Make sure you have the right plugs in it, I could be 100% wrong and I am completely going of a wierd memory in my head but I want to say that sled took a special plug. I had an uncle with the same sled. Like I said I could be wrong. Hope you get it running right, keep up the great vids!
Had that problem on my Polaris 550 this year. I cut the plug wire back to good clean wire and replaced the boot end and it ran fine after that. I did all the same things you did before that. That ended up being the problem.
Spray carb cleaner behind the clutch while it's running and see if that dead hole fires. If it does, you have a bad pto crankshaft seal. Also check your carb boot and reeds on that pto side. You swapped the pto plug wire to the mag side and it fired, so it's def not a spark or ignition issue. It's a lack of fuel issue, u just need to find out what is causing it. My money is on the crank seal, seen it before on these particular motors. I'm anxious to see if I'm right haha
I had this issue this year on the "new" 2002 polaris 550 classic we got. This is exactly what I did and put a new crank seal in to solve the problem. This was after replacing the reed valves!
Hi Mr. Rhydes & Valhalla Mike, I'm thinking the next step would be to get the ohm meter out. I like to trouble shoot electrical, no grease, gas, or oil to mess with! Ski-doo gives values for the ignition system parts. I would start at ignition coil, it doesn't seem like trigger coil. But you can't assume.... Thanks guys! 12k to go! I enjoy the sled vids and lookin forward to KLR, quad and pit bike stuff!!!!
Did you happen to check the reeds while you had the carbs off? Could have some bent or broken reed pedals on that cylinder. Pto side runs hot due to the clutch heat. Could have an air leak on the pto crank seal. Neither of these issues will show up on a compression test
In the video you have cleaned the carbs but the floats height were not check. If not in the specs it might flood the carbs. Not a bad idea to put new pilot jets. Also did you check the choke adjustment? Proper spark plug gap helps for good ignition. Finally you have changed the MEPM module, but when the engine is replaced (or new crank) it might be some calibration to do with buds software (i.e. timing). The module comes from another sled, so the calibration is not perfectly set for this mxz.
Try the good wire on the bad side and it should hopefully run. If thats the case it's either the coil or the wires and caps. New coil should solve it then.
Anything with DESS & MPEM is a pain in the ass... My newest sled is a 99 MXZ 67OHO....I have the fact super oddball but quick as hell... I'm all for the mullet and you gotta do a video with Poison playing I background.. Thinking time you get your hands on some Harleys as well...
I run my belt 8th inch above seconday. The machine? Did you check the crank seal pto side? Could have a bad crank seal leak if its running just as bad when you sort your ignition/spark issue Guess we will see next season huh. Cheers
Could be plug wires, caps, ignition coil, stator, or bad new computer. I would personally take out the stator and look for burn marks. Happens all the time
Spray break clean lightly on both sides of the motor. If it revs up it’s a crack in the carb boot or you are sucking air through the crank seal and it will make it run like that
id assume bad coil , or something electrical... 120psi is a little low for skidoo usually there closer to 150but its still good enough to run... electrical is always where youll find these sort of issues
Try filling up the gas tank to at least half way. If it runs better its probably the fuel pump or the hose that goes into the tank. Might be sucking air somewhere. Or impulse line for the pump.
Get yourself new plug wires and caps! Also check all the electrical with a multimeter to assure current is flowing properly. It should be simple. You've pretty much narrowed it down to a handful of things. Possibly the stator.
I love snowmobiling but it's a rich man's sport replace the ignition coil if it doesn't work after that take the engine out and rebuild it or just replace the gaskets and seals
New spark plug wires. Check plug gap, if nippel on top of plug is a screw on make sure it's tight, mJe sure theirs nit one stuck in wire boot, possibly faulty plug
Check your stater on it. Or the coil pack. If that Dosent work then check to see if you have a leaking crank seal. Spray carb clear on the back side of the clutch with it idling and if it revs up then you have a bad crank seal.
Could be a blown piston skirt I had a old Polaris fan that blew a mag side piston skirt still had 135 compression but couldn’t pull fuel in due to the piston skirt being blown
Pull the carbs and look at the pistons through intake ports while turning the engine over, could be a broken piston skirt I had the same issue with an old Cat, it would idle but wouldn't hardly pull itself, and it tested 130 on compression test on both sides.
Sounds like your stator behind your recoil is dirty and you definitely have a bad coil pack pull stator out and clean it up and get a coil should help with the problem
Need new plug wires and all the b.s boxes and sparkaltors that go to it lol they all do that shit it's easier to just buy the whole setup with the wires and see if that works. If not atleast you will have a badass new sled when your dome to give away when you reach sub goal
It sounds like you have a spark plug issue like the cabin self maybe it’s the CDI box maybe it’s the whole box change the coil box maybe that is the problem I guarantee you that is it because like you take off one side, it will not start and you take the other side and put it on the one that doesn’t start a fire is up and wants to fire up so to me there is a week single
I had a sea doo with a funked up voltage regulator. Would idle fine but would very intermittently run like it had a rev limiter. I know you changed it but may that one is bad too?
It’s Mpem I know it’s new but I’m sure you both it used and it’s probably got a different timeing then the original one I have the same problem with one I just got had no tether with it so I replaced the box and tether runs just like yours now take it to the dealership have them turn the dess of will run like new that’s why the tach stops working when you let off the throttle
Subscribe. It's free. I'll even give you a high five. I want to hit 100k subscribers this year and give away a snowmobile (or two).
All you got to do is keep up with the videos man that's all your subscribers ask for
@@WarrantZeus1I mean I'd take a free sled for watching UA-cam instead of going to bed
Stator/pickup problem.

Coil pack most likely, not enough spark energy
Jeremy, please post when you guys figure this out; have been following the videos on this sled so NEED to know. Thank you!
start it in the dark with the hood up and see if you have spark jumping anywhere
That and test the coil to the problem cylinder and see if the voltage coming out is the same as the other side
Let's get 3000 Likes for the mullet Boyz 🍻
Doing God's work.
Had that problem on my Polaris 550 this year. I cut the plug wire back to good clean wire and replaced the boot end and it ran fine after that. I did all the same things you did before that. That ended up being the problem.
Clip the wires get some fresh wore on the boots, check the reeds
I had the Same problem with pretty much the same seld it’s the coil for the plug wires. Hope that helps you 😊
i hope theres more videos coming on this thing tho! im too invested now and want to see it running good
Same!
Spray carb cleaner behind the clutch while it's running and see if that dead hole fires. If it does, you have a bad pto crankshaft seal. Also check your carb boot and reeds on that pto side.

i agree with this assesment

Hey Jeremy and Mike only the O.G. guys will know what RIDE MORE is . As i do b been here since day 1 , fellow Vt man here
mikes jeep is looking bad ass
I think ya should do a camping trip middle of summer on the sleds hahah
Did you happen to check the reeds while you had the carbs off? Could have some bent or broken reed pedals on that cylinder. Pto side runs hot due to the clutch heat. Could have an air leak on the pto crank seal. Neither of these issues will show up on a compression test
When Mike said, "should I order a pizza?", after the ramen I almost peed myself.

had the same issue and it was the spark plug boot

Love the videos!! And mike lol switch the carbs
plug caps wire needs to be replaced
Check ur reeds. Otherwise, if sparks good, totally clean those carbs. Disassemble, sonic clean. Make sure float height is set right on both carbs.
Anything with DESS & MPEM is a pain in the ass...
My newest sled is a 99 MXZ 67OHO....I have the fact super oddball but quick as hell...
I'm all for the mullet and you gotta do a video with Poison playing I background..
Thinking time you get your hands on some Harleys as well...
would love some KLR trips, thanks for the video's guys
Spark plug boot (cut back the wire. That’s the most over looked and simplest fixes. Much more common than people think.
I like the Eagle in the background, what's the plans for that?
I run my belt 8th inch above seconday.
The machine? Did you check the crank seal pto side? Could have a bad crank seal leak if its running just as bad when you sort your ignition/spark issue
Guess we will see next season huh.
Cheers
Could be plug wires, caps, ignition coil, stator, or bad new computer. I would personally take out the stator and look for burn marks. Happens all the time
Measure resistance and continuity to ground on the windings without pulling the stator. Usually tells the tale
Nice, usually the videos YT recommends are like 5 years not 5 hours old :P Keep smiling!
Spray break clean lightly on both sides of the motor. If it revs up it’s a crack in the carb boot or you are sucking air through the crank seal and it will make it run like that
Maybey check the wear if there is reed intake valves. Or check for exhaust plugging or obstructions if it was sitting a long while.
Where did you get the kill switch from just curious bc I have 2 mxz’s and they need new ones and I can’t find them anywhere
Hey bro love your video u should make a water skipper out of a old sled or buy a rev and put a 800 engine in it
Get the new spark plug boot . It’s a whole complete thing . Look it up 😊
5.8k views and only 1k likes 🤯 telling me all you didn't like the video or the badass videos they make and put out. Jeez
id assume bad coil , or something electrical... 120psi is a little low for skidoo usually there closer to 150but its still good enough to run... electrical is always where youll find these sort of issues

I believe that would affect both cylinders
@@seanstevens1483 My 2001 lynx 700 did the exact same thing. Only affected the pto side. Dont know why.
4:45 we prefer Canaderp or if you've had a couple wobbly pops it could be pronounced CanaDUH🤣😂
Get yourself new plug wires and caps! Also check all the electrical with a multimeter to assure current is flowing properly. It should be simple. You've pretty much narrowed it down to a handful of things. Possibly the stator.
You guys got a plan out another adventure yeah I'm up here in New Hampshire around Laconia looks like the snowmobile season has ended
im right by you. sleds are parked for the season. bike and 4 wheeler weather now
I love snowmobiling but it's a rich man's sport replace the ignition coil if it doesn't work after that take the engine out and rebuild it or just replace the gaskets and seals
New spark plug wires. Check plug gap, if nippel on top of plug is a screw on make sure it's tight, mJe sure theirs nit one stuck in wire boot, possibly faulty plug

Could be a blown piston skirt I had a old Polaris fan that blew a mag side piston skirt still had 135 compression but couldn’t pull fuel in due to the piston skirt being blown
Had a 2003 skidoo Legend 800 running on one and it was just a plug boot.
I'm going to guess a intermittent stator or voltage regulator
I would OHM out the stator. 2 strokes fire at TDC and BDC. Can swap wires/cylinder to diagnose. Ohm the primary and secondary coil wires
Good sound track!
Take the cap off the spark plug wire and cut the end off a little bit of the plug wire and put the cap back on and see if it works
Had an issue like this on my polaris. Would misfire on the clutch side. Replaced the one and it stopped misfiring.
Pull the carbs and look at the pistons through intake ports while turning the engine over, could be a broken piston skirt I had the same issue with an old Cat, it would idle but wouldn't hardly pull itself, and it tested 130 on compression test on both sides.
I had to clip the ignition wire back & re-thread the plug cap back on the wire.
Beautiful day here in VT!
I like the videos, keep up the good work!
Maybe check the fuel pump, i had that problem on my phazer once, because the fuel pump wasnt primed one one of the carbs.
Take the airbox off and get it running on the one cylinder and spray some starting fluid in the carb on the side thats not lighting off
I heard it the first time you started it, run on one cylinder. You hold that puppy wide open with one cylinder running, not good lol !
Back in the day we would buy a new part nope did not fix it buy another part nope don’t work lol
Looks like the belt should be going higher on the primary clutch.
Probably not grounded good? Maybe the cdi or regulator. Sounds electrical to me.
I have the same problem with my sled
Great video. Idk what could be wrong with it
Crank seal, or air leak is my bet. Check reeds too.
Mike needs a p o box we want to send him some stuff
Carburetors out-of-sync
Try the ski doo ignition module one went out on my ski doo and it had the same problem running on one cylinder
Try getting a new metal case for both of the spark plug’s
How much would it cost to get that shirt
Clip the ends of the wires
Snip the bad cylinder spark plug wire back a bit.
Sounds like your stator behind your recoil is dirty and you definitely have a bad coil pack pull stator out and clean it up and get a coil should help with the problem
Great videos
Mike earned the dislike for the I hate ozzy comment 😂😂 jk keep the great vids comin! Can't wait till sledding season next fall
Need new plug wires and all the b.s boxes and sparkaltors that go to it lol they all do that shit it's easier to just buy the whole setup with the wires and see if that works. If not atleast you will have a badass new sled when your dome to give away when you reach sub goal
Sounds blown to me
Replace your coil. I had the same problem on my 2000 mxz 700, and I worked fine after I replaced the coil.
It sounds like you have a spark plug issue like the cabin self maybe it’s the CDI box maybe it’s the whole box change the coil box maybe that is the problem I guarantee you that is it because like you take off one side, it will not start and you take the other side and put it on the one that doesn’t start a fire is up and wants to fire up so to me there is a week single
I think it’s the fuel pump. Or your magneto.
My cousins did the same thing it ended up just being water in the gas tank
Stator possibly
Could be a bad crank seal on portals side
I had a sea doo with a funked up voltage regulator. Would idle fine but would very intermittently run like it had a rev limiter. I know you changed it but may that one is bad too?
Did you look at the reeds when you had the carbs off?
Definitely ignition coil
It’s Mpem I know it’s new but I’m sure you both it used and it’s probably got a different timeing then the original one I have the same problem with one I just got had no tether with it so I replaced the box and tether runs just like yours now take it to the dealership have them turn the dess of will run like new that’s why the tach stops working when you let off the throttle
Sounds like it’s out on one side
Do a resistance test on the coil
Valhalla mike has clothes without holes? :P
I'm only here to like, share, and subscribe so I can see the mullet! 😅
Been here for years!!

coil pack brother
Your buddy Justin I think his name is has a 98 xc 700 you and/or Mike need that sled, subs will go through the roof guaranteed 👍
Coil is shot or carb isn’t getting fuel to that cylinder
check the air in the tires lately..
Definitely stoked to see some more year-round vids. Looking forward to the minibike and 4-wheeler content. Side note, Ozzy Osbourne is overrated.
Test the coils? Get new wires resistance could be too high
my skidoo rev does that to i got no clue
i had a skidoo like that and the security tether went bad. The sled was super boggy. dealer charged $80 for a new one
crank seals or change the coils
It's that key switch u replaced
needle and seat
Ik this is a very late reply but have you guys replaced the cdi yet.
