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 The previous version was outdated and no longer supported.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

Throttle Position Sensor moving?

has anyone with a 2008 te250/450/510 out there had a problem with the throttle position sensor moving out of place? my 2008 te450 ran perfectly up until about 2 months ago and now its having intermittent problems with it coughing and farting down low and backfiring when I'm at constant throttle and low revs.
 
I've had my TPS apart, just to look at it, and mine really can't move out of place, I buttoned it back up and it's run the same for 2 1/2 years and it's never been reset. Yours might be different.
 
Think I'll move this over to 4st, Common Topics is for things that attach to Husqvarna bikes that share things in common with most if not all Husqvarna bikes - tires, tubes, grips, etc.

yer im not sure because I had my TPS and fuel injection set up by Paul Fini in mid 2008 and it has been absolutely perfect up until about mid March this year
and I took it down to my local Husqvarna dealer mechanic and the head mechanic said that my TPS had moved out of place when he hooked it up to ibeat 2 so im just asking around to see if anyone else has had the same problem...

TPS adjustment/Calibration is generally pretty stable once set up. Yours was good for 5 years until you noticed anything. So its not a problem, I wouldn't expect much different. It doesn't take much for them to be considered "OFF" it is very precise, anything but dead on is "off" based on the software but you won't normally notice an issue if slight.
Something to check once in a while- maybe when you have valves checked...

its issues now could be: coil ground, fuel pump/filter, temp sensor, loose battery cable, tps off, etc,.. they should be able to figure it out taking it in again: some instantly by hooking it up to the computer.

thanks for the advise, ill keep those things in mind when the next service comes up in a few months
 
I had that same issue after I had purchased my 08' TE510. Bike ran perfect, changed the oil, held the decompression lever with the key off and cycled the engine with the kick starter a few times. Turned the key on and tried to start the bike and would not start without any throttle and wouldn't stay running without any throttle. Almost killed my battery. Took it to Dan at Motoxotica and could barely get it running up to temp so Ibeat could read it. TPS was way off somehow. Dan couldn't figure out why or how that would happen. Hasn't happened since and it's been a few years.
