I love how this entire video can be sumed up as: read the damn book! I see people take off all the time on cold bikes and wonder why they're having cylinder issues
Just checked the oil pump output on my 2018 Husky TE300i (Euro bike). The sequence is quite different from the one shown on the video. The pump gives pulses only for a few seconds, giving 1ml of oil. Hence I gave it a go 5 consecutive times and collected the oil in a syringe. What I got was total some 6 ml. My bike has 35 hrs on the clock. These videos are superb - thanks!
I’m experimenting the same results in my 2019 300i. Clicks ONLY while the throttle is held wide open. If I wait 5 seconds and release the pumps stops. I didn’t measure the output but it wasn’t 6ml.
My 150 does 2.5ml on the priming cycle and 3ml with a modded pump. Easy way to test is just fill the oil tank to the top and run the priming cycle and you can see the oil drop.
The value of simplicity should not be ignored. 2-strokes are very simple. Water cooling had big benefit As. EFI/TPI benefits will be neglible if it causes any grief at all. I have never had a carburetor fail. Except for the diaphragm type on weedwhackers. And maybe a float got stuck once. Never was stranded by a bad carb
All anyone says to me is 'ohhh you've got a tpi, it will seize soon' actually making me think now 🤔 but my first hand experience with tpi's has shown they are perfectly reliable.
I enjoy watching your videos and the droll humour too. As a retired motorcycle mechanic and tuner and ex dirt racer from 40 years ago,I'm amazed how much I've learned about modern bikes in the 18 mths since I started riding again.Bought a KTM 2019 300 TPI which had numerous issues which are all resolved now. I'd like to offer a small input for your consideration. I see a label marked E10 unleaded on your bike and have a couple of suggestions. I raced for years on Methanol and petrol and had many issues but was never beaten to get the best results and engine reliability. KTM advises to use unleaded 95 which gives a higher BTU/ml than either E10 95 or unleaded 98. E10 has much lower BTU/ml and requires more fuel to travel the same distance and produces less torque than 95. E10 attracts moisture and cannot be left in the tank for long,especially if not full.The worst effect is on TPI fuel pump and filters so that O rings perish and wreck the pump. Moisture in fuel also promotes organic moulds and blocks the fuel pump screens and both filters too. Lastly unleaded 98 is not good for two strokes as the added Octane boosters and bore cleaning agents and Zinc upper cylinder lubricants are bad for electrodes on NGK TPI plugs,which become contaminated and short out and will not start or run well. EGR codes will appear but after their clearing,a new plug is still required to start again. Lastly the NGK TPI extended tip plug has a 2 degree ignition advance advantage over other recessed Platinum or Palladium plugs,which means more torque and better consumption. Keep up the great reports and tips on riding and bike servicing. RV
Very interesting and professional approach, I love your videos. I just did a test on mine and there’s a discrepancy between results, wondering if weather conditions and time of the year can make a difference
Our brand new 2024 SX125 completely lost compression at 10 hours during a motocross race. Turns out the piston had huge chunks out of it above the top ring. The head had cracked. Took to dealer since only 10 hours, they say caused by gas/oil mix (which was exactly what they recommended). We heard the thermostat has gotten stuck on these 24 SX125’s and not put coolant where it needs to go and caused this. Not sure what KtM will do, but this seems to be a huge defect
I took their oil pump and adapted it to a 2004 kawasaki 220 super moto. Honestly electronic oil pump for a 2 stroke, it's about time. Skidoo does it on sleds.
Great video and informative like always. I'll take a carb all that check this check that clean this. Never have to do any of this on carb models. I do agree on starting and warm up method I've seen to many people abuse their bike reving the crap out of their bikes.
When I had this bike I was using a GET ECU, which I understand was mapped to inject more oil than the stock TPI, for use with the GET injector relocation kit which I'd also fitted.
With TBI the engine will tend to run cooler compared to TPI as the fuel passes through the crankcases. Also TBI allows you to run premix which I consider more reliable than oil injection.
In our ride group 4 out of 10 TPI bikes have seized in the last 6 months. One had less than 40 hours. None of us race or abuse our machines. None of us received any help or compensation from the dealer or manufacturer. The typical out of pocket repair cost at the dealership for this failure is $2000-$2400. I believe that cold weather operation is a major factor in these premature failures. Unlike snowmobiles, the oil tank is not enclosed or heated. All the failures indicated seizure on the intake ( cold) side of the piston. This is the side that receives the oil injection. Perhaps using snowmobile 2T oil during cold season is a good idea. I also question the frequent piston replacement suggestions. We have inspected a handful of pistons at 250-300 service hours of trail riding use and found them within spec. One outlier has seen 430 hours and still has good compression and doesn’t smoke. As I recall in your previous video that your own piston looked very serviceable at 150 hours or so. For me a significant drop in compression would indicated replacement time more than a set number of hours. Careful measurement of ring gap and cylinder taper upon disassembly would quantify actual wear. Old habits die hard. There have been significant improvements in metallurgy and production tolerances over the past few decades. Thanks for your video series. You bring an engineer’s perspective to educate and inform the public, a valued perspective.
That’s interesting Garth - I’m in Utah and ride it quite cold weather throughout the winter as well. Beyond snowmobile oil I wonder if there is something else that we could do to protect the motor. I had a thermostat delete but put it back on as my bike would never go about 120 degrees
@@joshhancey3810 In my experience the TPI bikes definitely run cold. My TrailTech radiator fan assembly has a digital gauge. It was common to see the coolant temp drop below 100 degrees Fahrenheit on downhill runs. The bike would act noticeably cold too. Upon disassembly the seized bikes all had oil present, especially around the reed block. I speculate that these motors and cooling systems were not properly developed for cold weather operation. Oil will not lubricate properly at low temperatures and high loads if it has trouble getting past the reed block to the piston and cylinder. All our seizures have been on the cold side of the piston ( intake side). Jeff Slavens has a good video about this. He has fitted multiple temp sensors and also reports cold coolant temps. Jeff recommends blocking off one radiator for cold weather operation. He certainly knows more than me about this subject.
To clean the oil pump without disassembling it, I thought about putting degreaser or brake cleaner in the oil tank and running several cycles like that. Afterward, I would put oil back in the tank and run more cycles, this time with oil, and then reconnect the pump. What do you think? Has anyone already tried something like this? Should i give a try?
I do not have any experience in cleaning these oil pumps and do not know the internal construction, or type of seals used so it's difficult for me to comment on whether doing what you're proposing is safe, or not. If your oil pump has a good number of hours on it and you're concerned about it's performance, my recommendation is to replace it with a new one.
My ‘20 TX300i put out 10ml oil in 60 seconds (short pulses). I haven’t seen anyone reporting this much output (usually around 6ml). Thoughts? I did have the dealer update the map summer ‘22
Maybe the updated map injects more oil during the priming sequence (pulse length might be different). Now you have a reference you can monitor it over time. A significant decrease from your reference would typically indicate that the oil pump needs replacing...
Great Video! All the videos are helping me so much with getting to know my 2022 Husky te300i. I just ran 3 oil pump sequences attempting to clear a bubble in my hose.. turns out I should have been working in a better lit shop as it was just a dirt spot on the backside of the hose haha! Would all of that oil just dumped into my throttle body? Should I be disassembling and cleaning prior to starting the bike? Thanks
My sons 2020 husky150i seized after 9 hours. The dealer has had the bike for over a month and no help in site. Parts on back order. Husky/KTM has not said whether they will help or not. Fingers crossed.
I've just ticked over 35 hrs on my '22 250 TPI bike and I just used the 1st liter of Oil... It worries me that Im running with too little oil. I have understanding that the bike auto regulates itself but how can I be sure?
Is this the standard for all KTM 300 XCWs? I have a 2019 KTM 300 XCW TPI and it is very low 1.1ml. I just purchased this bike used and I am checking it out.
Mark, excellent video as always. What brand of water proof grease do you use for the rim of the oil filter and what do you use to clean the filter when it’s time to do so.
I use BelRay Waterproof grease for the air filter lip. To clean air filters I first use kerosene, let air dry, then use Oxiclean in hot water. This gets them really clean.
Thank you! Also how do you get the internal area around the cylinder head and wire looms and cables so clean. I use simple green but there is still a brown dirt residue. Short of taking a damp rag and rubbing all the interanal area down I don’t know how guys keep that area so clean. Is there a foam or special way to do it. I never pressure wash so I’m at a loss. Any suggestion is appreciated.
Great video. Please can you confirm the following. Must you first hold the throttle wide open before connecting the dongle to prime the oil pump or must you connect the oil pipe to the measuring container, connect the wake-up dongle and then open the throttle for 5 seconds and then the pump will activate and run a cycle.
Pleased that you like the video. To start the oil pump priming sequence you must first hold the throttle wide open, then plug in the wake up dongle, wait at least 5 seconds, release the throttle and the sequence should start.
Are you asking about draining the 2-stroke oil from the tank and how to clean/replace the oil screen? It's covered in the KTM Repair Manual in the Lubrication Section. The method is to remove the throttle body, remove the oil pump, drain oil from the tank, remove the rubber boot on the bottom of the oil tank and the oil screen will come out of the bottom of the tank.
How important is it to clean the oil screen? I have 230 hours on my 2020 and I am on my second oil pump. I have neglected to clean the oil screen when installing the new oil pump(s). thanks Brian
Got a 2022 TE300 I , want to wake up my ECU for oil priming test , any idea of bridging plug (EURO 5 ) at connector without buying wake up plug , At the moment Husqvarna are out of stock down under
My ktm exc 300 2022 oil pump not woorking, i change with new one and still not working… whats thats problem, i’m check fuse and relay all goods Who have some experience in this case, waht it’s the problem thanks
Did you find the issue. It must be an electrical issue. Check the wiring and connector. If the oil pump isn't working you should see a blink code on the dash display
The pump is Mikuni ESOP-04. Has anyone found where to source it - apart from the ridiculously expensive OEM pump from the dealership? It must be installed in a number of other engines...
Is there anything else I need to do when getting the old ECU in there? I swapped back (unknown food ECU) and I don’t have a measuring tube, but it’s not looking good lol
The best thing to do is like I did sell that TPI bike and wait till the throttle body comes out 2023 and go on with your life.... Every hard Enduro race of the professionals they stripped that stuff off of their bike and put a carburetor on blocking off the electronics that is a fact none of those hard Enduro championship races are done with TPI that's why they're getting rid of it... it failed way too many times
Anyone tried this with the GET ECU for a set length of time?? I just wanted to compare to what mine is pumping. I believe mine pumped approx 2.75 mL of oil after 2 min of holding the throttle fully open with the dongle plugged in.
I have a 2019 te250i with the GET ECU, so what is the recommended testing with the get then? What specif time should I be holding the throttle down for and how much oil should I be getting?
Why am so nervous to pull the trigger on a TPI? Case of over researching possibly. I just don’t want to be stuck looking at bike that’s seized, maybe I should just go 4t route?
Depends what riding you're doing. I much prefer 2-strokes for the terrain I ride, but if you ride more open, higher speed a 4-stroke might be a better choice. If you like the TPI then go ahead and buy one. Maintenance is easy and cheap to perform yourself.
I just did measurement in 7degrees warm garage ( i dont know how much that will affect the result). I got 5.0-5.9ml, and my bike is EXC 250 TPI 2020, with 300EXC map(gives bit more torque). So i dont know is that good or bad and should i have something different than 6.3ml since bike is 250cc?
Dear riders, i have 2021 250 Exc Tpi. I tried to make the oil priming with the wake-up connector bought from the dealer (the red and black one) The oil pump did not test/work as in video. I tried more than 40 times with different time intervals 4-7-9-12.....25 seconds. I have the standart ECU. I watched all the videos and read the manual, Did exactly the same. Do you have same oil pump problem? If yes how did you solve?
If your bike is a 2021 TPI with stock ECU it should prime in exactly the same way as shown in the video (set number of pump cycles every time). I suggest you discuss with you KTM dealer.
recently bought the 2022 model, 26h in and i had a damaged cylinder head and piston. bike was not used in motorsports, only for casual riding and some soft enduro. any tips on what should i do or check? i tried to contact ktm but they said i only have 1 month warranty after purchase and 1 1/2 months passed since i purchased so my warranty is currently expired.
Chances are that the damage happened during cold start, these tpi bikes can not be revved at all until hot and they take several minutes at idle to warm up depending on outside temp. From what i've seen the people who are meticulous about warm up do not have any issues. Not your fault as there wasn't enough awareness about this to owners until recently.
Very informative ,great site ...But fuel pumps ,oil pumps ,crankcase pressure sensors etc etc fuel injection has no place in enduro bikes .Great idea on informing ktm on the problems you may have encountered but that won't get your bike back to your truck. And the bullshit KTM had to introduce TPI to pass Euro emissions ...Beta,TM,reiju all seem to have met Euro standards without TPI. It seems KTM introduces technology that isn't properly proven akin to VW .I'll take Carb , Kickstart and KYB suspension anyday and make it back to my truck every time.Anyway great site ,I'll continue to watch irrespective of the KTM content
@@samuelyeet6006 The sherco,TM Beta and Reiju are all carbed or offer a carbed version in their premium bikes.Yor statement is totally incorrect you plonka
@@ktmkaos by other hard offroading machines I meant things with more then 2 wheels lol yes carbed, but they still have oil injectors... it doesnt have to be fuel injected to be oil Injected lol you "plonka"
Mine had a seize around 80hrs, didn't realise till I took off the pipe off to clean, looked into the cylinder saw the intake side of the cylinder was badly scored
@@TokyoOffroad got the bore honed it was barely saveable, new piston, also put a two stroke performance tune on it for extra oiling. Bike is a 2018. I did the oil pump priming sequence 3.1ml in 30 seconds, yours was over 6ml was that a 1 minute test?
Yes, that's the same as I measured so should be fine to continue using the same oil pump. I would say if the volume drops 10% (below 5.7ml) then it would be a good idea to change the pump. Note that this is not something specified by KTM...
With a GET it will cycle the oil pump as long as you keep the throttle open. As such you need to decide on a time period to do your measurement and keep the throttle open all the time. I prefer the stock ECU priming sequence method for this test, although the GET method is great for just clearing out air bubbles from the hoses after you’ve had it disassembled for maintenance work and means that your throttle body doesn’t get swamped internally with oil.
Anyone tried this with the GET ECU for a set length of time?? I just wanted to compare to what mine is pumping. I believe mine pumped approx 2.75 mL of oil after 2 min of holding the throttle fully open with the dongle plugged in.
I unfortunately bought one of these pieces of crap. 2022 KTM 300 XC TPI. The dealers cannot fix it and KTM will not cover anything under warranty even though it ran like shit from the 1st day. I will never buy a KTM again. I was warned I would regret it.
@@samuelyeet6006 No, the 2017~2021 all KTM EXC and XC-W models are fitted stock with XPLOR forks. The XC and SX models are fitted with AER. Stock the XPLOR forks work well at low speed, but tend to blow through the travel too quickly and don't feel stable at speed. Over the years the valving in XPLOR fork valving has changed with some improvement (2017 was way too soft, 2021 is much better), but I have modified my bikes...
$12g bike that needs $2g more of engine hop up's and its very own video on "how not to seize"... Yea i'll stick with my Sherco 2t. Best bike out of the box.
They don't actually need anything. Half the people are just idiots and the other half listen to idiots. I've beat the piss outta my TPI and over 120 hard hours.....only issue in all that time was a failed crank case pressure sensor ($45). It's time for a piston but it still runs flawless!
Bro they dont need anything, people just want more power, you act like carb people dont drop 1k on a lectron or smart carb, another 20 hours tuning the bike, and another 1k in other performance parts, it's the same for both of them
I had No idea Lectrons went up $400, i'd laugh at those people too. But some need it I guess. I just tune my Kiehin for free and jet it myself for free and it rides like a champ
@@Madtigertv the smart carb is 1k, the lectron is 600, you can say that but atleast every other bike has one or the other, and then the rest have 100$ JD jet kit in them
Another great informative video. I have a 2021 300 Tpi, last couple of rides I have noticed the motor bogging on wide open throttle in the power band. Feels like the choke is on (on an old bike) anyone had any issues? No other running issues, stock bike.
That sounds like an issue with the crankcase pressure sensor. Check that the tube which goes from the rear of the cylinder and brass fitting are both clear internally. if that doesn't fix the issue then the pressure sensor has probably gone bad, or you might have a leak. I've made a few videos about the crankcase pressure sensor so please check them out if interested. This one is a good summary: ruclips.net/video/P1IXInpL-P0/видео.html
@@TokyoOffroad Not yet. He had to go out of town for work and didn't have time. I sense that he is in no hurry and he is bummed that he paid $12k and it seized not even under full throttle. He claims to have done nothing to cause it. I;ll return & update. The fact that KTM abandoned the system after 2 model years is telling.
I’ve heard of quite a few cases where KTM decided to cover the part cost. It’s unfortunate that they would help you with such low hours on the bike :-(
@@TokyoOffroad I think they have helped in some cases but in my case they said that it was how I'd washed it that caused the bearing to corrode and collapse. I'm a professionally trained and qualified engineer as you are, and I disagreed with their assessment, but nothing I could do. Luckily my dealership are a great bunch and minimised the expense for me the best they could. In no way does it detract from the fact that when running and problem free, the 300 Exc Tpi is the best in class in my opinion.
Same for mine, first it was run it out of oil then changed there story to used the wrong oil. Think i would have learned from my last KTM with the dash and seat.
The TPI bikes are trash. I had one, i lived with it, got to know it, and thank god I sold it before it ruined my wallet. Back on a YZ250x, couldn't be happier. To anyone reading my comment, do not buy a tpu, get an older carb ktm or a newer sx. The TPI is junk.
Sounds tasty! But KTM dirt bikes are made in Austria with 2T pistons supplied by Italian suppliers (Vertex is the main one). As you may have read in the press recently, some of the KTM road bike are are manufactured in China (and India), but this has not affected the dirt bike range. The only exception to this is a small number of dirt bikes sold locally in China which are assembled from kits locally in China (using the same parts as bikes manufactured in Austria). This bikes would not be sold into other country markets though.
@@TokyoOffroad Ok. I appreciate what you are saying, but I've seen a lot of complaints online about Kymco pistons crumbling with low hours. As far as I'm aware it's post 2022 KTM 2 strokes. Do you have any knowledge of this?
@@Paul-gu2lv Kymco is a Taiwanese company and they supply KTM with some of the cylinders for dirt bikes. The other 2 stroke cylinders is Elko. AFAIK Kymco do not supply pistons to KTM.
@@TokyoOffroad Yeah, I know what Kymco is. They make great engines for scooters and such, but I guess not strong enough for high compression and performance. Anyway I don't have personal experience. It's just what I saw online.
I did. I currently have a 2024 KTM 300 TBI EXC with oil injection deleted and running premix: 2024 KTM 300 EXC TBI- Oil Injection Delete ruclips.net/video/f4vbqygAFkk/видео.html
@@TokyoOffroad Right on. There's a reason ktm stopped using tpi and oil injection. I'm a professional motorcycle technician and have seen so many blown up tpi bikes.
@@mikecronan550 - I do know some people value the convenience of oil injection, which is probably one of the reasons KTM left it on the 2024 XC-W & EXC models. The other reason of course is reduced emissions. Personally I'm not a fan of 2t oil injection and prefer the simplicity, performance and reliability of using premix. TBI thankfully makes the oil injection system delete easy as unlike TPI injection relocation is not required.
Personally I've only used Motorex Crosspower 2T. It's widely available in Japan and price is similar to other brands so haven't been motivated to try anything else.
In order to estimate the engine temp, it is good to know that the normal human threshold of pain temperature is about 140F, so when it is uncomfortable to touch the radiator or cylinder bare-handed, that component will be close to 140F.
Great information as always. Recently ran the oil pump test on my 21 GasGas EC300 and got the same results. Curious, when doing a normal priming cycle with the oil line connected, apparently if there are no bubbles, the pump will not run (as seen in another video). Obviously don't want to dump a bunch of oil into the throttle body, but what is the ECU using to prevent excess oil or stopping the pump if prime is not necessary? Thoughts anyone?
@@ccenduro it could mean a cracked fuel filter or a loose clamp, there is also a pressure release valve but i'm not sure it would release bubbles, fill the tank up above half a tank and check where are they coming from..

Be sure you are running much more oil if you have a tbi set up. The fuel washes out oil from the bottom end which happens much less on the tpi set up.
When I had this bike I was using a GET ECU, which I understand was mapped to inject more oil than the stock TPI, for use with the GET injector relocation kit which I'd also fitted.
@TokyoOffroad I did hear you mention swapping over but I think it's an important note for riders with a tbi set up. Also great video.
Love your videos, are any of these issues alleviated by TBI instead of TPI?
With TBI the engine will tend to run cooler compared to TPI as the fuel passes through the crankcases. Also TBI allows you to run premix which I consider more reliable than oil injection.
In our ride group 4 out of 10 TPI bikes have seized in the last 6 months. One had less than 40 hours. None of us race or abuse our machines. None of us received any help or compensation from the dealer or manufacturer. The typical out of pocket repair cost at the dealership for this failure is $2000-$2400. I believe that cold weather operation is a major factor in these premature failures. Unlike snowmobiles, the oil tank is not enclosed or heated. All the failures indicated seizure on the intake ( cold) side of the piston. This is the side that receives the oil injection. Perhaps using snowmobile 2T oil during cold season is a good idea.
I also question the frequent piston replacement suggestions. We have inspected a handful of pistons at 250-300 service hours of trail riding use and found them within spec. One outlier has seen 430 hours and still has good compression and doesn’t smoke. As I recall in your previous video that your own piston looked very serviceable at 150 hours or so. For me a significant drop in compression would indicated replacement time more than a set number of hours. Careful measurement of ring gap and cylinder taper upon disassembly would quantify actual wear. Old habits die hard. There have been significant improvements in metallurgy and production tolerances over the past few decades.
Thanks for your video series. You bring an engineer’s perspective to educate and inform the public, a valued perspective.
@@ccenduro I live in Washington State, USA very near the Canadian border. We ride in the snow 3 months of the year here.
That’s interesting Garth - I’m in Utah and ride it quite cold weather throughout the winter as well. Beyond snowmobile oil I wonder if there is something else that we could do to protect the motor. I had a thermostat delete but put it back on as my bike would never go about 120 degrees
@@joshhancey3810 In my experience the TPI bikes definitely run cold. My TrailTech radiator fan assembly has a digital gauge. It was common to see the coolant temp drop below 100 degrees Fahrenheit on downhill runs. The bike would act noticeably cold too. Upon disassembly the seized bikes all had oil present, especially around the reed block. I speculate that these motors and cooling systems were not properly developed for cold weather operation. Oil will not lubricate properly at low temperatures and high loads if it has trouble getting past the reed block to the piston and cylinder. All our seizures have been on the cold side of the piston ( intake side). Jeff Slavens has a good video about this. He has fitted multiple temp sensors and also reports cold coolant temps. Jeff recommends blocking off one radiator for cold weather operation. He certainly knows more than me about this subject.
"Always run the engine warm at low speed" This hurts my brain
Top vidio,explains really well,I will be doing a piston change on my tpi 300 2019 and I will follow he vidio to the latter .👍
I blip my throttle during warm up. It helps seat the piston rings
Number one place I get a good Information
What would happen if the dongo for the oil test was just left plugged in?
Great video, very informative
Thanks! Pleased to hear that you found it useful
70+ hrs on my '22 250xc not a single hiccup
To clean the oil pump without disassembling it, I thought about putting degreaser or brake cleaner in the oil tank and running several cycles like that. Afterward, I would put oil back in the tank and run more cycles, this time with oil, and then reconnect the pump. What do you think? Has anyone already tried something like this? Should i give a try?
I do not have any experience in cleaning these oil pumps and do not know the internal construction, or type of seals used so it's difficult for me to comment on whether doing what you're proposing is safe, or not. If your oil pump has a good number of hours on it and you're concerned about it's performance, my recommendation is to replace it with a new one.
My ‘20 TX300i put out 10ml oil in 60 seconds (short pulses). I haven’t seen anyone reporting this much output (usually around 6ml). Thoughts? I did have the dealer update the map summer ‘22
Maybe the updated map injects more oil during the priming sequence (pulse length might be different). Now you have a reference you can monitor it over time. A significant decrease from your reference would typically indicate that the oil pump needs replacing...
Excellent advise!
Great Video! All the videos are helping me so much with getting to know my 2022 Husky te300i. I just ran 3 oil pump sequences attempting to clear a bubble in my hose.. turns out I should have been working in a better lit shop as it was just a dirt spot on the backside of the hose haha! Would all of that oil just dumped into my throttle body? Should I be disassembling and cleaning prior to starting the bike? Thanks
Malfunction indicator lamp. Error P0650
what should i check?
My sons 2020 husky150i seized after 9 hours. The dealer has had the bike for over a month and no help in site. Parts on back order. Husky/KTM has not said whether they will help or not. Fingers crossed.
I've just ticked over 35 hrs on my '22 250 TPI bike and I just used the 1st liter of Oil... It worries me that Im running with too little oil. I have understanding that the bike auto regulates itself but how can I be sure?
Ive heard that when bike has no oil engine will shut off automatically
Lil ant riding the gnar (top pipe mount) at 5:06 !
Is this the standard for all KTM 300 XCWs? I have a 2019 KTM 300 XCW TPI and it is very low 1.1ml. I just purchased this bike used and I am checking it out.
Mark, excellent video as always. What brand of water proof grease do you use for the rim of the oil filter and what do you use to clean the filter when it’s time to do so.
I use BelRay Waterproof grease for the air filter lip. To clean air filters I first use kerosene, let air dry, then use Oxiclean in hot water. This gets them really clean.
Thank you! Also how do you get the internal area around the cylinder head and wire looms and cables so clean. I use simple green but there is still a brown dirt residue. Short of taking a damp rag and rubbing all the interanal area down I don’t know how guys keep that area so clean. Is there a foam or special way to do it. I never pressure wash so I’m at a loss. Any suggestion is appreciated.
1% premix in the tank as a preventative measure is my cheap insurance.
Great video. Please can you confirm the following. Must you first hold the throttle wide open before connecting the dongle to prime the oil pump or must you connect the oil pipe to the measuring container, connect the wake-up dongle and then open the throttle for 5 seconds and then the pump will activate and run a cycle.
Pleased that you like the video. To start the oil pump priming sequence you must first hold the throttle wide open, then plug in the wake up dongle, wait at least 5 seconds, release the throttle and the sequence should start.
@@TokyoOffroad Thanks
How to drain the side oil? And replace it with a new one ? Please explain thank you
Are you asking about draining the 2-stroke oil from the tank and how to clean/replace the oil screen? It's covered in the KTM Repair Manual in the Lubrication Section. The method is to remove the throttle body, remove the oil pump, drain oil from the tank, remove the rubber boot on the bottom of the oil tank and the oil screen will come out of the bottom of the tank.
@@TokyoOffroad Thanks very much
My husqvarna te 250i 2018 eu is giving me 0,9-1mm of oil x cycle (low-fast, 30 seconds)
How important is it to clean the oil screen? I have 230 hours on my 2020 and I am on my second oil pump. I have neglected to clean the oil screen when installing the new oil pump(s). thanks Brian
Got a 2022 TE300 I , want to wake up my ECU for oil priming test , any idea of bridging plug (EURO 5 ) at connector without buying wake up plug , At the moment Husqvarna are out of stock down under
My ktm exc 300 2022 oil pump not woorking, i change with new one and still not working… whats thats problem, i’m check fuse and relay all goods
Who have some experience in this case, waht it’s the problem thanks
Did you find the issue. It must be an electrical issue. Check the wiring and connector. If the oil pump isn't working you should see a blink code on the dash display
The pump is Mikuni ESOP-04. Has anyone found where to source it - apart from the ridiculously expensive OEM pump from the dealership? It must be installed in a number of other engines...
I'm curious as well
Is there anything else I need to do when getting the old ECU in there? I swapped back (unknown food ECU) and I don’t have a measuring tube, but it’s not looking good lol
No, there’s nothing special you need to do when swapping ECUs. On my 2021 I swapped between the GET and stock ECU with no problems.
The best thing to do is like I did sell that TPI bike and wait till the throttle body comes out 2023 and go on with your life.... Every hard Enduro race of the professionals they stripped that stuff off of their bike and put a carburetor on blocking off the electronics that is a fact none of those hard Enduro championship races are done with TPI that's why they're getting rid of it... it failed way too many times
Anyone tried this with the GET ECU for a set length of time?? I just wanted to compare to what mine is pumping. I believe mine pumped approx 2.75 mL of oil after 2 min of holding the throttle fully open with the dongle plugged in.
I have a 2019 te250i with the GET ECU, so what is the recommended testing with the get then? What specif time should I be holding the throttle down for and how much oil should I be getting?
my 2020 te300i runs for 30 sec and yeilds 2 ml. Thoughts on this?
Another great one!
Why am so nervous to pull the trigger on a TPI? Case of over researching possibly. I just don’t want to be stuck looking at bike that’s seized, maybe I should just go 4t route?
Depends what riding you're doing. I much prefer 2-strokes for the terrain I ride, but if you ride more open, higher speed a 4-stroke might be a better choice. If you like the TPI then go ahead and buy one. Maintenance is easy and cheap to perform yourself.
I just did measurement in 7degrees warm garage ( i dont know how much that will affect the result). I got 5.0-5.9ml, and my bike is EXC 250 TPI 2020, with 300EXC map(gives bit more torque). So i dont know is that good or bad and should i have something different than 6.3ml since bike is 250cc?
Dear riders, i have 2021 250 Exc Tpi. I tried to make the oil priming with the wake-up connector bought from the dealer (the red and black one) The oil pump did not test/work as in video. I tried more than 40 times with different time intervals 4-7-9-12.....25 seconds. I have the standart ECU. I watched all the videos and read the manual, Did exactly the same.
Do you have same oil pump problem? If yes how did you solve?
If your bike is a 2021 TPI with stock ECU it should prime in exactly the same way as shown in the video (set number of pump cycles every time). I suggest you discuss with you KTM dealer.
recently bought the 2022 model, 26h in and i had a damaged cylinder head and piston. bike was not used in motorsports, only for casual riding and some soft enduro. any tips on what should i do or check? i tried to contact ktm but they said i only have 1 month warranty after purchase and 1 1/2 months passed since i purchased so my warranty is currently expired.
Chances are that the damage happened during cold start, these tpi bikes can not be revved at all until hot and they take several minutes at idle to warm up depending on outside temp. From what i've seen the people who are meticulous about warm up do not have any issues. Not your fault as there wasn't enough awareness about this to owners until recently.
As long as there's no air in the line it should be, right?
Yes, if there's no air bubbles in the line it's fine...
@@TokyoOffroad thanks for replying
Very informative ,great site ...But fuel pumps ,oil pumps ,crankcase pressure sensors etc etc fuel injection has no place in enduro bikes .Great idea on informing ktm on the problems you may have encountered but that won't get your bike back to your truck. And the bullshit KTM had to introduce TPI to pass Euro emissions ...Beta,TM,reiju all seem to have met Euro standards without TPI. It seems KTM introduces technology that isn't properly proven akin to VW .I'll take Carb , Kickstart and KYB suspension anyday and make it back to my truck every time.Anyway great site ,I'll continue to watch irrespective of the KTM content
Same shit is in all other hard offroading machines 🤷♂️
And beta oil pumps fail way more then KTM, they are basically known for it lol
@@samuelyeet6006 The sherco,TM Beta and Reiju are all carbed or offer a carbed version in their premium bikes.Yor statement is totally incorrect you plonka
@@samuelyeet6006 Again ,the Beta is premix in their racing premium models
@@ktmkaos by other hard offroading machines I meant things with more then 2 wheels lol yes carbed, but they still have oil injectors... it doesnt have to be fuel injected to be oil Injected lol you "plonka"
Mine had a seize around 80hrs, didn't realise till I took off the pipe off to clean, looked into the cylinder saw the intake side of the cylinder was badly scored
That's too bad. Intake side scoring could be due to dirt ingestion. What did you do?
@@TokyoOffroad got the bore honed it was barely saveable, new piston, also put a two stroke performance tune on it for extra oiling. Bike is a 2018.
I did the oil pump priming sequence 3.1ml in 30 seconds, yours was over 6ml was that a 1 minute test?
@@Huda88754 his test ran for about 33s in this video
@@Huda88754 - I just checked the raw video and the KTM stock 2021 ECU oil priming sequence lasted exactly 1 minute.
Chances are fairly low ?? There were 3 people in my group of riders that experienced the engine sized seems like a lot for one location
Wow! I personally don’t know anyone who has experienced a TPI seizure, my dealer told me that the actual seize rate is in the low single digits…
thanks so much!!!
Hi! I did the test and I am getting 6.3ml , is it ok to keep running the same oil pump? At what lower amount should I change it?
Yes, that's the same as I measured so should be fine to continue using the same oil pump. I would say if the volume drops 10% (below 5.7ml) then it would be a good idea to change the pump. Note that this is not something specified by KTM...
excellent thx
Ant spotting at 5:06
How much oil did the Get ecu dispense?
With a GET it will cycle the oil pump as long as you keep the throttle open. As such you need to decide on a time period to do your measurement and keep the throttle open all the time. I prefer the stock ECU priming sequence method for this test, although the GET method is great for just clearing out air bubbles from the hoses after you’ve had it disassembled for maintenance work and means that your throttle body doesn’t get swamped internally with oil.
Anyone tried this with the GET ECU for a set length of time?? I just wanted to compare to what mine is pumping. I believe mine pumped approx 2.75 mL of oil after 2 min of holding the throttle fully open with the dongle plugged in.
I unfortunately bought one of these pieces of crap. 2022 KTM 300 XC TPI.
The dealers cannot fix it and KTM will not cover anything under warranty even though it ran like shit from the 1st day.
I will never buy a KTM again.
I was warned I would regret it.

That's a 2021? What forks are those?
XPLOR forks, but I'm using Dingo Racing fork guards on the tubes: dingoracingproducts.com/
@@TokyoOffroad do you prefer the Xplor forks? I just thought all 20 and up had AER
@@samuelyeet6006 No, the 2017~2021 all KTM EXC and XC-W models are fitted stock with XPLOR forks. The XC and SX models are fitted with AER. Stock the XPLOR forks work well at low speed, but tend to blow through the travel too quickly and don't feel stable at speed. Over the years the valving in XPLOR fork valving has changed with some improvement (2017 was way too soft, 2021 is much better), but I have modified my bikes...
$12g bike that needs $2g more of engine hop up's and its very own video on "how not to seize"... Yea i'll stick with my Sherco 2t. Best bike out of the box.
Agreed!! Lol
They don't actually need anything. Half the people are just idiots and the other half listen to idiots. I've beat the piss outta my TPI and over 120 hard hours.....only issue in all that time was a failed crank case pressure sensor ($45). It's time for a piston but it still runs flawless!
Bro they dont need anything, people just want more power, you act like carb people dont drop 1k on a lectron or smart carb, another 20 hours tuning the bike, and another 1k in other performance parts, it's the same for both of them
I had No idea Lectrons went up $400, i'd laugh at those people too. But some need it I guess. I just tune my Kiehin for free and jet it myself for free and it rides like a champ
@@Madtigertv the smart carb is 1k, the lectron is 600, you can say that but atleast every other bike has one or the other, and then the rest have 100$ JD jet kit in them
Another great informative video.
I have a 2021 300 Tpi, last couple of rides I have noticed the motor bogging on wide open throttle in the power band. Feels like the choke is on (on an old bike) anyone had any issues? No other running issues, stock bike.
That sounds like an issue with the crankcase pressure sensor. Check that the tube which goes from the rear of the cylinder and brass fitting are both clear internally. if that doesn't fix the issue then the pressure sensor has probably gone bad, or you might have a leak. I've made a few videos about the crankcase pressure sensor so please check them out if interested. This one is a good summary: ruclips.net/video/P1IXInpL-P0/видео.html
My buddy just seized his 300 on Sunday.
Sorry to hear that. Do you know the cause?
@@TokyoOffroad Not yet. He had to go out of town for work and didn't have time. I sense that he is in no hurry and he is bummed that he paid $12k and it seized not even under full throttle. He claims to have done nothing to cause it. I;ll return & update. The fact that KTM abandoned the system after 2 model years is telling.
The best thing I don’t is to run it free off 2stroke runs loads better
KTM do not help out with repair costs for part failure. I had a main bearing collapse at 6.5 Hours on my 2019 300 EXC TPI and they refused.
I’ve heard of quite a few cases where KTM decided to cover the part cost. It’s unfortunate that they would help you with such low hours on the bike :-(
@@TokyoOffroad I think they have helped in some cases but in my case they said that it was how I'd washed it that caused the bearing to corrode and collapse. I'm a professionally trained and qualified engineer as you are, and I disagreed with their assessment, but nothing I could do. Luckily my dealership are a great bunch and minimised the expense for me the best they could. In no way does it detract from the fact that when running and problem free, the 300 Exc Tpi is the best in class in my opinion.
Same for mine, first it was run it out of oil then changed there story to used the wrong oil. Think i would have learned from my last KTM with the dash and seat.
TPI.....What a pain in the ass.
Carb it and problem fixed
Just put a pwk on it and problem solved
I think of this every time something goes wrong, setting it on fire is another option.
Anyone else see that ant and think it was on their screen? haha
Yes me, when I was editing the video! LOL
sounds like ignorant people. Any experienced rider should know about cold seizures. Good tips for the ones who don't know any better
The TPI bikes are trash. I had one, i lived with it, got to know it, and thank god I sold it before it ruined my wallet. Back on a YZ250x, couldn't be happier. To anyone reading my comment, do not buy a tpu, get an older carb ktm or a newer sx. The TPI is junk.

I heard the Chinese pistons are made out of cheese.
Sounds tasty! But KTM dirt bikes are made in Austria with 2T pistons supplied by Italian suppliers (Vertex is the main one). As you may have read in the press recently, some of the KTM road bike are are manufactured in China (and India), but this has not affected the dirt bike range. The only exception to this is a small number of dirt bikes sold locally in China which are assembled from kits locally in China (using the same parts as bikes manufactured in Austria). This bikes would not be sold into other country markets though.
@@TokyoOffroad Ok. I appreciate what you are saying, but I've seen a lot of complaints online about Kymco pistons crumbling with low hours. As far as I'm aware it's post 2022 KTM 2 strokes. Do you have any knowledge of this?
@@Paul-gu2lv Kymco is a Taiwanese company and they supply KTM with some of the cylinders for dirt bikes. The other 2 stroke cylinders is Elko. AFAIK Kymco do not supply pistons to KTM.
@@TokyoOffroad Yeah, I know what Kymco is. They make great engines for scooters and such, but I guess not strong enough for high compression and performance. Anyway I don't have personal experience. It's just what I saw online.
Best way to prevent is to stay far away from ktm
Dump the TPI and buy a TBI or carbureted bike with premix. If it ain't smoking it ain't getting lubed.
I did. I currently have a 2024 KTM 300 TBI EXC with oil injection deleted and running premix: 2024 KTM 300 EXC TBI- Oil Injection Delete
ruclips.net/video/f4vbqygAFkk/видео.html
@@TokyoOffroad Right on. There's a reason ktm stopped using tpi and oil injection. I'm a professional motorcycle technician and have seen so many blown up tpi bikes.
@@mikecronan550 - I do know some people value the convenience of oil injection, which is probably one of the reasons KTM left it on the 2024 XC-W & EXC models. The other reason of course is reduced emissions. Personally I'm not a fan of 2t oil injection and prefer the simplicity, performance and reliability of using premix. TBI thankfully makes the oil injection system delete easy as unlike TPI injection relocation is not required.
Any other oil recommendations? Hard to get the motorex oil
Personally I've only used Motorex Crosspower 2T. It's widely available in Japan and price is similar to other brands so haven't been motivated to try anything else.
12000 bike and the failed rate is low. Lol
Good tips dude. While there probably are some bikes that seize from defects, the majority of the ones you see are PROBABLY owner failure.
What an excellent channel.
In order to estimate the engine temp, it is good to know that the normal human threshold of pain temperature is about 140F, so when it is uncomfortable to touch the radiator or cylinder bare-handed, that component will be close to 140F.
True . This is fairly accurate.
All this is why I'm sticking with my carb 2016.
My yz125 dosent have a thermostat so I made some cardboard cutouts that I can slide in between the rads and rad guards for riding in cold temps
To complicated I'm keeping my old bike.
Great information as always. Recently ran the oil pump test on my 21 GasGas EC300 and got the same results. Curious, when doing a normal priming cycle with the oil line connected, apparently if there are no bubbles, the pump will not run (as seen in another video). Obviously don't want to dump a bunch of oil into the throttle body, but what is the ECU using to prevent excess oil or stopping the pump if prime is not necessary? Thoughts anyone?
Great info.
Who else saw the ant @5:05 ?
Me! LOL :-)
My 22 300 has done over 100km and 33 hours, no dramas at all.
I did get the extreme map put on, no damage to the bore or piston as far as I can see
50 hours and 1000 km plus, still no issues at all.
Also check fuel pressure or bubbles in the tank while running the engine
Yes, I did make a video about TPI fuel pressure testing. It’s another good test to perform periodically…
@@ccenduro it could mean a cracked fuel filter or a loose clamp, there is also a pressure release valve but i'm not sure it would release bubbles, fill the tank up above half a tank and check where are they coming from..
