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 The previous version was outdated and no longer supported.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

'12 TE310 will not start

Problem- My 2012 TE310 will turn over but will not start. This is what I know so far.
  • During last ride it was running fine although speedo unit stopped working and seems dead when ignition is turned on. It started up fine after a wash down.
  • It started to run rough during its weekly start up between rides, would not idle and eventually let out a couple of pops and stopped. It will turn over consistently but won't fire up. not even a slight crack.
  • It has a spark. I removed the spark plug and earthed it, turned the motor over and it has a regular spark visible. ( Tip- to get the socket into spark plug well easier, loosen off tappet cover bolts to take the compression off the Tappet cover rubber seal. It makes the hole bigger for fitting in the 5/8 socket.)
  • It has fuel flowing. Turn the key and the fuel pump makes all the usual noises. Disconnect the fuel line from the throttle body, turn key, pump starts and fuel shoots out......the throttle body is being armed with fuel when key is turned on.
  • Engine relay is making a clicking noise either side of hitting the start button during the starting process. Not sure if this is good or bad?
  • I have attempted to check for potential blockages in the injector but how do you know if its blocked? What is the best way to check if the injector is working correctly? Visual inspection looks fine.
  • Checked all wiring looms everything looks ok.
  • I am frustrated its been a while since last ride out and feel a need to cover myself and bike in dirt at high speed!:banghead:
Conclusion-Either the injector is blocked or its not receiving fuel into the combustion chamber due to the ECU having trouble sending a message to the injector to squirt. Could this be why it started to run roughly then backfired a couple of times before it stopped.....the ECU has packed it in.
I am close to taking it down the shop, but I like to try and fix issues myself to gain knowledge in case I am miles from help and need to get a stopped bike started.
 
To remove a dirty injector from the list of possibilities, remove it, and spray carb cleaner into the supply side. There's a little screen on mine that got clogged up and was producing similar symptoms to yours.

Also, check your intake boot for looseness and cracks. Mine bike also had similar symptoms with a cracked intake boot.
 
Sounds like my 12 TE250. I found that the Fuel pressure regulator bad after replacing pump, filter, etc. I've been through these issues on Husabergs. If the pump spins up you've most likely have a good battery and pump, you can see fluid being pushed up into the filter sitting on the tank bridge. Pull the air filter and spray a shot of starter fluid to see if it starts.

Still waiting for a moderator to approve my thread on sourcing a regulator from yesterday.

Good luck!

Thanks for all of the feedback guys and after all of that it turned out to be the spark plug. I tested it and it showed a spark however under compression ( according to the mechanic) it was a dud!!! Lesson learned- At the first, for a part that is so cheap I should have just replaced it to eliminate the possibility of it being an issue.
