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 The previous version was outdated and no longer supported.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

310 idle fail

Since about mile 50 on my TE-310 I keep getting a fail message on my display. The dealer scanned it but had no stored faults. I was told once I put the O2 sensor plug in that I would not get that fail message but whenever my bike idles, somewhere between 20 and 40 seconds later the message still comes up. Once I start riding I never get it but whenever I come to a stop or at start up, if the bike idles I get it. Any suggestions?
 
Mine says fail on startup also but without any actual symptoms. I understand the "fail" in my situation to be the computers recognition of not receiving a signal from the Lambada/Oxygen exhaust sensor (it is unplugged and capped). Yours might be the same thing.
 
its something it doesn't like at idle, im guessing maybe too much exhaust restriction. I set the idle to 1950 and it stays pretty close to that. How many of you use the start lever on the right side mounted on the clutch?
 
I have a 2009 model and mine comes up with fail during start up then goes away, I have never used that small lever, or the kick starter lol I might try it one day. Mine has had the exhaust sensor removed and plugged, and it idles fine, 1850rpm i think.

The Mikuni FI system on my TE310 has a butterfly stop screw at the "closed" or "idle" end of the throttle range. From the dealer, the screw was set so that the valve was still open quite a bit at the idle end of the range. In other words, it still let quite bit of air in when it should have been closed. Maybe this is for EPA, maybe sloppy set-up, IDK. I adjusted my set-screw so the butterfly completely closed off the throttle body throat, then backed off a bit because it stuck a bit when adjusted "full-closed". Then I set the TPS with iBeat.

I use the cold start lever only when it's needed. Like when it's been sitting in my cold garage overnight and it won't maintain high enough revs to stay lit. It usually only needs a little bit of pull. I have to baby-sit the lever so as to not rev it too high at start-up. My 310 is really cold-blooded. It takes quite a while to get it to normal operating temp.

The manual tells us we should never use the lever when the bike is warm, and we shouldn't need to. Mine starts right up when warm.

The FAIL indication should have shown up on iBeat. I don't know what the deal is there. You have to go to the history section of the software to determine what tripped it.
 
I looked and couldnt see an idle screw, my bike also had no throttle stop. Once I do the txc ecu and injector I was going to have the tps reset, tried finding someone in town with Ibeat but no luck so I will have to take it elsewhere
 
The idle adjust screw is on the right hand side just in front of the rear shock and before the kick starter.
 
the video was helpful and this could be part of my problem but I dont know if I should mess with it without ibeat.
 
If you see fail on start up and it disappears its nothing to worry about. If fail stays on the dash when the bike is running then you have a problem. It's fairly common to see fail as the bike first starts, I think it may be battery voltage related but as long as it disappears there is nothing wrong with the bike.

In your situation if the dash is showing fail when idling then it should show a stored fault in the ECU. If there are no stored faults then it could be the dash itself at fault or again a voltage issue. Might be worth seeing what battery voltage you have when idling?

How long till it goes away? I've been letting it idle for a few minutes and then I cycle the key and take off before the fail has time to come on. Everytime fail comes up it doesnt seem to go away without a key cycle.

I wonder if you Lambda plug is unpluged or not connected properly. Mine would do that when I unplugged the Lambda sensor, but didn't plug the O2 sensor in.
