Two Stroke Comeback - Direct Injection

The coming of direct injected two strokes is just around the corner. When this happens, it will not only produce a cleaner burning two-stroke, it will produce that same instant throttle response with tractability improved. Custom maps, timing etc will all be part of the game. Watch and see two strokes make a comeback like you have never seen. The good part is, you can still rebuild them in an hour for under $200.

:thumbsup:

who will be the first to release one though?

My money is on KTM or Husky. Sherco are in the mix and I have read somewhere that Beta are bringing out a range of 2 smokers soon. Any other players? TM? Gas Gas?

is it possible to have a 2 stoke where u dont have to mix the oil? there for has a sump? so place the injector at the top and just inject when ever necessary

I had a Suzuki 90 in 1972 that had that technology. :thumbsup: Damn I'm getting old.

injected 2 strokes has been around for a while, it has not made any come back by any means, in the snowmobiling world a fuel injected 2 stroke is not that much better then carb'd (i would know) it can also create big costs$$$$,

also with tuning a bike, there is only so much you can do, for timing and fuel delivery, towards power,

i know guys are saying its a big change, but its not really,

in snowmobiling world, most carbed sleds perform Equal to a injected sled, but as technology advances and motors change they increase the power they put out so it is hard to actually compare....

theres is an injected trials bike made by ossa:thumbsup:

I think regular fuel injection will come before DI

DI has so many problems with fuel pumps in cars, I dont know how it could work well on small bikes

Beat me to it, I was going to say the technology has been around for awhile. By the way you are not old, you are wise! :confused:

DI on 2Ts is alive and well in the outboard motor world where it offers economy and power delivery similar to a 4T.

:thumbsup: At all these people that think two-strokes will still be cheap when they go DI. Have any of you guys ever priced out an injector for a DI two-stroke? You're looking at $300 Minimum for just the injector, never mind all the support hardware to make it work.

TM announced in the last dirt rider that they hope to have a fuel injected 2t on the line by next year

i doubt it. i don't see what the gain would be, if husky can get a 125 to pass euro3 standards with a carb what would the benefit be?

it would still be cheaper than an injected 4 stroke. and how often to injectors go bad, every 20 or 30 years?

come to think of it, i have never had an injector go bad on any of my cars, trucks or bikes.

oil injection into carburetor is not the same as DI into combustion chamber. :thumbsup:

someone asked if there were any two stokes that didn't require mixing the oil into the fuel tank, i doubt anyone was confusing auto-lube for di. :confused:

also you have the yamaha music divisions logo in your av, the motorsport division logo is different.

Direct injection is a lot more fragile, and a lot more complicated than port or throttle body injection.

Mine as well sell all ya 4-strokes cause two strokes are coming back and with a vengeance. I be glad to see these thumpers gone and 2 strokes back.
