I learned the value of not over tightening fasteners long ago. Don't have patience for stripped threads. No. Some trick jetting all but cured the drool on my 2002 KTM 300. It was beyond rich when new.
I have been getting increasing spooge the past few months and plug fowling, ECM was flashed last year, my first thought was crank seal but level never drops between changes. Pulled CCP sensor and oil was dripping from the inlet, swapped in a new sensor and it cleaned right up with minimal spooge so far.
I really like all the how-to videos. Help so much. I looked on Rocky Mountain and they don't have an o-ring for the clutch side. Is it the same as the stator side? Or maybe do you have a part number?
60:1 motorx back in 2014 KOM, no cooling fan, trailtech full telemetry, sustained high 200F , peak temp spike of 328F running Evans. Zero engine damage except crank seals went out 2 seasons later.
Another theory regarding the spooge.. check out the recent vid from Pinit racing, where he checks his xc for vacuum leaks using a bung in the exhaust port and the inlet boot. Applies positive pressure and uses soapy water to check for leaks. Leaks would account for bottom end bog and spooge? Akin to rich condition?
Crank seals on these recent bikes are an issue for sure! My 2022 GG EX300 was likely leaking from the get go and I don't think the bushing was in the correct direction.
Mine splooged bad, but a top end, a flash to updated map, or new fuel pump has cleaned my bike up. All this was originally done to find a random bog. Pretty sure it’s the fuel pump that fixed it. Someone said ktm updated the fuel pump, part number ends in 200 now. Mine is a 2023 300 xc also. Bog started at 25 hr, have 42 now.
Always great tips and advice, good luck on your test ride and it'll be interesting to see if it's still spitting out fluid . It's funny how if you could of made money from it burning to the ground you would have, cos you was so angry at the bike for its failure. 👍
Very curious if this stopped the excessive spooging. Mine has spooged since i got it, just recently did the TSP tune, only 1 in ride since but didnt seam to help. Im wondering if mine is leaking also. Mines not using a measurable amount of oil between 10hr oil changes either….
Hey Morgan, you’re seeing excess spooge because of the Spanish fly racing spark arrestor. Remember, you’re shortening the core and removing quite a bit of packing to install it. I also have a 23 300 XC and if I run my pro circuit shorty (no spark arrestor) It never spooges. My first ride with the stock muffler (new) with Spanish fly racing was a fast race and it spooged a lot.
My 2017 TE300 with 190 hours burned about 130mL of oil in the 17 hours since my last oil change. No external leaks. Bike runs well, spooge is normal. Replace the seal or keep an eye on it?
During the compression stroke, the piston moves up, creating a vacuum in the crankcase, which draws a fresh charge of fuel and air into the crankcase via the reed valve. During this part of the cycle if the right side crankshaft seal is leaking, transmission oil & air can also be drawn in to the crankcase from the transmission.
When i go to take that distance bushing thing out its so stuck and i cant even take it out with pliers. It almost looks like the woodruff key is stuck to it and blocking it from coming out so now ive been fiddling with that tying to budge it but it will not move. Now the key is pretty dinged up - is that a big deal? How can i get that sleeve out? Any insight is appreciated
I tried that and nothing. Like i saw it looks like the key on the shaft is connected to the ring for some reason. Can i dm you somewhere to show you a picture?
Ive seen some guys drive the tip of a drywall screw in the seal and pull it right out. Not sure if theres any behind the scenes voodoo but seems like a cool hack. Hiw many hrs on the xc?
How many hours did you get out of the XC300 piston and rings? It is possible that the clutch side crank bearing has play in it causing the crank seal to fail. However: if the bearing is bad you usually get gear oil burning like a forest fire
@@highlandcycles I personally would guess that the bearing is good and that the seal was the main problem. I would guess that 150 hours is the time for a piston
Just found out KTM is owned by Baja 300 Austrian technicians laid off what the heck is going on? We are told by actual KTM technician they would not touch a KTM anymore with your 10-ft pole KTMs 300 are blowing cylinders off or 2024 Husqvarna was leaking oil so bad out of the shift seal they replaced it twice now. Is this true? Please tell what you know about this.
Sad days when the maintenance guy doesn't do his maintenance. 😢 Got over 200hrs on my stock sherco clutch. 900ml of atf fluid changed about every other week. Bike is just hitting it's 1st birthday
@highlandcycles understand. A few more years of slaving away, get those boys growd up and sent off you'll find some more time hopefully. Maybe next year I'll find some time to travel to a few of the races westward of me. I'm in southwest Missouri. Gonna do the entire Blackjack series for sure. Try to win the B40+
How often do you change transmission fluid? To me, it makes no sense what answer I get from people. On the 300xc, so many will say ohhhhh don't change the piston till at least 100hrs the manual says 50hrs and ktm just wants you to buy pistons. Someone will back that up with, well lol ktm is saying that in race conditions you need to follow the 50hrs roller for pistons. Then I'll see people say oh yeah replace your transmission oil every other ride so at most 10hrs. Which makes no sense when ktm manual states 40hrs for transmission oil. So, on one end people don't change pistons because ktm is trying to get you but also change your oil way more than ktm suggest? Makes no sense. What's your rule of thumb for transmission oil?
Haha. I get it. Here is my answer. Trans oil every 10-15 hrs. Depends on how hard I am in the clutch in those hours. Piston 100hrs. I’m going 150 on this one as a test but 100 is safe and not too early in my opinion
@highlandcycles also heard you say in this video or another, do you really run 40:1? My 2022 tpi has a the full TSP setup and changed over to mixing my gas and love it but run 50:1 which is more oil than what people recommend just to be safer as im on the pipe a lot. I'd rather run 40:1 but figured it'd be a touch lean. Guess I could add some fuel with the ERM.
Mystery problem,Foul a plug on a Beta- oh they are trash and unreliable. Crank seals and can’t keep a clutch running- oh do please tell we all have similar problems on these wonderful bikes. 😂 jk- kinda
I would clean and oil air filter long before it looks that. But maybe your into engine polishing and creating race clearance ...for you have money and experience... Tranmission oil i change about every 5 hours..... May go longer...but if narly trail...and clutching alot maybe sooner....
My clutch cover has a oil glass...I'm glad it's there. I bought from slavens years ago. 300xc
Glad you got it figured out. Good luck this weekend!!!

Thanks for all your videos and Love the RZ350 in the background I gave $800 bucks for one back around 1992 wish I still had it. Best to you
great job as always lad keep up the good work

It’s different. I’m out of town right now.

That video blew my mind! Im like 🤔🤨!!!
lol…Rocky Mountain in ky is my local dealer…they have a lobby for locals. Everything is always in stock. Plus they have a scratch and dent corner.
Crank seals on these recent bikes are an issue for sure! My 2022 GG EX300 was likely leaking from the get go and I don't think the bushing was in the correct direction.
I was hopping you made a vid of how you did the seals 🔥
Thanks for the video really liked it great tips
Anxious to hear if you have less spooge now.
I do measure the oil when I change it because I don’t ever remove the level bolt so far no problems this way 👍👍
Nice

At 18:22, what's that on the front rim at the 8 o'clock position. Is it dirt, or some kind of weight, or ...?
Hahahah. That’s a piece of mousse. When I installed that tire the mousse balls were pretty hammered and that’s a chunk
You're welcome on the Nord Lock.🤘
Thanks. 🙏🏻
How do you remove the crank seal on the stator side if the previous owner used Loctite? I have tried a heat gun. Any other thoughts?
Probably have to use a torch
Very curious if this stopped the excessive spooging. Mine has spooged since i got it, just recently did the TSP tune, only 1 in ride since but didnt seam to help. Im wondering if mine is leaking also. Mines not using a measurable amount of oil between 10hr oil changes either….

Good to know
Can the seal on the other side of the case cause spooge as well?
@@nickstevens7369 not normally
I've seen the clutch rod actually melt on the end.
My 2017 TE300 with 190 hours burned about 130mL of oil in the 17 hours since my last oil change. No external leaks. Bike runs well, spooge is normal. Replace the seal or keep an eye on it?
I’d replace because that’s plenty of hours.
Hi mate, hope you have it sorted now. Question, isn’t the crank pressurised- meaning it would pushing out? Or does it suck in on the seals?
During the compression stroke, the piston moves up, creating a vacuum in the crankcase, which draws a fresh charge of fuel and air into the crankcase via the reed valve. During this part of the cycle if the right side crankshaft seal is leaking, transmission oil & air can also be drawn in to the crankcase from the transmission.
Why did you use a seal puller on the right side but drill the other and pry?
Great question. On the right side you remove a bushing and then a seal puller fits in there. On the left, there is no gap to fit a puller.
When i go to take that distance bushing thing out its so stuck and i cant even take it out with pliers. It almost looks like the woodruff key is stuck to it and blocking it from coming out so now ive been fiddling with that tying to budge it but it will not move. Now the key is pretty dinged up - is that a big deal? How can i get that sleeve out? Any insight is appreciated
Sometimes it takes smacking the shaft that the sleeve is on to break it loose. Be careful not to damage anything
I tried that and nothing. Like i saw it looks like the key on the shaft is connected to the ring for some reason. Can i dm you somewhere to show you a picture?
Ive seen some guys drive the tip of a drywall screw in the seal and pull it right out. Not sure if theres any behind the scenes voodoo but seems like a cool hack. Hiw many hrs on the xc?
That works.
212 hrs
what is going on whit your front rim????
Hahahaha. I hit stuff hard
Tell us about the ding on the right side of the front rim.
Oh man, I don’t know. I hit lots of stuff hard.
I guess I'm ordering seals mine sponges after the tsp flash too
How many hours did you get out of the XC300 piston and rings? It is possible that the clutch side crank bearing has play in it causing the crank seal to fail. However: if the bearing is bad you usually get gear oil burning like a forest fire
100 out of the first and I’m going to 150 on this one to see. I felt the bearing and it feels tight. We will see.
@@highlandcycles I personally would guess that the bearing is good and that the seal was the main problem. I would guess that 150 hours is the time for a piston
@@highlandcycles what is your opinion on wiseco piston and rings?
@@scottphillips445 I like vertex better
It spooges because it doesn't have the drain port from the power valve anymore it all goes out the exhaust and in the power valve covers.
Was that 8 lb ft or 8 nm?
Foot pounds
Do you think the crank shaft seals should be replaced regularly?
Normally, only when doing a crank.

when it goes high black. If you slip the clutch heaps like me it's every 4-5 hours on the beta

@@DDRDK I do run 40:1. Always do.
Beyond me why there’s no dipstick for the gearbox on a 2 stroke
Or sight glass??
Dude my crank seal has be bad a few months I keep adding oil lol 😂
The spacer should have been made thiner and the rubber seal made thicker to give it more meat. My two cents.
Mine dont spooge much
Seems a little early for a leaky crank seal.
I agree
100nm for clutch basket and crank gear nuts?
NAHHHH lets just use the small impact drill
That “small” impact is good for over 80 ft lbs.
Mystery problem,Foul a plug on a Beta- oh they are trash and unreliable.
Crank seals and can’t keep a clutch running- oh do please tell we all have similar problems on these wonderful bikes.

Hahahaa. I hear ya. But if you knew what the beta was doing now you might not disagree with me.
@@highlandcycles I will stay tuned in, I appreciate all your material 👍🏼
Not for nothing…..better than leaning it out and seizing the motor up
100%
I would clean and oil air filter long before it looks that. But maybe your into engine polishing and creating race clearance ...for you have money and experience...
Tranmission oil i change about every 5 hours.....
May go longer...but if narly trail...and clutching alot maybe sooner....
Hahaha, that can happen in one 4 hour ride around here. Our dirt is like moon dust. And there is never any dirt on the wrong side
