Only $10 for all 2024 SX, MX, and SMX series (regularly $30).
Boats, sleds, etc. All more. A typical outboard has 20 more and a sled about 5, so a bike would have about 2.5, all else being equal.
EFI is actually cake to fix..
Anyway.. lots of good posts.

To the guy saying hopefully yamaha will keep up. Yamaha was the first to have a FI 250. It was called a WR250X. They didn't put it on the YZ because they could not afford to loose 3hp compared to the carb on the old style motor. They had to wait for the downdraft design to compensate for the hp lose.
This is all common knowledge, if you are thinking I'm wrong, might want to do a little research.
When the efi yamaha 450 mx quad came out factory suppprted riders took off the efi system and put om carbs.... so did yoshimura suzuki on the LTR450...
I asked brandon sommers when i saw his quad on the line with a fcr on it and he was very tight lipped. Lmao a factory team pulling off a feature theyve invested and endless amount of time and money in and told the public you had to have their bike causd a carb is now antique
The RXL was a full year cycle ahead of the 500 twin in EFI development
RXL '90 LE
'91 production
500 EFI '91 SP
'92 production
Skidaddle said so and he's never wrong. Just ask him.
Come on man. Lets compare to F1 if anything. I got a 1970s vintage 340 oval sled with more power than that.
Regardless, Every sled when you could get both was rated more, and every outboard Merc sells from the high performance race division has 20 HP more with EFI, and sleds do because you can such a large 44-52 Mm throttle body.
They don't claim it on their brochures for nothing.
Looking at a brochure now.
Merc 2.5 Carb 260 HP@7800
Merc 2.5 EFI 280 HP@7800
Merc 2.5 EFI Offshore 280HP@8000
Merc 2.5 EFI Drag SS 300 HP@9000
They don't call them 280s for the hell of it.
Same for the older 2.4's. The EFIs were rated at 20 more. Maybe for all those years they lied.
You could get them, but you had to get it somewhere else.
I guess that would be like a guy in Minneapolis wanting a 800 RMK Pro with a 3 x174 track. He'd have to special order or go to Colorado alot to need one.
I'm programming a EFI turbo setup for a buddy tomorrow.
Or did they not fuel inject the YZ-f because they were developing a completely new engine with FI so there was no point trying to fix an old bike.
I also think people are scared of their old bikes losing value because 2 strokes have made a major leap forward and in 8 years, their 20 year old two stroke won't be competitive the same way it is competitive with today's 2 strokes.
You remember these?
Pit Row
I just noticed alot of posts are gone.
The mother of 2 stroke music is the Mercury 2.4 and 2.5 series race outboards.
2 strokes just work. They never really had problens and it was almost 30 years ago.
KTM or Beta would really have to F up to get it wrong.
Plus being in Austria...KTM could hire some Rotax dudes to help them. Or Suzuki techs or whoever from say Mercury.
It wont be perfect, but it should be 97%.
Even at the pro racing level = stone age.
This is a very good thing.
I killed my truck for an hour last week after powerwashing under the hood.
I knew right away it was the throttle body fly by wire connector.
And....I knew better, and was too lazy to cover it. It's wide open just waiting to get grounded out.
You cant blame the machine when blasting 1500 psi water on electrical shit.
I'ven been on SX250s since 2012, jet my bikes once when they are new for "average" conditions and then run the same thing winter and summer. Sure it'll be a bit lazier at 30 degrees Celsius, but bogging? Never. I take 5 mph turns in 3rd gear and a gentle feathering off the clutch will put it in the meat of the powerband instantly.
As far as smoother power..What many people fail to realize is the versatility these bikes offer. These bikes can be made into a 55HP firebreathing monster that could yank your shoulders out of their sockets, just as easily as they can be made into soft, no-hit Vet bikes.
I'm not saying EFI or DI or Oil injection can't offer any benefits because I don't know anything about that stuff. I'm only saying it will be an incredibly difficult task to make a bike that is SO much better than the current platform that it outweighs all the known cons such as weight, price and complexity.
Fuel injection is superior for nearly every application, IMO. I'd pay extra for it.
