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 The previous version was outdated and no longer supported.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

Help: 2011 TE 250 won't start

Hey Guys,

I searched this forum and web extensively trying to find some ideas. Hoping to post the specifics and maybe get some help from you guys.

Bike has 70hrs on it. Situation is; was out for a ride on Sunday, bike started and ran fine the entire day, loaded the bike and took it home, I didn't wash it because it wasnt that dirty. Tuesday night went to go for a ride and bike wouldn't start. It rolls over fine but won't fire up. Here are a few things I have checked and done:

- Bike is full of gas and both fuel stops are turned on
- Fuel pump primes normally
- Dash and lights all light up
- I can smell unburnt fuel collecting in exhaust so I feel confident it is getting fuel
- Pulled plug, checked for spark, both looked good but installed new plug (and set gap) anyways

If the bike sits for 20-30mins, and I try to start it again, it will stumble and almost fire up. Then it will fail to show any signs of life no matter how many times I try to start it.

My next steps/guesses would be valve check and maybe flywheel woodruff key is off? It seems like a timing issue because with fuel and spark it should fire but instead plug is wet and I can smell unburnt fuel in the exhaust. I would be surprised if it was valves because I had them checked at 35 hrs and they hadn't moved. It has never shown signs of difficult starts until now, it always fired right up.

Any other suggestions?

Could also be a failed engine temp sensor. If it fails it tells the FI to go full lean and the bike won't start cold but will occasionally cough. Its an easy fix just screws in to the back of the head by the cam chain tensioner. They are less than $15. and a common fail on these bikes.

I didn't think of that. Great idea. Is there a way to test the one that is currently in there? Sometimes it's a bit of a wait for parts for me as my dealer frequently has to order the parts.

Hey Bruce, I just saw this on another forum in regards to a TE630 starting problem like mine:
"Temp sensor most likely failed.. a known problem. New revised one from Halls is about $20.
One sign is that the fan runs non-stop even at cold start up"

I noticed mine was doing that too, but didn't remember if it had always done that, haha. I feel confident that is the problem now. Fingers crossed.
 
If your fan is running then I would order the temp sensor. Not sure how to test it but had the same issue.
 
I had a similar problem on my 2011 TE250, wouldn't start when cold, it was a faulty temp sensor fixed under warranty.
 
Just ordered ours for our 11 TXC...same problem, easy fix. Just a bummer that this thing can wreck your weekend.

Hey Bruce, Just wanted to say you were right. New temp sensor and it fired right up!
In other news I went in to the dealer to buy a temp sensor, got talking to the owner of the shop, and left with a new TXC310R. I traded in the TE towards it. Will be out for first ride in about an hour. Very excited :-)
 
I have also swapped out my 2011 TE310 temp sensor, suspecting it was faulty (but it was not the cause of the problem, as it happens). Both sensors had 1200-1500ohms when cold (room temp) and dropped to nearly zero ohms as the temp got up to 100 deg C. I tested it with an ordinary multi-meter and heating the sensor in a pan of water on the stove.
