Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!

other wise i just went to you tube and typed in direct injection and got it to pop up.

Thats what I don't understand, Athena makes it look like you can buy this off the shelf as a OEM. A version of it is being used by Ossa and outboard guys. Why cant Husky do this???

Direct injection has been available on two stroke outboard engines and snowmobiles for a few years now. I don't know why it is taking so long to get to motorcycles.

Frankly, DI e-tec skidoo's have a higher failure-rate than any other model they make. I know there is a fascination with it, and it opens doors to new markets, but I would really just prefer a conventional FI 2stroke 1st. They need to proceed through a natural progression of technology IMO and not put the horse before the cart.

The EPA's jackboot may not give us the luxury of waiting for natural progression.
A guy I know said he trades his ski doo in every year for a new one because the top ends go.

The APT Smartcarb might send the DI to the back of the pack for awhile. Been reading up on these APT Smart carbs now for a few weeks.
It's a long thread, but read up below. Good results by those popping for the billet version. The company is working with OEM's now like GasGas and others. This keeps the simplicity of a carb bike (no added electrical circuits, no fuel pumps, no injectors etc.) with the benefits of a EFI set up (better atomization, power and torque with less emission and fuel consumption). What I really like is altitude and temp variation is accounted for by this design, NO JETTING to ever have to do. They will have a cast version out in early spring. I have been emailing them about one for a new Husaberg I am buying. I know, blasphemy on the Husky board!

"Smartcarb" is such an oxymoron!!
It is the topends that blow on the E-tec's and often the big end also. I have no proof but IMO to get them clean, they don't run enough oil through them. They are absolutely miserly on oil consumption. So it isn't the DI componentry per-say causing the failure, but the goal of DI is clean-running and the failures are a bi-product of reaching that objective. DI doesn't produce more power than FI in fact ski-doo's SDI (semi-direct injection.... transfer-port style) made more power than their DI.

the athena system is nothing new. the inventor tried to market his innovation since 2005 or 2006, and athena jumped in. the screenshot you can see in the video at 0:23 is even taken from his old website.
ossa and other companies use other systems.
parts availability is still the limiting factor, limiting the engines to a maximum rpm of ~9000 for the moment. that's not much for a 250/300, and definitely not enough for a 125.
(for a 9000 rpm two-stroke engine, you'd need to use the parts from a 18000 rpm four-stroke engine. there's not many of them out there...)
then there is fuel atomization. in carburetted two-stroke engines, or with injection systems that inject into the throttle body or crankcase, there's plenty of time for the fuel to atomize. in direct-injected engines there isn't.

so far, the only visible result of the "dicc" system (or "lucan engine", as it was called before that) is an 8hp 50cc engine that revvs up to 10500 rpm, ... there's a reason why they don't show higher rpm.

because two-stroke direct injection still ain't that easy.
