Efi means electrical components that go bad and are expensive as shit to replace.
Everything needs a sensor now. Thats added electronics.
Fuel injectors have extremely small openings for gas to be sprayed in case you didnt know. Oil is at a much higher viscosity than gasolline and will be harder to push through the openings.
Compare your 30 year old whatever to a modern 450 race bike and it will look like shit. The 2 stroke ktms need to meet or exceed the 4 strokes to be viable.

Not going to get into the whole argument over if its good or not. But we have no problem with getting mixed fuel through snowmobile injectors (Polaris and Arctic Cat). One down fall of being DI is the reeds not being lubricated with anything and failing earlier. Hence V-Force and Boyesen making rubber coated cages for EFI sleds.
That is all.
The airbox sensor is 9 dollars...at autozone.
Water temp sensor is 15 dollars....at autozone. All made by Bosch, which is what most OEM use.
You do realize two strokes have been running premix EFI and race outboards still do for the last 30 years.
Oopsie. Explain this extreme cost to me for parts that in 30 years, Ive never had a failure.
Twins fire every up AND down for each stroke and the triples and the firing and injection timing were totally different. The aftermarket figured it out with an aftermarket EPROM chip that took a few minutes to swap.
The best part of that was......the aftermarket chip could compensate for the impending ethanol gas that hit the west in 1995.
For twin owners...Polaris gave owners in Ethanol states a free chip! I got mine with a free tube of dielectric grease and a free grounding strap also.
To be honest...the ethanol chip ran better and was updated mapping.
My sled has a holley to replace the stocker Mikuni, and on my boat I got a Holley 240 GPH EFI pump for a spare and it was about 150 bucks online. I think a stocker was double for the same exact thing.
Remember this....the pump is probably made by whoever makes the throttle body. Get the same GPH and pressure rated pump and you're good.
I dont see how a fuel pump can be 500 bucks when EFI only cost 350-500 more on a sled and a grand on an outboard with 6 injectors and a higher pressure pump (luckily external) and swappable in 5 minutes.
A fuel pump quitting is really rare. The best part of my boats outboards being 32:1 from the factory is shit lasts.
Want to quite your cars noisy fuel pump? Add a couple ounces of 2 stroke to your tank. Boom. Silence.
The vehicle down sensor for my kx was $70 for a used one.
An oem kx450 injector is $105.
This is for a jap bike. It will be more for a ktm.
On EFI you can run premix or with SDI(Depending on if you have a throttle body or crankcase injector you can get away with no oil injection.
IMO true DI is alot riskier, and more prone to problems.
True DI runs double the fuel pressure roughly, or more than a simple EFI or SDI system.
Pit Row
Just like Honda brand spark plugs are just overpriced NGK in a red box that says HONDA BR9....lolz.
However, it will also be smooth, pretty much "show up and ride" anywhere ready and no more guessing for trying to get rid of the bog and what now. The biggest benefit IMO, is the addition of already the counter balanced motor.
probaby the same as his 450F
Beta 300 RR has oil injection. Add EFI and you're 2020 CARB compliant. Like snowmobiles.
The kicker is, 2 strokes are cleaner burning per HP/CC than 4 strokes.
I mean you have 600 2 strokes in the same class as 4 cylinder 1,000 cc 4 strokes. Thats a lot more hydrocarbons being emitted.
And they are damn near smokeless when cold. Thats hard to beat.
Where do you think all this technology comes from?
Race machines do not and will never use the same injectors as a snow mobile or a car or even a street bike.
God i hope youre just a troll
