounds amazing.. but sometimes not all there when u put it to the bar.. reeds or ves valves? How's the 700? I can't wait to see it back up and running again.

Those r nice with 1999 xc 700 motor in it handle nice

those 440 xcr's are very reliable and quick.

I’m sure you have already checked it but a dirty fuel filter caused similar issues on my xc440

i had same problem with my 1999 500 xc ended up being wire broke in the stator

1998 xcr 440 best sled ever in wedge body

I have an identical problem with my iqr it was the needle and seat

One drop of moisture will plug the vent line and give same result! Try to open the gas cap when it's acting up and you'll know for sure! Hope that helps!

Without the airbox your jetting and needle position will be way off. It will lose quite a bit of power that way because it sucks warm air from under the hood. You could adjust the carbs to run like that but your leaving HP on the table. I would rebuild the fuel pump, replace the reed petals, install new carb boots rebuild the carbs (set float level) and find the proper airbox for that sled. I would then do plug chops at full throttle and at half throttle if you plugs are black lower your needles at full throttle if your plugs are black install a smaller main jet. 1/4 throttle is adjusted with the screws on the carb and they both need to be set the same or carbs will not be synced use a small drill bit to set the slides so they open at the same time when your at idle .

my bad saw it off but then back on at 12:53 must have missed that, those XCR 440 were one of the the best trail sleds you could get back then. I think that was the first engine Polaris put VES on in 1998. I had one, had to rejet every time the temp changed or it didn't run perfect. I ran the vent lines into the airbox, it made jetting easier. If you like to tinker with jetting and clutching they are fun.

@@AKproXR check compression but. my 1st thought with these symptoms is check your fuel pressure. Pumps are cheap. If you have the hoses off the carbs, gas should spray out at least 3 inches when you pull the engine over. If it just trickles out get a new pump. Bad compression can also cause this since they work off vacuum on the lower end. Did you check the carb fuel intake screens. Did you check your gas tank fuel filter. Those may be clogged. Kinked vacuum or fuel lines. Old cracked vacuum lines. Just some of the more common things I've seen on these sleds.
