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 The previous version was outdated and no longer supported.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

2013 TE310 no power to injector

I purchased the bike used, young man that I purchased it off of said it ran but needed valves set. Needless to say I set valves no start. Tested fuel pump appears working and it’s getting power. Installed new injector and tested the plug going to injector no power. Tried turning it over still no power to plug. I’m going to check the wire to the ecu today. Any suggestions would be greatly appreciated. If I spray fuel in the carburetor it runs smooth until it runs out of fuel.

Let us know of your wiring investigation. My 2013 had a few broken wires due to the previous owner not having routed them properly under the tank.
By "carburetor" I think you meant "throttle body" :banana: but same results. Your most likely have a open circuit somewhere. Check the wiring diagram on the service manual for complete routing.
 
Also check to make sure the is properly grounded. One wire goes to the ECU, the other is a ground shared with the O2 sensor on the TE. If the previous owner did an O2 sensor delete, they may have disconnected the ground or it could have happened when you checked the valves. A broken wire/pin is possible as well. I think ECU failures are non existent on these bikes. The white/black (power to the injector) should trace back to pin 14 on the ECU.
 
I’m leaning towards weak fuel pump. I used my multi meter and checked all wires and found one problem the fuse p goes directly to the injector and it required a good cleaning then I pulled the control box cleaned with electrical cleaner tested port 16 which powers the injector and no breaks found so reconnected everything and pushed starter lightly to prime the fuel line and then cranked it over with the choke out after several cranks it started. Let it warm up a min and pushed in choke stalled instantly.
 
Looking at the electrical diagram it appears to be port 16 not 14? Also white and blue?

Clockwise till closed then back 2 turns was the start in my 2012…but I had 2012 Mikuni, you have Keihin
 
From the Manual...

"ADJUSTING THE IDLE Adjust the carburetor with warm engine and with the throttle control in closed position. Proceed as follows: - turn the knob (1) on the left side of the throttle body of about 34 clicks from the fully closed position, checking with the suitable device that revs are of about 1,950 RPM (turn clockwise to increase the speed and counter clockwise to reduce it."

I live in Colorado and use this knob to adjust the idle by ear. Altitude and temperature affects how my bike idles. I tend to open it up until it stops hunting at idle, if that makes sense. My recollection is that it's nearly all the way open above 9000 feet, but I started running a Rekluse this year, so I have to be more consistent with it or my bike will start walking :).
