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 The previous version was outdated and no longer supported.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

All 2st Will Ossa be first to the EFI 2 stroke off road bike race?

Dead serious. Do your homework. DI is not the hot ticket for a 2 stroke engine.
"Direct injection is designed for ultra low emissions and moderate power, not for the performance industry. They are very finicky and costly to service."

Just had to confirm, it's always hard to confirm when someone is joking on the internet. My BS meter went off though when you said experts say it sucks, as I was thinking experts in Direct Injection would be guys actually producing those systems, and people actually experienced in designing direct injection and shipping it to customers in mass volume say the exact opposite. Ski-Doo and Evinrude can't say enough about how well suited Direct Injection is for high performance.

Just did a bit of homework as you suggested.

By reading one article.

With input from two guys who work at the same company.

A company that is selling their own fuel injection system.

That is not direct injection.

So yeah....that seems like unbiased expertise in Direct Injection.

"Experts say" means "Guys who sell Port Fuel Injection say the system they don't sell sucks". In other news today General Motors announced today that Ford's are fine, if you don't mind fixing or rebuilding them daily.

"DI will work for more industrial like engines but not for high performance" means you will be stuck with miserable real world performance, so far the Rotax E-Tec's are only making 155-160hp out of their 800cc twins. If you can live with a measly 75-80hp/400cc cylinder then maybe you can live with direct injection. For those of you who like a more high-performance/less industrial engine than what Ski-Doo is throwing in their MXZ800 I would recommend just ripping the E-Tec system out and throwing carbs on it. Please report back to us the performance gains you get through this.

I didn't bother reading the article but just from the headline I can tell snowtraxtv has similar feelings about Direct Injection, their first article on their 800cc twin after being upgraded to Direct Injection is titled "800 E-TEC: Ski-Doo Messed Up This Time!"

I love new tech. It flips my switch. I have high hopes for the future of the DI 2T. There are a bunch of companies working on the DI 2T for enduro use and I have to believe that they will be successful. I am just going to wait to see the results confirmed before I plunk my cash down. Here is hoping they get it done sooner than later.

As I've mentioned before, a simple batteryless EFI system would be a great step forward for 2t dirtbikes. It will clean them up substantially & make them more efficient. The technology has been around for at least 17 years, so it's not like it needs to be complicated, expensive groundbreaking technology. It shouldn't add more than $100 to the cost of a production dirtbike.
The OSSA looks like they're headed in the right direction on paper. Let's see how it actually works long term in the real world with the typical hack rider.

I think above is quite correct as some young talented riders just rave about the modern (ie real new) fuel injected four stroke 250cc offerings. If the same enthusiasm could be generated in the two stroke models that would be great for the new bike owners. While the msrp might be within $100 as proposed above I am just guessing the sum of the cost of replacement parts not used on a carb model is probably more like $2000.
