• 2 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     WR = 2st Enduro & CR = 2st Cross

  • 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 The previous version was outdated and no longer supported.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!

Fuel Injection?

I wonder if SP was able to purchase any EFI/DFI development that had already been done on that rumored DFI smoker??

The technology Husky was using, is owned by an Austrian Company, not BMW. KTM had rejected it, to use the Orbital system. It's actually simpler than the Orbital DI. KTM may use it yet.

Forget EFI / DFI. Stick with something simple like a Lectron Carb. EFI produces no more power than a well tuned carb. So why have it ?
 
If you have DI and it cleans up the 2 stroke and makes it more fuel efficient, what is the negative here?
Riding to and from the trails as well as more fuel to go further. HMMMM, ya simplicity like in 1970s

Complexity. I worked at a dealership when DI two strokes first came to water craft. We had Kawasaki (FICHT), Bombardier (Orbital) and Yamaha, everyone thought it was going to be great, and they ARE great....as long as everything is working. Injectors (especially the very high pressure DI injectors) fail, fuel pumps fail, if it is going to be DOT legal it will have an O2 sensor...none of that stuff on a carb'd bike. I can tell you from years of first hand experience working with DI two strokes that when something does go wrong, its a nightmare. The idea of a DI two stroke sounds great until you start to feel the realities, then its not clear they are worth the trouble. Some people will think they are worth the extra complexity, but I do not.
 
I split the difference with a SmartCarb on my WB165.....no injectors, no fuel pump, no maping issues. but I do have better fuel economy, more power, smoother throttle response, no jetting to change once a simple knob is used to dial it in, runs cleaner, without the complicayions of FI or DI. Until the dirt bike word catches up the the car world I'll stick with simple all be it a modern carb.
 
Yes, its billet, some other details are different, but its still basically a copy of a Lectron and thats not a bad thing. I agree either is a big step up over a normal carb.

I can jet a carb in 20 minutes

I can adjust my tuning in 5 seconds on my JD Tuner. I've never needed to, though. :)

I've never had them fail on an EFI bike. And I've never had a jet clog, a tang need bending or a float bowl seal need replacing, either.

Running a carb means lighter weight, and it's easier to do a field repair on a carb when you experience a failure in the middle of nowhere. Those benefits are more important to some than others.

EFI is vastly superior for emissions control. And before long it won't be an option, it'll be required for that reason alone. Best get used to it. It's time motorcycles carried their share of the environmentally conscious load.
 
I to have been involved with DI marine world. As Kartwheel68 said they are great. Yea learning curve. Be careful what you wish for. New recent breakthrough in battery technology will results will be that the only wing a ding ding will be on the menu at Buffalo wild wings.
I noticed no one made reference to it helping the enviroment.

Because I'm hopelessly hopeful that we Kalifornians might get street legal 2 strokes again. Not because I'm expecting more power. And now I'd like to re-direct this thread back to what Husqvarna might become...

Exactly. The best thing about 2strokes are their light weight and simplicity. Lectrons require little to no fiddling once set up properly, DI or EFI is something I don't need or want unless proven that it performs leaps and bounds better than what we already have.

Exactly!! the carbs wont leave you stranded miles from the truck either
 
in the late 90s Honda ran Paris Dakar rallye with a DI technology. no breakdowns. efficient and clean. Then shelved the project because they wanted to start a 4 stroke revolution. 20 years later what do you have?

The EXP-2 was both carburated and FI, but it didnt have DI.

To be blunt, emissions from dirt bikes might be a visible political issue, but the contribution of pollution from them is completely and totally irrelevant. They are not even a drop in the bucket.

It's a bunch of BS. When I get my RED sticker (restricted to certain seasons and riding areas) for my trail bikes that don't conform to emission standards for a green sticker (all year round, all public riding land), there is always a little pamphlet that says something like "your trailbike puts out more exhaust emissions than 100 new vehicles per mile" and blah blah blah. Sounds pretty clean to me. I have been told that the public areas are closed to my WR and my other two stroke bikes from May till October because there is an inversion layer in the area where the OHV parks are. Really? An inversion layer? There are windmills out there, because it's the windiest area of our county. I hardly believe that there is stagnant air out there.
