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 The previous version was outdated and no longer supported.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

OSSA encounter

I got a chance to check out an OSSA tr280 trials bike yesterday. A good buddy of mine recently has gotten the trials bug and this is already his 4th trials bike in a little over a year I think. Super fun bikes to play around on and I have even borrowed one of his spare bikes and entered a competition with it. Don't ask about my results. haha. Anyway, he ordered this ossa a few months ago, and after the dealer doing quite a few upgrades it arrived a few days ago. I went over yesterday to check it out and all I can say is it is very cool. The rearward tilting engine is something else. It looks like a v twin with the front cylinder missing. Cool little tricks everywhere and just a neat bike in general. I didn't get the chance to ride it as I am kinda out of action right now after a knee surgery, but as soon as I get the chance to ride it I will give a report. It does sound nice though and appears to run nice and clean once warmed up. The starting procedure is a little odd. There are two kill buttons on the handlebars. One on the left to kill the engine, and another on the right that acts like an electronic choke. When cold you need to hold down the electronic choke button and don't dare touch the throttle. A couple of kicks and it fires up, give it 30 seconds to warm up and then release the electronic choke button. Once it's warm there is no procedure to start, just kick. The DI programming seems to behind where the FI programming is on modern mx type 4 strokes though. If you do accidentally touch the throttle while the bike is sitting or still cold it will flood the engine big time. Like the early 4 strokes did with the pumper carbs. If you do this you need to disconnect the wiring harness from the injector and kick it with the throttle wide open and she fires up 3rd or 4th kick. Then quickly reconnect the harness to the injector. It kinda seems like the engineers got a little ahead of themselves with the DI and its programming, but for a small company's first shot at it it's not too bad. Another year or so and It should be spot on. Once it's warmed up it sounds super crisp and very responsive. I can't wait to throw a leg over it. Here's some pics.

Very interesting. Seems like the flooding issue should be an easy fix. Maybe the enduro bike will actually appear some time soon.

Yep, much like the early FI mxers I bet it will only take a year or two and they'll have the programming much improved. From what I hear, it sounds like the enduro bike isn't going to happen. What a shame, as it would be a welcome addition at the races.

Ohh, I almost forgot.. the premix ratio is 120:1 ****************************************! :eek:
 
I keep seeing these referred to as direct injection, not sure where that came from. That might have been their original plan, but that is not what they ended up with.

Direct(ish) injection. direct that it is going into the engine, not into the external intake tract.
Just how I've seen quite a few manufacturers state that their engine has DI, but apparently it stands for direct ignition :confused:

everyone says it.. I'd like to see true direct injection on two smoke dirt bikes. like what envinrude have on their e-tec engines, or the ski doos.

Direct injected 4 stroke would be pretty cool too

Back to the Ossa, i want one of their explorer models, looks hawt
 
I also had an OSSA encounter at a local SoCal trials event at Lark canyon, it sure is and interesting machine with normal ergos wrapped around the out of box engineering. Very cool looking machine.
PS the event was alot of fun and I even participated as a tender/minder/catcher/observer (I dont know their lingo).
 
I am still waiting for the enduro to actually materialize... deposit has been on the books for 2 years(or so).

Looking at the bike in person I also thought "this isn't direct injection I can see the injector right there at the base of the cylinder, must be more like direct case injection?". I remember when it was first shown to the public and it was touted as direct injection. Anyway, I'm just a dipsh#* farmboy, so who am I to rename it. Can't wait to ride it though, DI, FI or whatever it's called it looks like fun.
 
I have a 2014 Explorer and I can tell you it is a blast!

They solved starting issues, push the kill button once and kick it when cold (no throttle)
Turning the throttle when not running doesn't seem to do anything, since the fuel pump is not running...

I understand they new map has a setup that I'd you somehow flood it, just hold the throttle open and kick. The ECU will turn off the injector until it starts (or so something like that).

I wanted it for mountain trails and it really works well for that. Super light
I did a quick (perhaps not very accurate ) weigh and it is about 75lbs less than My 2009 KTM 300 XCW!

I have loads of pics and some video if anyone is interested,

I saw one a few months ago. I was on my gas gas and I stopped and had a nice chat with the lady. Not sure what model ossa it was. I looked like a trials bike with a seat. Seemed pretty cool! It was FI also, sounded pretty crisp.
 
Let's see some vids
Ok...
