EFI vs Carburetor 2 Stroke KTM Dirt Bike | What should you buy in 2018 or 2019?

Nothing like spending $140-$160 every 80 hours on an oil pump my goodness dirt bikes were simpler at one time now we are making them more and more complex in the name of smooth as butter, and the off chance your oil pump takes a dump and the engine locks up that is a horrible anxiety inducing design for an $11k bike i would of expected more fail safes not fail enducing features leaving me to eat the cost on a rebuild. Sucks not having options in the future i can see why the bike industries are hurting so much. Keep It Simple Stupid.

I’m in the market for husky 250 or300 is tbi mixin gas and no oil pump ?

There is very little difference in fuel efficiency however the amount of oil a tpi uses is less than a quarter of the carburetors!

I’ve got 300x tpi my opinion it’s way better than the carbureted

Yesterday I tried riding the ktm exc 250tpi 2020, I can't believe how much weaker it is than my sx 250 2011, the exc is great for its purpose, but it's not a fun bike for me

Wonder why they have different forks

If you are a moto dad with a herd of small carbed bikes, get yourself an EFI. On my first one. In 3 years havent touched or adjusted a thing and after 100 hours its as barky as the first day.

Because I ride with major elevation changes, EFI has been the best since the invention of the wheel! Even my old yz250 has the closest thing, Lectron Carb, that thing once I had the lean/Rich perfect, that Bike has never been better.

This video is a few years old, since then the TPI bikes have shown to be very problematic. The TPI system needs a ton of sensors, (crank pressure, ambient pressure, etc...) to work correctly and there are many reports of problems. Stick with a carb for 2t, or go 4t if you want EFI. Yes a carb requires tinkering, but at least I know that when i have fuel/air problems its the carb and not of a plethora of sensors that you can't diagnose without a trip to the dealer.

What I do is
Carburetor for mx
And tpi for trials

Shout out from Phillipines

Wuts a cheap 2 stroke i can get get?

I've heard they run horribly from the factory lol

Carb is like 8 pounds lighter too

Awsome video man but damn you talk fast lol

you could probably buy a lectron for the price of the tpi, plus ive had a yamaha rt 100, which has a oil reservoir, and it cracked open 2 or 3 times

4-5 years? its 2021 (almost 3 years from the video upload date) and i already cannot get a brand new carburated version anymore (at least in my country), KTM only sale the TPI version for offroad bike, and stop importing the XC version, so if i want to get a brand new carburated 2 stroke offroad bike, the only option is with converting SX bike for offroad, or get the bike from another manufacture like yamaha or sherco.

How can you tell if the oil pump is gonna fail, I got a kx450f it runs nice but I just don’t want to blow my bike up in case it fails.

I feel the same way about injection on 2 strokes as I do insulin pumps for diabetics. You just can't be certain you're getting insulin delivery. Just as you can't be certain you're getting oil delivery. I would rather mix fuel all day long and know the engine is not getting oil starved.

A dumb question!
Is a carburetor engine different from the injected ones ??

Idk a damn thing about carbs. I have a Yz125x and a lectron carb and well it’s fire 🔥

Thanks Kyle! This has been very informative to me.

Wow, you got me thinking. My riding goes from between 3500-4500 feet in the mountains, to less than 100 feet in the valley at the mx track. You think a carburated bike would work for that? I don't want to re-jet every time I go ride moto.

The day they have tunable fuel curve maps available for EFI I'll consider one for a two stroke.

You spend too much time talking just wasted hot air then actually about the difference in the carburetor and the TPI system.

Would a guy buy a 4 stroke if the oil pump wore out in 60 to 80 hours?

Ive seen guys spend 1000 bucks trying to get TPI to run absolutely incredible. Lean spots,etc.

So whats better for the weekend warrior just wants to go tear up trails and have fun ?

Actually tpi bikes don’t mix the oil and gas for you it’s completely separate the oil goes in the crank case and the gas goes in the transfer port and if you’re oil pump fails the bike doesn’t run

Karburator!

In regards to the oil pump, Why would they not simply put a pressure sensor in the oil line that kills the engine with loss of pressure?

Imo TPI is only good for keeping 2 strokes alive in strict emissions places. I'd get a Lectron carb if I were constantly changing elevations

I was looking into buying a 2019 300 xcw brand new but my buddy is selling me a 18 300 for 6k what’s the best idea

Are you in idaho I live up in the treasure valley area and am seeing some familiar spots

I have one EFI sucks

I'm stuck between the Ktm 250xc and the Yamaha yz250 2 strokes. I've seen alot of your videos are on the Ktm dirt bikes.. which one would u guys get?

What carburator did you compared the tpi to in this video? Lectron or keihin?

Kyle i love your videos and awesome dad skills. This is the video where you get into real issues of carb v tpi. My question: how better is tpi over lectron if at all

Keihin + STIC block.

stupid loud music

Judging from all the broken down KTM TPI bikes I've come across in the mountains around here. TPI adds about 100 new points of failure. 2 of them I think maybe KTM was trying to be too neat witth wiring. The bundle leading into the ecm module was just plain too tight and I think the natural flexing in the frame, over time, just wore out the retention clip and pulled the plugs loose just enough to were the motor just wouldn't stay lit.

On a carb, when you crack the throttle from idle there is a surge in air velocity before it settles. the overlap between slow speed and mid range circuits in the carb act a little like an accelerator pump so you get a quick bump a low speed. Put a vcuum metter on it ,,,you can see it happen

4 bangers need no pump or mixing gas

It took 10 min to jet my bike from 90f to 10f.

Get a carburetored bike and put a lectron in it. Way cheaper than efi and you still get the benefit of automated tuning.

On my snowmobiles EFI gets about double the gas mileage which is big for riding all day. And it seemed similar with my 4 stroke 250s. And a always hated taking the carbs off to clean them every year on my quad and bike.(even running ethanol free)

kyle,,can you run elf lms in a 2020 tx300i huski

90 miles from any sort of civilization, I'd MUCH prefer a bike with a carburetor, a kick-starter, and spring forks! Modern bikes, if ANYTHING happens to your battery, you'd better have Bear Grylls SKILLS or you're TOAST!
