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.

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?

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.

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. 👍

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.
@mark_Hershey 28 күн бұрын
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.

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.

Why did you use a seal puller on the right side but drill the other and pry?
@highlandcycles 8 күн бұрын
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.

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?
@TokyoOffroad 28 күн бұрын
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.
@fredmitchel1236 5 күн бұрын
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....

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?
@highlandcycles 28 күн бұрын
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.

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
@highlandcycles 14 күн бұрын
Sometimes it takes smacking the shaft that the sleeve is on to break it loose. Be careful not to damage anything

@scottphillips445 19 күн бұрын
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 19 күн бұрын
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.
@scottphillips445 19 күн бұрын
@@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

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.
