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 The previous version was outdated and no longer supported.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

2012 TE250 Imploded

Are you sure about that redline figure.

My '12 TE310 had the 40 which I changed to a 45. 50 mph was 5-6000 range.

I did not do any calculations, merely a seat of the pants opinion when I took my older TC250 on a gravel road and topped it out in 5th. It did not feel like 80kph/ 50mph, yet it was nearly revved out. (No tach to confirm).
My SM 450R engine revs to 10500, and geared very tall, revved out 150kph/ 93mph (TC based engine, 5spd, 16/38 gearing)
 
It happened to me as well, I think they went cheap on the bearing. And it goes really fast, I stopped riding as soon as I heard the specific rumbling noise that a bad bearing makes, and i think if I I have ridden the bike one more time the bearing would have exploded. I ended up with just changing the camshaft, but be really careful about this, the damage can be extensive.

Yours is not an xlite, how many miles when you heard the rumbling? Which cam? Did you ever check the bearings when they were good, like pulling the cams and rolling the bearings, checking for play?
 
It's an '09 310. Bike had about 200 hrs when I bought it and I put another 10 on it before this happened. it's the intake cam, it never crossed my mind to check the bearing, I was more concerned about other things which I considered important: piston, compression, valve adjustment, suspension. They all checked so I assumed I bought a bike in perfect condition.. People I've talked to said this should never have happened unless the bearing was faulty to begin with. Of course japanese bike owners said they've never heard of such things
 
So I have been giving the bike a bit of TLC, 2010 TE450, really happy installing new bearings and grease nipples on the linkage (posted on another thread). Cleaned and put diletric grease on every connection. Check valve clearances and disappointed with what I find but happy I caught it before disaster struck. If you look closely you will see one of the bearing cage rivets wedged between the head bolt and hole. Another was in the allen head hole of the screw and the third I could not find, hopefully it was flushed out during the last oil change. As per some other threads these bearings were obviously cheaply sourced and are of inferior quality. Just got a bit more work to do now.camshaft.JPG

Wow, congrats on finding this as you did, are you pressing new bearings onto the OEM camshafts?

Yes that's the plan, just a bit concerned how the gear is mounted on the shaft. Does anyone know if the gear is keyed? The drawing I have doesn't show a key.

There really is no excuse for putting this kind of junk in a high-performance engine.
