Anyone else heard this one ?
Just got my latest edition of Aussie dirt bike mag, with an article of 2010 new release Huskies stating a European version of 125 fuel injected 2 stoke super moto Husky. No pics.

This is news to me!! If anyone hears of or knows anything about this project, please post or PM.
Very exciting to hear someone is working on releasing a two-stroke with FI... it almost makes sense that it is Husqvarna, when you look at that chain saw video in another thread...

Big drama talking about it over thumpertalk lol http://www.thumpertalk.com/forum/showthread.php?t=851531 (http://www.thumpertalk.com/forum/showthread.php?t=851531)

Just checked the Husky web site, they call it "Electric Carburation System" that controls both air/fuel and oil /fuel mixture, doesn't sound like full fuel injection too me

it says it meets the Ero 3 emissions test :)

The SM 125 features integrated ECS (Electronic Carburetion System) that administers exactly the right amount of fuel (both the air/petrol and oil mix) and that was developed in collaboration with Dellâ??Orto. The control unit also governs the ignition system. While keeping costs under control and sales prices competitive, this brings the two-stroke 125 engine to Euro 3 standards yet keeps all the advantages that two-stroke engines offer: lightness, performance and low running costs.

Here is something that you guys are leaving out. Many many many 2 strokes have gotten a bad rep over the years for 2 reasons. Smoking, so that would definitely help. Secondly, jetting. I have heard so many stories how their 2 stroke blew up in days, even minutes. It was because they didn't know what they were doing on the jetting. On a 4 stroke, it basically doesn't run if it is way too lean. On a 2 stroke, it runs great for about a minute. LOL Thus, EFI will help elimate the rumors about the EPA and will also help further our cause saying 2 strokes last longer. They do last longer with proper jetting and maint.

Hey Miedo...spread the good news on Vital please! :D

You can only do a 2 stroke post every couple of weeks. LOL. Patience.

Common! don't be a chicken!!!hahaha I liked the last thread with like 27+ pages!

I tried...... really, really tried, but could not continue reading that Thumper Talk thread on the EFI....
I kept on reading in the hopes that I would learn something and no one added to or explained what the system on the Husky actually did, only argued about whether or not it should be added to a dirt bike.. jeeeezzzz
Well I went to the Husky site and viewed the other side of the bike and zoomed in, then I took a "picture" of the screen so you guys could take a look.... to me it looks like they use a modified carburetor with some kind of electrical connectors that do... who knows what. I give them credit for trying new ideas, but would love to know more.

Look the word Miedoso up on google. :-)
As far as the EFI, the one guy made a good post on the thumpertalk forum. he talked about the ability to run a 50mm throttle body instead of the standard 38ish on a 2 stroke. So that does make sense. I'm not sure if that will be the case??? Either way, everyone needs to accept the probability that EFI is coming soon. Learn it, live it, love it. ;-)

Hey, the engine in that Husky is backwards! The ignition isn't supposed to be on that side! That can't be a real Husky! Impostor!

DellOrto Electronic Carburetor
Abstract:
A smart way to control A/F mixture ratio in small utility engines is needed to meet future emission standards and to improve fuel economy. Dell'Orto proposes a novel carburation technology, that joins an effective way to vary A/F mixture with a closed-loop electronic control strategy. The electronic carburetor is able to control A/F mixture ratio in the lean combustion range, improving both emission and fuel economy.
The mixture formation control is achieved by meaning of a solenoid valve on a main air bleed circuit. An electronic controller is used to drive the solenoid valve, according to the engine operating conditions.
The test engine used is a four-stroke, air-cooled, single-cylinder OHV engine with CDI ignition and mechanical speed governor. The control strategy is based on engine speed monitoring. The system normally forces the mixture on the lean side. An incipient lean misfire event is detected by cycle periods processing. When cycle-by-cycle deviation threshold is detected, then electronic controller forces the mixture to go back to the rich side, for the better combustion. Then, the system returns again to control the mixture in the lean range. By adjusting the control parameters, a lean and stable running is achieved. Results on SAE J1088 six mode test cycle shows a strong reduction in fuel consumption as well as in the HCs and CO emissions.
The system detects directly the lean boundary condition, and thus it's self adaptive to the various operating conditions such as altitude, wears, filter clogging, carbon deposits, tolerances, climatic conditions, fuels and so on. After start and transient behavior are also improved, since the system control A/F mixture according to the engine requirements.
This new development is designed to simply replace the standard carburetors. No additional sensors are required. Electric power requirements for control unit and solenoid valve supply are very low. Furthermore, the final product concept is shown, reducing the system to one component by integrating the electronic controller.

Some Cagiva motorcyles are using the same carb since 5-6 years already LOL Nothing new here!

MITO 125 - SP 525
GP fans all over the world recognise the race track pedigree and success this Italian motorcycle represents. The MITO 125 has 12 years of GP heritage and claims legendary status on which Valentino Rossi won his first National Sports Production Title.
Engineered for the race track the MITO continues to perform at the highest level whether youâ??re chasing the chequered flag or if you want to impress on the streets and is learner approved. Big bike GP looks and screaming 125cc 2-stroke performance arenâ??t the only draw cards on this impressive machine. Throw in quality 40mm â??Marzocchiâ? forks and spring pre-load adjustable â??Sachsâ? rear suspension and Brembo brakes all round complete the package to make you look and ride like a pro.
Cagiva are immensely proud to have been able to change what a being "two-stroke engine" means and to have been able to blend the new technology into the Mito 125. The research and investments made by the Company mean that gone are the days when the words "twostroke" implied only great performance. They now also mean caring for the environment. The integrated ECS (Electronic Carburetion System) administers exactly the right amount of fuel (both the air/petrol and oil mix) and was developed in collaboration with Dell'Orto. The control unit also governs the ignition system. While keeping costs under control and sales prices competitive, this brings the two-stroke 125 engine to Euro 3 standards yet maintains all the advantages that two-stroke engines can offer: lightness, performance and low running costs.

Where's the spec page Husky? I want to know what model Dell'Orto carb it is. I was looking through dell'orto.co.uk and their main page at dell'orto.it, and couldn't find a carb that looked like it. Maybe I'm blind today, I don't know. :-\
-
I wonder if we can fit that carb in a former Japanese 2 stroke bike? That would be cool! :P

So it is the VSHT, cool. I'm sure it would fit on any modern bike with some electronics. Hmm, maybe I should be called the mad mechanic or mad engineer. ;D >:D

I'm guessing thats a TPS haning off the side of there.
-
It is a TPS sensor on that carb. Go to http://www.dellorto.co.uk/merchandise/products.asp?CategoryID=2&PartsectionID=44 (http://www.dellorto.co.uk/merchandise/products.asp?CategoryID=2&PartsectionID=44) and they sell a TPS sensor for the VHST carb.

We remove the electronics from carbs on the 04 up CR Hondas, so not sure what all this does, but in the Honda case, it isn't better. Well maybe fuel economy and EPA requirements, but not performance.
