The Unknown Truth Behind KTM's TPI!

[@KiwiYoshi1100]

Uniflow is a friend of mine. He is a very clever guy who comes up with all sorts of amazing engineering ideas from the TPI mention in this to making and selling engine/propeller reduction gearboxes for aircraft. A very decent and honest man who has my (and many others) utmost respect.

[@guidohl9444]

Good on you for publishing this video. Classic case of big business disregarding the true creators. Neil is an engineering wonder of the world and the very least ktm could do is acknowledge his talent. And the gall to try and patent it as theirs for more cash! Bastards. Lucky TM were there to assist.

[@pauln6803]

It's not as predatory as you might think. It sounds silly but so patent applications are just to stop another company/individual from doing so first. KTM might well have known their application would be challenged, but at least that ensures they get to use the design licence free.

[@jacobac42]

I'm kind of surprised that the process to develop the KTM TPI was such a large challenge. Might be a daft comment, but at the same time we had EFI in two stroke snowmobiles since around 1991 with the Polaris Indy 500 EFI. It used a throttle body fuel injection system with a crankcase inducted oil pump. Worked pretty well and was reliable, along with being relatively simple, especially considering the regular Indy 5 used a carb engine that was almost identical apart from the intake. Just seems like a very complicated way of doing things compared to other powersports applications that are quite similar.

[@howelllunn7989]

Or the development of two-stroke outboard engines, it's been happening since the '90's

[@tjroelsma]

It could be that the problem lies in squeezing the most power out of the engine. Snowmobile engines aren't tuned for the highest power, they're tuned for reliability. In the video it was already explained that heat is a problem and the heat rises significantly when you want to squeeze more power out of an engine.

[@thebros-br3to]

​@@tjroelsma Snowmobiles are manufactured 100% with high horsepower in mind. They went efi because they are making more power and it was harder to tune. Sleds see huge elevation and temperature changes drastically in one ride and that was what was causing reliability issues because of tuning restriction on carbs. If it wasn't about hp and just reliability they wouldn't be manufacturing these sleds with turbos.

[@tjroelsma]

@@thebros-br3to There's a difference between an engine being tuned for high horsepower and maximum horsepower. Altitude is always a problem with carbs, so they went with EFI, not to raise the amount of horsepower, but to avoid the drop of horsepower. Snowmobiles also use a CVT and for a CVT you don't want peak horsepower, you want optimum torque in the range where the CVT works the best, which is between 50-70% of WOT. Everything above that does increase the speed, but drops the torque, which is why snowmobiles can effectively pull heavy sleds, because in that midrange the engine delivers maximum torque to the CVT.

[@user-pp5or5og4k]

Kawasaki and Sea-Doo also had this technology in their personal watercraft 20 years ago

[@BricoleurTV]

14:32 you can’t say it was the worlds first. Outboard 2-strokes with fuel injection has been around since the 90’s. Starting with OMC (Johnsson/Evinrude at the time) then followed by Suzuki and the rest… Still Evinrude sells big 2-strokes while almost all other manufacturers has switched to 4-strokes on their bigger engines. Thanks for yet another great history-lesson though 👍

[@gasdive]

Fun fact KTM also stole TBI. Yamaha used to make snowmobiles that used more or less the same technology as TBI. However, Yamaha's patent expired and so KTM could use it. greetings from Austria👋

[@Anatoli50]

Great analysis @Krankit, but no mention of TPI’s Achilles heel: cold seizure. Here in the Pacific Northwest of the USA we ride year round. Winter temperatures are frequently around freezing. We had 6 out of 12 new TPI bike seize in a 4 month period. I ride over 200 hours a year and had not seized a piston in over 50 years. I eventually traced the design fault to the oil and fuel injector mounting positions. At cold startup, the mix oil is pumped into the intake tract upstream from the reed block. This cold thick oil coagulates on the reed block, not penetrating and thus not properly oiling the cold piston and cylinder. The TBI system places one fuel injector upstream of the reed block. This fuel injector provides the gasoline to dissolve the cold injector oil allowing penetration of the reed block and into the engine. We have yet to experience a cold seizure with TBI. I currently have 230 hours on my 2024 TE 300 TBI bike and am still running the original piston without issue. Both TBI and TPI bikes require frequent replacement of the Crankcase Pressure Sensor ( CPS) although the sensor on the TBI bikes has been upgraded and is easier to service. If you are running a TPI bike in cold weather consider running snowmobile premix oil and not loading the motor until the coolant temperature is hot.

Being an early adopter of TBI with a 24' 300 EXC , I really hope this doesn't come back to bite me in the rear... Hopefully they have the tech figured out and we dont suffer any early adopter issues. Great video as always.

[@suzuki06g]

Interesting video!! I have to admit that I'm in the US and I bought a 2018 250xcw TPI (the first injected KTM). On my first ride I thought that I made a major mistake, in simple terms it was slow. BUT, after doing what's known as the "idle screw mod", plus a medium compression head and ECU tune from TSP, it finally ran like it should. From there I thought that it was perfect.

[@human1513]

Outboard motors like Mercury had injected 2 strokes almost 50 years ago. I converted a 300 TPI to TBI and now it is reliable. I did it just before KTM started to change the 300 XC 's to TBI from TPI. The KTM TPI 300's had approx. 10+ ECU maps over the years. And the throttle body air bypass screw was set differently on every year.

[@OtisFlint]

21 & 22 were reliable

[@human1513]

@@OtisFlint Big wrong!! 🤣🤣🤣🤣 I have a 2022 KTM 300 XC TPI it was a huge piece of crap. I know of many 2022's around the world that would seize. The largest dealer in my country had mine multiple times and could not determine why it never had power and would cut in and out when riding it. It cut out once so bad when they were test riding it that is flipped over backwards right in front of me. It seized at 7.4 hours. KTM replaced the crankshaft, piston & cylinder. I paid the labor. It seized at 7.4 hours again. Less than 6 minutes on it. KTM replaced it with a complete new crate motor and a new oil pump. KTM covered it all 100%. Then it ran like a different bike. After 2 hours I turned it into a TBI (before the 2023's came out with TBI) and to premix. It has been good now. I have been riding bikes for 40+ years, am a licenced mechanic, a control and instrumentation Engineering Tech and a mechanic tech. I could not find the problem. I do not have all the diagnostic tools the dealership has. I never heard from anyone what the issue(s) where that my or any KTM was having. The dealer told me they had more bikes with poor power also.

Awesome video. My feelings were that ktm were reposnding to years of posts on bulletin boards in mid '00's asking for injected 2 stokes that would make them feel like 4 strokes. Ktm wanted to be first in market but had the fallback explanation of emissions if performance was critisized. Ktm struggled with any new tech like when they tried slipper pistons and split crankcase oiling (on 4 strokes). It was never going to go smoothly.

What a brilliant video, I thought I recognised the trails and then realised it was Bulgaria where I now live. I have worked for KTM in the UK and they have invented very little. Just take a look at the cylinder heads on the RFS engine, now take a look at the early Husqvarna, later to become the Husaburg, maybe that is why they had to buy Husaburg? I have been riding bikes for over sixty years and fuel inject will never be as good as a carb. The first version of KTM's inject in their road bikes was (as delivered) dangerous. My last point is why does it even need to be on performance machines? Their emission's are not even calculable in world terms. Just smoke and mirrors, how much oil and how many rebuilds does the latest KTM 4 strokes need in a year, if you are to believe their own manual? Lets get all the trucks and aircraft converted to electric first. Do things that make a real difference.

From my view, TBI is step back in fuel injection technology. With TPI, there is virtually no gasoline in the cranckcase, which is good for bearings. And there is much more precise controlling amount of fuel that goes into combustion chamber. With TBI, if you close throttle, there still is some fuel left behind in the crankcase. I suspect the cost savings is he main reason why KTM switched to TBI from well established TPI. Now they don't need special cylinder with machined holes for injectors.

[@vladimirsamardzic963]

How you going to regulate temperature in cranckase and pressure without oil or gasoline that's whay they need transfer ports!!!🎯

Yamaha had direct injected two stroke outboards as did Tohatsu and Mercury in the 2000s but Evinrude were the first in the mid 90s although it was a troubled system.

There's a common belief that fuel injection on a 2 Stroke is difficult, but it's not at all. The problem always was that everyone wanted direct injection, which is more difficult indeed. TPI (Throttle Port Injection) was the closest to direct injection, that's why they went that route. I never understood why simply replacing the carburetor with a throttle body was apparently not an option, especially since it allows a cleaner combustion. Now KTM did just that and it works miles better than the TPI. Overcomplicating things is often the biggest problem.

[@leftyeh6495]

Brp has the e-tec direct injection motors in a ton of things. Why nobody will license stuff and we keep wasting resources and raising unit costs to reinvent the same technology over and over is astounding.

[@ChrisHoffman-ed7pv]

For ten + years Rotax has had direct injection on there snowmobile engines, with great success. The technology is there. With direct injection there's 0 raw fuel in the exhaust, because fuel is injected into the cylinder after the piston has closed the exhaust port. Im sure Rotax has paton on it because neither Arctic cat or Polaris hace direct injection. But in time it will expire and hopefully other two stroke manufacturers will adopt this technology

[@zackk695]

KTM needs to repair all bikes sold with this and stand behind their bikes. I support KTM because of having 2 strokes but KTM needs to be the leader in making all pro racing fair. A bike that races should have to race its class. Example of it’s a 250 2 or 4 stroke then they race each other. This will bring back the 2 strokes because we know the 4 strokes will not being able to match up to the 2 strokes. KTM needs to get the AMA ruling changed back to the way it was with a 125 & 250 pro class and maybe even 500’s. This is where the sport will become huge. People can’t see these bikes ever so that’s a big issue. They need to get people to the local tracks to see the bikes. We need a ranking system for amateurs in every state just like BMX. To get people to t actually see the bikes up close they better get them riding close to communities so build practice tracks that are a calmer version of a huge race track. This needs to be in all parts of all cities which have middle class communities. This will allow people to drive by and see the bikes out riding. They also need new riders to be given lessons as well as be able to rent used bikes to ride till they can afford a bike. The 2 stroke bike cost cannot exceed $6,000. To do this they may need to speak with leaders such as Elon Musk and others
