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 The previous version was outdated and no longer supported.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

Problems with my 07 te450

Hello all. This is my first post here as its also my first time owning a Husky. I bought it two weeks ago for what I thought was a decent deal, but am now plagued by a problem I can't seem to figure out. I have an 07 te450 with 1600 miles. The bike will start up just fine and idle seemingly perfect until the bike heats up. At this point the idle will cut out and the bike will die. I can restart it after but it won't right for more than a few seconds.If I'm riding the bike it won't cut out until I come to a stop.While its cold the throttle seems crisp, but as soon as it gets hot it will cut out with throttle. I've already replaced the battery, thoroughly cleaned the carb, changed the coolant, spark plugs, and cleaned the air filter. The only issue I saw in the carb was a corroded diaphragm in the accelerator pump. Can this be jetting? The bike did sit for a while, what issues come to mind? I'm at a loss and I'm fiending to go riding already :/
 
Probably a good idea to mention that I'm getting a fuel leak near the bottom of the carb even after cleaning but can't seem to pinpoint it. I believe its missing an o ring for the plug but it also looks to have gas above the plug on the bottom of the carb.
 
You'll need to keep trying to get the carb to working better, if there is a surplus of gas going into the combustion chamber, it will start OK when cold, because a cold engine needs a super rich mixture. As the bike warms up, it needs a leaner and leaner mixture, and if there is something allowing too much gas into the combustion chamber, that could cause your problems. This pic is a friend's Beta 450, where the emulsion tube with the main jet fell out inside the carb and the bike was sucking waaayyy too much gas thru the opening.

And since you mention heating up, I'll throw this in the mix:

When the bike is cold, there is no pressure on the coolant system, as it gets hot, the coolant system is pressurized and if you have a head gasket leak, the pressure from the coolant system can force coolant into the combustion chamber especially on the intake stroke.

Get the bike up to the temps when the malfunction happens and pull the plug, see if you can see or smell any coolant on the plug. The pic below was mine but my problems happened with trying to start the bike after a 5-10 minute stop, the coolant would get pushed into the combustion chamber and drown the spark plug.

Thanks huskyrider, ill be sure to check the plugs. I just ordered brand new jets, gaskets, needle, basically everything for the carb and I'm going to have a pro piece it together. I'm a few problems away from using my minute of riding time to jump into a river with concrete boots. I need to ride!
 
Well after all this time I've come to revive my old thread. My (somewhat) local shop ran some tests and found it was the stator going bad. This was over one month ago, and now I've had my bike stuck at the shop with continuous false promises of getting me a new stator. I've searched high and low, UK, AUS, and every US website I could find and I can not for the life of me find a stator for this bike. Do I have any other options? Possibly somewhere that will rebuild the stator or another stator that's compatible with my bike? It's been two months since I bought this bike and still have yet to even ride the damned thing, I'm losing faith fast now. The warm weathers already halfway gone and I have no end to this issue in sight. Thanks in advance for any help, I'd do just about anything at this point to just ride.
 
Yes, unfortunately they said 4-6 weeks because its on backorder. Makes me wonder where my dealers promise of getting one in a week came from.
 
Maybe the staor can be rewired/ reconditioned.
Hang in there I had an 06 450 and it was a real gem and loved it-also very reliable. get this fixed and Bobs your uncle for sure.
 
Maybe that will do the trick, I have yet to see the stator since the dealer is around 50 miles from where I live. I finally got an email back from Husky corporate and if they can't give me a timeframe I'll have to try this out.
 
Okay, so with Husqvarna HQ stumped and my dealer putting me off, I was thinking of doing this conversion. http://www.thumpertalk.com/topic/949122-trail-tech-stator-kit-install06-te450/ Has anyone seen or heard of any problems with this? 06-07 450s are pretty much identical from what I've heard. This seems like the most cost effective and quick option. As far as I've read, sometimes a stator rewind isn't enough for a dying stator. Any advice on proceeding?

The Trailtech stator will work great, the only problem is they are not plug and play, its set up for a KTM and Trailtech has no interest in helping Husky owners. I converted my '05 with Trailtech parts, not all that hard as long as you have a little electrical knowledge. That write up on TT is great info, plus you'll get more power out of the Trailtech.

Rewinding is an option, I would bet your ignition coil is the culprit, if you look at the pole at the bottom left on that picture on TT you'll see that one pole has smaller wire wrapped around it, that coil makes the power for spark, thats the one that needs fixing. When you pull the ignition cover off you'll see a part with 2 wires going to it (for ignition timing) bolted to the top above the stator, I've seen one of those go bad as well, that part can be picked up at a good KTM dealer.
 
Digging into the bike now, seems the oil was of the wrong weight, non synthetic and toasted. Ive underestimated the previous owners ability to cut corners. Next up, into the stator! Wish me luck guys, ive wired stuff in my house but never on a bike before, this may get interesting.
 
Wrong oil filter was used, allowed shavings a plenty into the flywheel thus destroying the stator. oh boy im in for a real treat for the futurr of this poor bike :/

I have the same bike, and have always used petroleum based oil in it. I have 9000 miles on mine with no problems. Lots of TE owners use petroleum based oil in their motors, either 15-40 or 20-50, so I can't imagine what weight oil the former owner used to cause a problem.:excuseme:

I can imagine a wrong oil filter not being good for an engine, but I am still wondering where the "shavings a plenty" originated from. Was this because the oil filter was too restrictive and internal engine parts weren't getting the proper lubrication, so something grenaded?:thinking:
 
Well, after taking a look at the stator I'm almost positive that It's the issue. After checking the contacts, the varnish has worn off of many of them. On some even the metal is worn down. I honestly have no clue what could cause so much damage, it makes me worry about the future of the bike :/ I'm considering selling and buying a newer model at this point because with that much damage to the stator within 1600 miles who knows what the hell else might go wrong.
 
Diagnosing these types of things can be problematic through the internet...

Personally I would find a decent shop/mechanic. At some point I am considering picking up another 2006 or 2007 TE, because I really like those. So you may find that bike fairly easy to sell.
 
Unfortunately, I've discovered today that my bike is an oddball. It's a 'Euro 3' version of the bike that somehow made it to the U.S. One of the few differences between the U.S. and euro model is the addition of a radiator fan and a different stator... Luckily halls cycles clarified that for me. I was wondering why the damn fenders kept coming in without room for the cdi which is mounted under the seat on this model.
