Dude, I randomly found myself on this trail last year. By myself. The rock garden just kept going and going. Looks like I turned around before it got super gnarly. Good luck with the fix
I honestly can’t believe how good the top looks after you burned it down!! Ball hone that cylinder, throw a new piston and rings it, and rip!! TWO STROKES RULE!!!! 🤘🏼😎🤘🏼
At 260 hours that Y piece would have blown soon anyway...all in all I'd say this machine has been tough as nails, Morgan rides super hard and that bike is impressive. What an amazing place to live, and that shop is so sweet!!! Time for a Trail Tech fan.
@@brandonwl factory recommends 60:1 ratio I used Amzoil at 50:1 but will switch to 40:1 now that I have seen the results. Forgive me for this elementary description if you already understand fuel oil ratios but here it is in a nutshell. The lower the big number the more oil to fuel there is. All manufacturers have a recommendation for their 2 stroke motors. Example KTM recommends a 60:1 ration for their 300 XCW and XC motors. My 1976 Kawasaki KT250 runs 32:1. So 60:1 one is a lot more fuel to oil than 32:1 ratio. Obviously more oil better lubrication but you can have too much and the bike wont run well and it will blow a lot of goo out the exhaust. Injected bikes are set from the factory to inject the proper rate of the proper oil. Many of us dont trust oil injectors and will delete the oil injection system and premix our fuel oil to prevent catastrophic failures. I hope this helps.
@@2WheelsandtheGospel Thanks for the explanation! Didn't realize that he deleted the oil injectors. And I agree im always worrying about my oil pump failing/ getting clogged
You will need a tune on the TBI/TPI to run that much oil. It's also hilarious that you're looking at a cooked motor and wanting to emulate it. 😂 Good chance it was running hot because it's so lean because of the excessive oil.
lol yeah that cylinder is not round anymore. Look at the dark marks in between the bolt holes on the coating. Probably measuring it is a good idea and or put a new ring in and look for light coming through 🤷♂️
You should be brought up on Charges for not Running a Fan on that Trail ! 😂 ‘ Shocked at how good that Top End looks after watching the Ride section of the Video! 👍🏻
i have only owned a husky for a couple of years but the first thing i did (i was made aware of ) was change that t-piece for an all in one samco hose preventative service , its a well known possible failure point here in the EU glad it turned out better than expected !!!!
Ok, maybe you do need a fan. The Myler's radiators are soldered tubes to the fins rather than glued so they cool much better. Keep us posted and good luck.
I have 2022 ktm 300 exc tpi with injector relocation block. How much oil would you recommend for me to mix in the gas? I have not deleted the oil pump and Im currently mixing 80:1. Its crazy that your cylinder didnt get more damage than that
Definitely failure from stock t and no fan. Samco t nice bandaid for this. Honestly its nice it failed that easy with limited damage. Back on trails in no time.
no fan on a PM-AG 300 was your 2nd mistake.... Carbed bikes if you lose coolant you can run with choke on and off to over fuel to try and run it cooler. run choke on fast/road sections on cooler days to be safe.
If it’s that smooth take some 1500 to scuff and run it. Worst case scenario you have to put a cylinder on it! But until then you can ride and enjoy the bike while you are waiting on parts. Good time to bump it to have a port job done on the spare cylinder. I’m gathering parts to build a yz250
It's a 2t. You don't need the cross hatch. It's not a 4t. Some of the best engine builders are going to great lengths to get a mirror smooth hone for the best longevity and power out of their built up 2 strokes.
That is new. No real vid on it yet. It is from Enduro 1. They are a hard enduro specific company run by Ben Nicholson of 1st Track Motorports. check them out at 1sttrackmoto.com/highlandscycles
Ma man, you need to get the tripod closer, couldn't see the tee pieces and other parts coming off, kind of defeats the purpose. rebore and plate is needed imbo
I seized up my 96 husky. Gave it an acid bath and it looked brand new. Ran it for another 1000 hours with no issues and pulled hole shots at the track.
KTM put a weak stator on the bike that doesn't support a fan or light. Nor do they even put the wiring for the fan on the xc. They know darn well these bike get hot and need a fan.
40:1 is less fuel. Might seem insignificant but I would be willing to bet if you had run 60:1 and bumped up your fueling you would have run cooler temps. Guessing the plastic Tstat cracked after the heat.
@@highlandcycleshow did that work out for you? "Hey guys, I melted my motor though flat out abuse but this extra oil surely saved the day!" If you don't have a fuel map to support the extra fuel that needs to be sprayed you're going to run lean. Running lean gets the piston hot and swells it in the jug reducing clearances and pushing oil film out. But no, "throw more oil at it" surely worked. Along with riding like it's a race when you could have taken a break and let the damn thing cool. More video clicks if you're dumb. So keep being dumb? 😂
@@highlandcycles plastic water parts are just a hot cycle from failure but generaly found keeping them in the cooler ranges gives them a chance at life.. have seen bikes cook when mud and tail wind riding limits cooling but generaly 1 or 2 fans slow the cooking until fluid loss.. motorex saved the top end.. 👍
It's not like the bike quit running on you you put fluid in it and it never ran all the way out I knew it was gonna be good I would change that t piece and just put it back together that bike will run for a long time still
Mine runs cooler than anything else I've had. 1 thing to note. Just cover the cores with water. You don't need it to the top of the filter neck. Every bike I've ever had will push coolant out until it equalizes at the top of the cores.
15k no warranty so people whom spent their last hard earned dollars is just S.O.L. #shame and disappointed and discouraging and sad bc everyone is not fortunate like this guy in video to work on yourself. 🤷🏽♂️🤷🏽♀️🤷🏿👎🏿🫵🏼

glad I went w/ the 24' te300pro / xcw and didn't fark with an aftermarket tune or hi comp heads or anything. bike just runs perfect .
Please adopt the 3S rule. See Steam Stop!
Hahahaha, nah!
This was awesome lol. Your giggles as you continually dug deeper were cracking me up 😂The clip of you riding it... You were abusing that thing hahaha
Yeah, I was so blown away that it wasn't melted.
Nice overheating clip. You should put a 250 topend on it!
I was expecting way worse inside that cylinder 🤘🤘 tough bike

I road horseshoe and tank 7 this year. It was awesome and they are very rocky trails. Maybe sometime I can ride with you Morgan!

That’s exactly what’s happening

Yessir
Definitely a win for KTM in my book. As they need all they can get right now if you know what I mean
I’m blown away at how good everything looks. I’m switching to 40:1
what does he mean by running 40:1? That's a normal ratio you run on a carbed bike?

me too

Oh yeah, I will be for sure. I am sure its not perfect
@@highlandcycles sometimes it’s hard to turn off my machinist brain and just say it doesn’t need to be perfect it just needs to work.
Wow what luck I thought it would be baked for sure the way it was huffy steam on those gnarly hill climbs, nice save!!!
You should be brought up on Charges for not Running a Fan on that Trail ! 😂 ‘ Shocked at how good that Top End looks after watching the Ride section of the Video! 👍🏻
Those tusk lifts are nice.

Pretty lucky. Bore sleeve looked normal. A new top end and fan kit, and your back in business. Motorex oil is liquid gold insurance. 👍
100%
sorry brother. impressive that you didnt end up with worse damage.
Skip the fan if you can find a Myler's HD radiator, those things are cool running!
Ok, maybe you do need a fan. The Myler's radiators are soldered tubes to the fins rather than glued so they cool much better. Keep us posted and good luck.
Love yer videos. TBI bike knowledge before I get my 25 TX300 by years end. 🤞
For sure. Replace the T pipe
I have 2022 ktm 300 exc tpi with injector relocation block. How much oil would you recommend for me to mix in the gas? I have not deleted the oil pump and Im currently mixing 80:1. Its crazy that your cylinder didnt get more damage than that
I am not sure. You don't need to add much if you have the relocation kit.
looks like you dodged a bullet there fresh piston gaskets should be good keep up the great work
Definitely failure from stock t and no fan. Samco t nice bandaid for this.
Honestly its nice it failed that easy with limited damage. Back on trails in no time.
Ooooh right it did get hot on that gnarly hill didnt it 😂.
KTM for the win!🤘🤘🤘🤘🤘💯
Watched the ride, that motor was WAY hot for a very long time. Heat as you well know kills stuff.
That's exactly why I run 40:1
no fan on a PM-AG 300 was your 2nd mistake.... Carbed bikes if you lose coolant you can run with choke on and off to over fuel to try and run it cooler.
run choke on fast/road sections on cooler days to be safe.
Sick! How's the bottom end?
Amazingly good

That is new. No real vid on it yet. It is from Enduro 1. They are a hard enduro specific company run by Ben Nicholson of 1st Track Motorports. check them out at 1sttrackmoto.com/highlandscycles
I guess the muffler was a figment of my imagination and doesn't really exist.

I would buy yourself a lottery ticket this week so lucky👍
Agree

They know darn well these bike get hot and need a fan.
That's pretty amazing. You definitely got lucky. My YZ is way worse than that.
I know. Crazy
How many hours do you have on it? Forgive me if you said it and i missed it
No worries. 260
I think any other bike would have fared the same assuming same oil and ratio.
I’m sure the head is warped.
40:1 is less fuel. Might seem insignificant but I would be willing to bet if you had run 60:1 and bumped up your fueling you would have run cooler temps. Guessing the plastic Tstat cracked after the heat.
It would have been more fuel but I don’t think enough to really make a difference. The extra oil though could be why the crank seems fine
Geese your hard on stuff
Yep
A plastic T failed.? Not surprised...
when you're running 40:1, aren't you running more lean (aka more hot)?
Technically yes but there is more oil to lube which can save a motor that is out of water.
@@highlandcycleshow did that work out for you?
"Hey guys, I melted my motor though flat out abuse but this extra oil surely saved the day!"

More video clicks if you're dumb. So keep being dumb? 😂
🔥
I didn’t see how you disconnected the power valve? Did I miss that?
Its in there I believe.
So your saying the plastic failed due to no fan.. self inflicted by my guess.. 😂😂
For sure. But not sure if it would have survived even with a fan. I’ve made a bike boil even with a fan.
@@highlandcycles plastic water parts are just a hot cycle from failure but generaly found keeping them in the cooler ranges gives them a chance at life.. have seen bikes cook when mud and tail wind riding limits cooling but generaly 1 or 2 fans slow the cooking until fluid loss.. motorex saved the top end.. 👍
What kind of bike stand is that???.
Tusk. bit.ly/2idns0Q
Bought mine at Auto Princess here in Canada! Best stand I have ever bought
@@timclarke9346 tusk from Rocky Mountain bit.ly/2idns0Q
Will this be the second or third top end on this engine?
Second
Second I’ve put in it so 3 total
Why did you take the fan off?
I’ve answered that a ton. Dig through
@@highlandcycles I would replate the cylinder. Money is nothing to a guy like you! Blatantly overheating your main machine is a major motocross foul!
Thought you had a tsp head on your 300xc?
I do
@@highlandcycles didn’t look like the tsp head my bad
@@highlandcyclesit got so hot the color of the head wasn’t obvious that’s why I didn’t notice it
@@ericcustard8100 yep.
So you lost compression when the head seal melted and that's it? 🍀
As far as I can tell so far
@@highlandcycles maybe they designed that as a failure point to save the engine. Seals melt, no compression, engine no go. 🤔
It's not like the bike quit running on you you put fluid in it and it never ran all the way out I knew it was gonna be good I would change that t piece and just put it back together that bike will run for a long time still
It actually did quit. It blew out the head o ring eventually.
KTMs seem to boil over more than other brands.
I don’t know. I’ve boiled everything
Mine runs cooler than anything else I've had.
1 thing to note. Just cover the cores with water. You don't need it to the top of the filter neck. Every bike I've ever had will push coolant out until it equalizes at the top of the cores.
Luck, our ktm quality?!
quality and the fact I ran 40:1
Why would you keep revving the crap out of it when it was smoking like that
Had to get up the hill.
He's actually just doing it for the clicks.
He could have easily stopped and let it cool. But that wouldn't be cool enough to make a video about. 😂
Piston too tight, overheated
Hahahaha. Nope. This bike has 260 hrs on it. 160 on this piston
KTM abuse. Don’t blame the bike.
I didn’t.
No fan? come on Morgan you know better than this.
I don’t think the fan would have saved the T piece honestly
