That starter is a champ. I honestly can't believe it survived all the abuse. Seriously dude take it easy. More starter burning or endless kickstarts won't make it run if there's other issues like bad spark plugs. This is mechanics 101, you're going to ruin good machines that way
the "knock sensor" i think is more likely an oil pressure switch. Hence why there is oil that is under pressure at that location. Knock sensors just sit in a metal chunk of block sensing pre-detornation knocks. That could be because of bad gas or excessive temperatures causing the gas to ignite at the wrong moment. (remember your coolant was super low, overheat and fuel was detonating wrong and the computer caught all that crap red-handed.)
Over heating is an under statement. It's hard to believe a machine that cost what this machine cost doesn't have an overheating shutdown before it gets so hot it melts plastic.
An overheating shutdown is also a system that can fail. Remember what happened to Apollo 13, the overheating cutoff switch failed to activate during tank testing because it was not rated to operate properly at all possible supply voltages.
It has a temp light, operator is responsable to shut of sled when lights come on, at some point rider needs to use common sense and not destroy his sled.
@@4knanapapa sounds logical but for snomobilers all eyes are on the trail or you go off the trail you go. My Nytro shuts off on it's own when left to sit and idle and overheat on it's own. But it doesn't shut down at the first over heat light when I am riding. When it does come on (and I notice it), I typically slow down and ride off trail a bit in search of loose snow which works fine every time. But during an intense trail ride I can definitely believe that light can be easily overlooked.

Quick note. Knock sensors can’t leak oil. :-). They measure a for a sharp knock throughout the engine block. They are normally a piezoelectric device. More vibration generates a high voltage signal. The computer knows cam and crank position as well as when spark is fired. So a knock signal larger than normal combustion near TDC or before the next spark event indicates which cylinder was knocking. Looks to me you need two sensors. Those engines are some of the best ever. Great power at 10,000 RPM and reliable at the same time. And the sound is incredible! My current RX1 I got for $1k. Wouldn’t start. Owner claimed it had a new solenoid and battery. Got it home and found some carb floats were stuck and filled the crankcase with oil and gas mix. Rebuilt the carbs, changed the oil and bought a new battery. Run like new ever since. Great sled it’s become a keeper. But I would replace it for an Apex like yours!

Hey Joe on that APEX's when you start them up on the display there's a red light that comes on after you start it. When the red light goes out then your good to turn it off or your foul plugs all day long on that machine.
Nevermind I seen you figured that one out already... Good job. Watch Pete over on Redneck and Dirty Hands he's really good with them sleds and explains a lot on why they fail and how to prevent them. Hope it helps
As a general rule, knock sensors are single wire and thread into a hole that does NOT go into any passage but bottoms out somewhere in the side of the blocks water jacket, without contacting coolant, oil or anything else except the block. I believe yours is just above and to the left of the oil pressure sensor looking front to back. Very low coolant can trigger the knock sensor because A) The engine will knock when hot or with bad fuel due to multiple combustions colliding in the cylinder (it's hot) and or B) because the knock sensor is essentially screwed into a hollow drum i.e. the coolant dampens the knock by filling the drum. Naturally a rod knock will trigger the knock sensor as well.
I had an 03 RX1, crazy fast!! Mine was carbed, would’ve rather had FI. Fast but HEAVY. Great for lake runs and packed trails. If you go off trail in any depth, walk away and come back in the spring- haha.
My apex weighs less than a 2024 Polaris xc s4 everyone thinks Yamaha is heavy. But there are new sleds out there that weigh more. But no one mentions them. Just saying.
Always remember on most single wire sensors of any kind. Use the housing as a ground. You should use liquid thread sealant to seal threads not Teflon tape, which will insulate the ground causing issues.
As soon as you put the black old plugs in I said wait for the new plugs. The old plugs were black and shiny. Means excess oil or fuel. My dad was a mechanic and he showed me that if there is fouling, pull the plugs out and turn the engine over. Heat the plugs up and re-install. Start as soon as possible.

You probably figured it out but the knock sensor is between the middle 2 cyl about 5 inches from your oil pressure sensor. Replace it. Put the nose up on a snow bank and pop the coolant cap to burp the system. Don't ride until you clear all the codes. The sled will shut off if it doesn't see oil pressure that is the code 30 you mentioned. You stole the sled, even if #1 is a little low on compression, run the yamaha ring free for a few tanks and you may get lucky. What was that ticking when it was first outside? That is how they are supposed to start, don't crank longer then 20 seconds, swap the plugs immediately. Have fun!
Hey brother, I've noticed in a couple of videos that you're leaving the outboards in the up position on the boats. You should always leave them in the down position in freezing weather. Water will collect in the foot through the exhaust and freeze and bust the foot. Hopefully it's not too late! Just an FYI.
Most people I know that have outboards that keep them in the up position make sure there is no water inside when they store them so if that has been done there shouldn't be a problem
@@186scott It doesn't matter if you drain them. If you leave them up and out in the weather and it rains it goes down the exhaust and collects in the foot where it can then freeze and bust but, to be honest, I don't know that much about boats. I grew up on the largest man-made lake east of the Mississippi, got my first boat when I was 13 and still own one to this day at 60, worked at a marina pumping gas from 13 to 16, drove a marine forklift at a dry dock storge and hauled 35 ft boats around as well as worked on them as a profession for 2 years so, it makes perfect sense to leave an OB or the outdrive of an IO up and take a chance on it freezing rather than put it in the down position and be absolutely sure it doesn't freeze. That's what all my friends do. Your friends are probably smarter than mine. I don't know what I was thinking trying to give some friendly advice to someone and possibly save them some time and money...My Bad! But hey! It'll make great content! 😏
@@ThaFailedMusician not trying to start anything and I am sure like me a few others are surprised by another way of storing them and I do completely understand your way and there are multiple way to skin a cat and I am sure there will be others that agree with you and agree with what I said
You should put the retainer back in your plug socket instead of dropping plugs down into the engine like that. It could alter the plug gap just saying. But great video as always Joe
when you first pulled that sensor due to leak i was thinking that looked like an oil pressure switch, not knock sensor but i don't know much about those sleds. also..... i don't know who makes starters for yamaha but kudos to them for making a stout starter cuz you were giving that starter hell!
Hopefully the snow sets up better. Here it is too fresh and fluffy. If he can find some hard pack next time, he'll definitely lift the skis and fly vs all the track spin we are seeing here. Motor sounds like an angry bee -sweet and powerful.
Dude I'm from south carolina and have never so much as sat on a snow machine and for some reason ur snow machine videos arw my absolute favorite ones to watch.
Ps a old plumber's trick was to put ptfe tape on like you did But put more around the tapering end with grease with heat forms a gasket perfect water oil tight 👌
To really get the antifreeze burped out, raise the front of the sled 45 degrees and continue to add until full. The coolant lines typically go all the way back above the track. These 4 bangers are fast.
Is there a reason you don't use starter fluid? It seems to me that you could rule out spark/fuel issues with a few shots of the stuff. It would save a lot of abuse on the starter. I'm surprised you didn't burn that one up.
I wrote it on the previous video of this machine, if it got that hot like the oil was cooking chances other parts are hit hard too. Like valves cam and Rod and crankshaft and all bearings or oil pump and everything engine-related took a hit. For a reliable machine, you should take the engine apart and check every piece for heat damage. Now you could have a machine that breaks down every time you take it for a spin. There is always a part that fails later on due to extensive overheating, this was a severe overheating. I wouldn't trust that engine .
any yamaha guy is a buddy of mine. my 03 rx1 is still gunning too. it's got about 30k+ miles since it used to be our log hauling machine but the chassis wore out and had recently stuffed everything into a rs vector gt. now she's a cruiser 😊. i love how these machines are all interchangeable its just a lot of work..nonetheless, nice machine bro 👊 happy holidays and you just got a sub frm northwest Alaska 👍
buy up all the yamahas , they are leaving the game after this year. stick that one in the 2vintage museum. shes a collector now. they are fast as anything out there. its a trail beast thou!! have fun with it joe.
Great job getting that beautiful ski up and running. I really was shocked you didn't check the coolant before even firing that thing for the first time. Remember it did overheat lol. Other than that killer deal.
Fantastic work. Bravo for not giving up on it! As hot as the motor got, I'm surprised more sensors were not damaged. Thank you for sharing another great video. Safe travels. Cheers.
Great video, I like you are cutting short the intro to your basic diagnostics, but would like the voice over explaining what and why. I also look at snowmobiles as the biggest waste of money. Paying $7k in 2012 is like 12k today to go play in the snow 2-3x a year? I would rent one instead. Kinda like jet skis, easier to haul than a snowmobile, but i have had three friends rupture tendons and ACL tears trying to get back on them in the water. I will stick to motorcycles and ATV’s
This has been a terrible winter so far in wi for sledding, The grass is barely covered around me and I'm not that far away from Joe's location. Between the high cost of new sleds and declining snow condition its been killing the sport for 50 years.
Snomobiling can be much more than 2 - 3 rides playing in the snow. With hundred to thousands of miles of trails it becomes a destination thing, ice fishing, to a nice restaurant, or an overnight at a hotel etc -a couple of hundred miles per ride at times and a very social thing to do when you all have sleds. I do a yearly three day ride from Manitoba to Minnesota with a group of friends and it's a highlight experience every time. But those Jet skis are more like you are saying, around and around in circles gets boring pretty quick from what I see.
knock sensor will be near the manifold. I can tell how excited you are.. LOL I would want to ride the 1000 too, they are so fun. When you get it going and feel comfortable it will be so rewarding. Check or change all the sensors. More than likely all of them melted. Most are only rated for a certain heat level, they are supposed to fail in the event of overheat. That way you get all these codes and it stops a person from mechanical damage. Fail points are engineered into everything with a gas motor. Your gonna want to put a longer track on it for sure. For the price I would add a long track. Good Score man!!
This thing must've gotten lava hot for all these components to melt like they did. Even the dipstick, which was separate from the engine itself, was goo. Can't wait to see how it ends with this beast, but I wouldn't hold my breath because all of these melted components can't be a good sign for the engine (and subsequently the one low cylinder). I'm hoping there's no damage to the wiring harness because judging by how hot it got, it'd be a miracle if it's still 💯% intact. Good luck in advance!
That starter is a champ. I honestly can't believe it survived all the abuse. Seriously dude take it easy. More starter burning or endless kickstarts won't make it run if there's other issues like bad spark plugs. This is mechanics 101, you're going to ruin good machines that way
Lol I'm not telling him what to do, of course it's his. I'm offering constructive criticism. If you wreck a good machine doing stuff like that, it's hard to make money.
Yamahas are famous for fouling plugs from oil injection settings on cable, got to find that sweet spot, you probably know that right? you set it measuring how much distance between the end of outer cable as you pull out from seating, most are around 1inch, easy fix if too rich, temperamental believe just saying, from a nobody up in maine, ya I’m jealous 🤔, love your content!👍🏻🇺🇸
If you are going to sell it I hope you do very well with it. The sound is fantastic, can't help wondering if that is a YZF1000 engine or similar. What a hassle to get things apart though. Garage costs for repairs must be sky high as I mentioned before. 100mph ? On the snow ? Wow ! Well done that was great to watch, thanks :)
These thing fowl plugs really easy if don't let warm up before light goes out on dash. If engine healthy should just light right off. Disconnect injectors and clear cylinders dont shut of till warm up light goes off or touch throttle at all think what you think is knock sensor is actual oil pressure. Knock sensor usually in a blind hole As you found out as well when warm up light is on engine throttle is limited, can back fire etc unil light goes out. These sleds will last forever if looked after. I have 32,000 kms on mine. Wish i had power steering like yours. Good score ! Great Video
Im 20min in to the starter spark disaster. On any overheated engine u do 2 things. Check/change coolant and oil. If either is mixing into the other you got a head gasket problem. Second, visual inspection of oil will tell you if the bottom end is waisted. Did he do any of this?
On sensors you can check the ohms with a simple voltage tester. All sensors are is resistance... too much or too little and the sensor is bad. I always test them and can check with spec sheets to see what the range should be. If there isn't info I just buy a new sensor and test it before I put it in and note it in the manual so I, or the next guy has it for referance. I hope that makes sense. TEST THE SENSORS TO SEE IF THEY ARE GOOD OR BAD WHEN YOU TAKE THEM OUT OR SEE A CODE! It will save you so many headaches.
The starter of the year award, cant being that didn't cook. Whoa. Good to see nothing major as of yet. Nice looking sled and looks like a very nice score. You got so many toys, garage is full. And outside too. Dang, i spotted a new atv cover on the atv. Very nice.
just for easy use, that hand fuel transfer pump is a syphon pump. As long as your fuel is above the empty can , one or two squeezes on the hand bulb will start the transfer and empty the tank.
next video, joe replaces a starter on the sled, lol. Also, knock sensors dont have holes in them for oil to pass through, that is a low oil pressure sensor, knock sensors are piezo type sensors that sense a knock or ping by sensing a pulsation or pressure wave through the block. the knock sensor would have been the sensor located above the oil pressure sensor screwed into the block. Joe you aren't stupid, you can certainly fix it, no doubt about that, sometimes( well most times) internet searches can lead you on a wild goose chase, lol. I used to be a yamaha mechanic, and their sleds are a nightmare to work on.
I hope the spark plug in place of oil pressure sensor isn't interfering with anything. Looks deeper than sensor, and made a funny sound when u first started it.
The oil pressure switch is a tapered thread don't put thread tape on it ,it should seal well if it is tight . The knock sensor code could have been caused by the miss firing fouled plugs .or also bad fuel . Just guessing at this stage .Carry on and good luck .
I have never been on or worked on a snowboard, can you remove the belt so you could rev the motor without it wanting to take off on you when working on them ?
Seems like a lot of issues out of such a new machine. It's possible overheating it cooked a few sensors ? I'd probably get it running properly and get rid of it, two stroke sleds at better.
Yea those overheating lights arent easy to notice while riding lol. Had the exact thing happen on a 700 triple but i noticed before any damage. and these 4 strokes are different make sure its getting gas and you got spark. i drive a 2007 apex and i just put on the choke until it starts but make sure its getting gas and that the carbs are cleaned best advice i know alot about these machines.
Crack in block when up to temperature..showing up?? I had a gator that was purging oil and eating coolant… hairline crack inside of block due to a fan issue..
I recommend highly to check out that fuel tank good. It sounds like it has water in the gasoline fuel to me. From setting up.,or A case of bad fuel one. I recommend using STA-BIL fuel treatment stabilizer and fuel injector cleaner.
Good deal! I am going to guess that the knock sensor and the oil pressure sensor got hot and failed just like the coils and plugs. A similar thing happened to my wife's Toyota Matrix years ago; the head gasket blew on a long trip and she continued to drive it until the engine overheated so much it lost compression. I got a donor engine and swapped it in but I stupidly used the coil packs and plugs from the wrecked engine causing the used engine to not run well at all. My advice is that anything that could have failed from overheating is suspect. Maybe a leakdown test would be good to check the head gasket since you are having some things happening with the cooling system.
Well i change the oil pressure sender switch on my mazda 3 and it looks a hole lot like that switch you have right there a knock sensor you call it well looks allot like the one i changed anyways i hope you fixed all the little dings in that yamamaha of yours have a good one my friend ☮️

That is how they are supposed to start, don't crank longer then 20 seconds, swap the plugs immediately. Have fun!
Hey brother, I've noticed in a couple of videos that you're leaving the outboards in the up position on the boats. You should always leave them in the down position in freezing weather. Water will collect in the foot through the exhaust and freeze and bust the foot. Hopefully it's not too late! Just an FYI.
Hope he sees your comment before it's to late good eye brother
Good to know, ill have to keep this in mind
Most people I know that have outboards that keep them in the up position make sure there is no water inside when they store them so if that has been done there shouldn't be a problem
@@186scott It doesn't matter if you drain them. If you leave them up and out in the weather and it rains it goes down the exhaust and collects in the foot where it can then freeze and bust but, to be honest, I don't know that much about boats. I grew up on the largest man-made lake east of the Mississippi, got my first boat when I was 13 and still own one to this day at 60, worked at a marina pumping gas from 13 to 16, drove a marine forklift at a dry dock storge and hauled 35 ft boats around as well as worked on them as a profession for 2 years so, it makes perfect sense to leave an OB or the outdrive of an IO up and take a chance on it freezing rather than put it in the down position and be absolutely sure it doesn't freeze. That's what all my friends do. Your friends are probably smarter than mine. I don't know what I was thinking trying to give some friendly advice to someone and possibly save them some time and money...My Bad! But hey! It'll make great content! 😏
@@ThaFailedMusician not trying to start anything and I am sure like me a few others are surprised by another way of storing them and I do completely understand your way and there are multiple way to skin a cat and I am sure there will be others that agree with you and agree with what I said
You should put the retainer back in your plug socket instead of dropping plugs down into the engine like that. It could alter the plug gap just saying. But great video as always Joe
You did just fine until you said "just saying "
It adds nothing to your point.
Well I said that so people don't think I'm trying to come across the wrong way or like a know-it-all because that's not the case..
just a thought, you added teflon tape to the thread of the knock sensor- could it be you have interrupted its ground path.
when you first pulled that sensor due to leak i was thinking that looked like an oil pressure switch, not knock sensor but i don't know much about those sleds. also..... i don't know who makes starters for yamaha but kudos to them for making a stout starter cuz you were giving that starter hell!
I hope there’s a part three. I wanna see it rip on your land! It sure sounds mean and nasty.
Hopefully the snow sets up better. Here it is too fresh and fluffy. If he can find some hard pack next time, he'll definitely lift the skis and fly vs all the track spin we are seeing here. Motor sounds like an angry bee -sweet and powerful.
100mph club, here we come.
Dude I'm from south carolina and have never so much as sat on a snow machine and for some reason ur snow machine videos arw my absolute favorite ones to watch.
Ps a old plumber's trick was to put ptfe tape on like you did But put more around the tapering end with grease with heat forms a gasket perfect water oil tight 👌
To really get the antifreeze burped out, raise the front of the sled 45 degrees and continue to add until full. The coolant lines typically go all the way back above the track. These 4 bangers are fast.
Jeez, what a battery. I have never heard anyone grind a starter like this.
Is there a reason you don't use starter fluid? It seems to me that you could rule out spark/fuel issues with a few shots of the stuff. It would save a lot of abuse on the starter. I'm surprised you didn't burn that one up.
I wrote it on the previous video of this machine, if it got that hot like the oil was cooking chances other parts are hit hard too.
Like valves cam and Rod and crankshaft and all bearings or oil pump and everything engine-related took a hit.
For a reliable machine, you should take the engine apart and check every piece for heat damage.
Now you could have a machine that breaks down every time you take it for a spin.
There is always a part that fails later on due to extensive overheating, this was a severe overheating.
I wouldn't trust that engine .
Looks like an engineers wet dream the way that motor is stuffed in there. Good luck dude.
48:31 did you have to sneak up on the tired starter😭😭
any yamaha guy is a buddy of mine. my 03 rx1 is still gunning too. it's got about 30k+ miles since it used to be our log hauling machine but the chassis wore out and had recently stuffed everything into a rs vector gt. now she's a cruiser 😊. i love how these machines are all interchangeable its just a lot of work..nonetheless, nice machine bro 👊 happy holidays and you just got a sub frm northwest Alaska 👍
buy up all the yamahas , they are leaving the game after this year. stick that one in the 2vintage museum. shes a collector now. they are fast as anything out there. its a trail beast thou!! have fun with it joe.
Great job getting that beautiful ski up and running. I really was shocked you didn't check the coolant before even firing that thing for the first time. Remember it did overheat lol. Other than that killer deal.
Fantastic work. Bravo for not giving up on it! As hot as the motor got, I'm surprised more sensors were not damaged. Thank you for sharing another great video. Safe travels. Cheers.
Great video, I like you are cutting short the intro to your basic diagnostics, but would like the voice over explaining what and why. I also look at snowmobiles as the biggest waste of money. Paying $7k in 2012 is like 12k today to go play in the snow 2-3x a year? I would rent one instead. Kinda like jet skis, easier to haul than a snowmobile, but i have had three friends rupture tendons and ACL tears trying to get back on them in the water. I will stick to motorcycles and ATV’s
This has been a terrible winter so far in wi for sledding, The grass is barely covered around me and I'm not that far away from Joe's location. Between the high cost of new sleds and declining snow condition its been killing the sport for 50 years.
Snomobiling can be much more than 2 - 3 rides playing in the snow. With hundred to thousands of miles of trails it becomes a destination thing, ice fishing, to a nice restaurant, or an overnight at a hotel etc -a couple of hundred miles per ride at times and a very social thing to do when you all have sleds. I do a yearly three day ride from Manitoba to Minnesota with a group of friends and it's a highlight experience every time. But those Jet skis are more like you are saying, around and around in circles gets boring pretty quick from what I see.
Love your channel bro! Keep at it!
knock sensor will be near the manifold. I can tell how excited you are.. LOL I would want to ride the 1000 too, they are so fun. When you get it going and feel comfortable it will be so rewarding. Check or change all the sensors. More than likely all of them melted. Most are only rated for a certain heat level, they are supposed to fail in the event of overheat. That way you get all these codes and it stops a person from mechanical damage. Fail points are engineered into everything with a gas motor. Your gonna want to put a longer track on it for sure. For the price I would add a long track. Good Score man!!
Man, your runnin a master class on how to burn up a starter!!!
My thought at 14:00. Got fuel, spark and compression. Timing?
This thing must've gotten lava hot for all these components to melt like they did. Even the dipstick, which was separate from the engine itself, was goo. Can't wait to see how it ends with this beast, but I wouldn't hold my breath because all of these melted components can't be a good sign for the engine (and subsequently the one low cylinder). I'm hoping there's no damage to the wiring harness because judging by how hot it got, it'd be a miracle if it's still 💯% intact. Good luck in advance!
That starter is a champ. I honestly can't believe it survived all the abuse. Seriously dude take it easy. More starter burning or endless kickstarts won't make it run if there's other issues like bad spark plugs. This is mechanics 101, you're going to ruin good machines that way
I think you´re just jealous he got so good sled for that cheap..😅😛
It's his he can do what he wants.who are you to tell him what to do 😂😂😂.
Lol I'm not telling him what to do, of course it's his. I'm offering constructive criticism. If you wreck a good machine doing stuff like that, it's hard to make money.
😂😂😂😂
Shut up jerry. Moronic stance. @jerrywilcox9890
Yamahas are famous for fouling plugs from oil injection settings on cable, got to find that sweet spot, you probably know that right? you set it measuring how much distance between the end of outer cable as you pull out from seating, most are around 1inch, easy fix if too rich, temperamental believe just saying, from a nobody up in maine, ya I’m jealous 🤔, love your content!👍🏻🇺🇸
Was the rad repaired where the stud put a hole in it when you bought it?
Use the parking brake if it works.
I normally pull the belt. Just don’t rev it hard enough go close the primary hard.
If you are going to sell it I hope you do very well with it. The sound is fantastic, can't help wondering if that is a YZF1000 engine or similar. What a hassle to get things apart though. Garage costs for repairs must be sky high as I mentioned before. 100mph ? On the snow ? Wow ! Well done that was great to watch, thanks :)
These thing fowl plugs really easy if don't let warm up before light goes out on dash. If engine healthy should just light right off. Disconnect injectors and clear cylinders
dont shut of till warm up light goes off or touch throttle at all
think what you think is knock sensor is actual oil pressure. Knock sensor usually in a blind hole
As you found out as well when warm up light is on engine throttle is limited, can back fire etc unil light goes out.
These sleds will last forever if looked after. I have 32,000 kms on mine. Wish i had power steering like yours. Good score !
Great Video
Not sure where the heat exchanger is but check your track for loose or broken stud before riding or it may happen again
Im 20min in to the starter spark disaster.
On any overheated engine u do 2 things.
Check/change coolant and oil.
If either is mixing into the other you got a head gasket problem.
Second, visual inspection of oil will tell you if the bottom end is waisted.
Did he do any of this?
Holy Cow, that starter😳😳
On sensors you can check the ohms with a simple voltage tester. All sensors are is resistance... too much or too little and the sensor is bad. I always test them and can check with spec sheets to see what the range should be. If there isn't info I just buy a new sensor and test it before I put it in and note it in the manual so I, or the next guy has it for referance. I hope that makes sense. TEST THE SENSORS TO SEE IF THEY ARE GOOD OR BAD WHEN YOU TAKE THEM OUT OR SEE A CODE! It will save you so many headaches.
Well done. What do you do with all of the machines when they're fixed?
Game day champ for a starter and battery. I've never seen anyone crank a engine so long and expect a different result.
The starter of the year award, cant being that didn't cook. Whoa. Good to see nothing major as of yet. Nice looking sled and looks like a very nice score. You got so many toys, garage is full. And outside too. Dang, i spotted a new atv cover on the atv. Very nice.
I was about to comment that the "knock sensor" looked an awful lot like an oil pressure sensor, then you found it.🙂
She sounds like an animal when you hit the throttle. What a score mate! Enjoy your sled and cannot wait until I hear this ripping.
just for easy use, that hand fuel transfer pump is a syphon pump. As long as your fuel is above the empty can , one or two squeezes on the hand bulb will start the transfer and empty the tank.
Some of the things he does confuses me lol
god bless your persistence and your starter
Why would you not put new plugs in when you had the old plugs out?
If you buy a power sports machine that doesn’t run well, don’t you always assume that you replace the fuel?
Burn out many starters Mate?
Does the airbox have to be connected so the carburetors are all sucking in the same amount of are maybe
next video, joe replaces a starter on the sled, lol. Also, knock sensors dont have holes in them for oil to pass through, that is a low oil pressure sensor, knock sensors are piezo type sensors that sense a knock or ping by sensing a pulsation or pressure wave through the block. the knock sensor would have been the sensor located above the oil pressure sensor screwed into the block. Joe you aren't stupid, you can certainly fix it, no doubt about that, sometimes( well most times) internet searches can lead you on a wild goose chase, lol. I used to be a yamaha mechanic, and their sleds are a nightmare to work on.
What a kick-ass deal and that's a beautiful sled
I hope the spark plug in place of oil pressure sensor isn't interfering with anything. Looks deeper than sensor, and made a funny sound when u first started it.
Sounds like a beast that Yamaha. I am curious if the compression of that one cilinder came up again 🤗
When u start it up there is a light on the dash u can’t dhut the sled off intell the light goes off or u have a chance of fouling out plugs
The oil pressure switch is a tapered thread don't put thread tape on it ,it should seal well if it is tight .
The knock sensor code could have been caused by the miss firing fouled plugs .or also bad fuel .
Just guessing at this stage .Carry on and good luck .
I have never been on or worked on a snowboard, can you remove the belt so you could rev the motor without it wanting to take off on you when working on them ?
Seems like a lot of issues out of such a new machine. It's possible overheating it cooked a few sensors ? I'd probably get it running properly and get rid of it, two stroke sleds at better.
Get you one of the harbor freight battery powered pumps.they work pretty good .made of plastic about 2 ft long .
Yea those overheating lights arent easy to notice while riding lol. Had the exact thing happen on a 700 triple but i noticed before any damage. and these 4 strokes are different make sure its getting gas and you got spark. i drive a 2007 apex and i just put on the choke until it starts but make sure its getting gas and that the carbs are cleaned best advice i know alot about these machines.
Is there a sensor in the air box. I know on cars if air intake is unhooked it will barely run
Crack in block when up to temperature..showing up??
I had a gator that was purging oil and eating coolant… hairline crack inside of block due to a fan issue..
I found with my Yamaha is do not touch the throttle until the warm up is done. The plugs can be quite finicky on these things
What brand and model number jump starter do you have or I see you use them all the time with your favorite one
I recommend highly to check out that fuel tank good. It sounds like it has water in the gasoline fuel to me. From setting up.,or A case of bad fuel one. I recommend using STA-BIL fuel treatment stabilizer and fuel injector cleaner.
Good deal! I am going to guess that the knock sensor and the oil pressure sensor got hot and failed just like the coils and plugs. A similar thing happened to my wife's Toyota Matrix years ago; the head gasket blew on a long trip and she continued to drive it until the engine overheated so much it lost compression. I got a donor engine and swapped it in but I stupidly used the coil packs and plugs from the wrecked engine causing the used engine to not run well at all. My advice is that anything that could have failed from overheating is suspect. Maybe a leakdown test would be good to check the head gasket since you are having some things happening with the cooling system.
Well i change the oil pressure sender switch on my mazda 3 and it looks a hole lot like that switch you have right there a knock sensor you call it well looks allot like the one i changed anyways i hope you fixed all the little dings in that yamamaha of yours have a good one my friend ☮️
My guess is the knock sensor is cooked too, replacing should fix it but check it’s connected first.
great job Joe! ya make sure u replace both sensors, or your looking for allot of trouble. these machines are really fast, but can be a pain to fix I hear. check out some vids before venturing too far. I've seen some where guys go crazy with them.....to be young again!
Great video you have so much more patience then i do enjoy you video Great job 👍🇺🇸
