• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     TE = 4st Enduro & TC = 4st 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 The previous version was outdated and no longer supported.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!

Great info guys thanks.

I would love to try a TC449 in fact i would love to own one to use as my off road only 4 stroke. Right now i have a TR650, TE511 and WB165 so i feel very well outfitted for anything BUT every time I ride my 511 on hard core off road stuff I wonder how awesome a stripped down TC would be (my TE is loaded with tons of DS gear). I think i would personally rather have a TC449 than a TE310 for off road but i have not ridden the new 310R, that might change my thinking.
 
Whatever the outcome, Confucius say more oil is better. I'm betting the Husky engineers are going....awww why didn't we think of that?

There is a good reason why older Porsche flat sixes had an 11 quart oil tank, just sayin'

Actually, a lot of Huskys have an oil breather built into the frame, which would of been perfect for this. This one is on BMW, and sending hot blow-by gas by the torque limiter no less. And then, to make matters worse, the oil quantities are lowered, dropping the levels in the case to where oil isn't there to cool the torque limiter. *palm to forehead*
So... Confucius say more oil is better.
 
That's a good question and I don't have an exact answer to that because manufactures rarely advertise known flaws. I can tell you that Malcolm Smith's torque limiter exploded 200 miles into the NORRA mexican 1000 this year and that Zip-ty racing had constant slipping annealing failures. Other pro racers I have asked acknowledge the issue and replace the torque limiter before major events. Most riders will probably not see slippage til late in the engine life, so far I am told the failures are when the engine is held wide open for extended periods of time during desert races.
 
So if you don't trash/race your bike it will not be an issue before late in the engines life? I believe that's why Husky has done nothing to compensate for it!
I'm still interested in a solution as I do race mine and on up to 35 or more degrees!
 
It's like a limited slip differential that is designed to give when you unload the engine and then reengage. I too am interested in a permanent solution. Keeping the oil @ 1150cc is a good idea. Other than that, the 449 platform is rock solid and has a massive 196 watt stator for light goodies.
 
Where do I find a filter like this? I want to try to do this in the simplest way possible but I don't want to run any lines into the airbox anymore. I'm done with that crap.

I didn't see an oil cooler on the Simonpavey bike, but I love their rear gas tank.
The team are working closely with Safari Tanks of Australia and Bianchi Prata Racing from Portugal to developing unique tanks that remove the sub-frame, Fuel Capacity:26 Litres (6.9 Gallons).

There's three ways to put an oil cooler on. You can use an oil filter cover adapter, weld and tap the case directly behind the oil filter or a combination of the two.

Edit: Simon doesn't use an oil cooler, he uses dual fans. He wishes to test Ty Davis's oil cooler setup in the future.
 
Oh yea, it's way extreme and even I wouldn't do it til I had to take my motor apart (which is hopefully never). Most riders do not have to have an oil cooler. If you are racing or running wide open for extended periods of time, then you should invest into an oil cooler.

On the 449 platform, you have to keep the torque limiter cool or it will fail. Another way to keep it cool is to submerge it in oil, which is what I have done with the oil breather mod. I run 0w-40 synthetic at slightly above the original BMW oil level (1150cc). My flow (which is very low on these engines) is greatly increased, this not only keeps my torque limiter cool, but also quiets my engine. It's hard for me to describe it, but if you own a 449/511 you know about that funky klunking, clicking, vibration noise the engine makes and is greatly reduced with my method.
 
I've been pretty busy this fall, but I will have time to put together a few projects next month. Also, after exhaustively searching for oil coolers, I decided to design my own. It is smaller than your fist and has a higher heat transfer than a twelve by twelve cross flow.
