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 The previous version was outdated and no longer supported.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

2009 TE 510 Lambda O2 and tilt sensor resistance numbers

Hi.
Have an intermittent splutter, pop, stall issue on my 510.
Could anyone tell me the resistance values for the lambda and tilt sensor delete resistors please?
Would like to rule those out.
Thanks.
 
That would be wonderful, thank you.

Seems to be related to heat or moisture, but can't yet tell which.

What makes you say they are unlikely causes?
 
Old guy,

Found your thread re green/red wire. Had already checked that and found no worn sections though did note other wires leading to fuel pump were questionable. Re-insulated those.

Also noted that lambda delete shrink seal was cracked and the connection/resistor wet and dirty. Removed shrink seal and re-sealed with silicone. This part is on the green/red circuit so perhaps is a candidate.

Tilt sensor reasonably contaminant-free.

Resistance value for lambda measured 2180 ohms.

Tilt sensor resistance measured in ohms:
Orange to Black 1872
Orange to Grey/Black 1861
Black to Grey/Black 438

No riding until the weekend so will report results then.

Cheers,
ballbag.

I was the wrong guy to volunteer for this assignment, me and electricity DO NOT understand one another.

I only had 2 resistors, I measured them at the resistors which the 2 resistors are what is under the black cap, I never knew 2 bare resistors were in there. I just went out to re-do it because I only got 1 to measure and I forgot to see what wires it was on. The 2 resistors actually both connect 1 of their ends into the striped wire. Anyway, I previously got the Black to Striped resistor to measure 1.116 with the ohmmeter set at 2k, I could not get a reading at any other setting. The Striped to Orange resistor, the meter would only flash numbers and I never got any kind of reading. my tilt sensor was full of mud, water and oil. My bike runs fine, but after messing with the tilt sensor, my temp light, which is my fan power from the ECU, isn't working so good, so a bad day for me.
 
I thought only the SM's had a tilt sensor. I have a blocked off set of wires after the three fuses under my seat by the rear fender.

OHR, I figured your an expert electrician now!
:)

I've done alot of wiring work and I still have zero skills when it comes to electricity.

The TEs still have the tilt sensor wiring/plug. It is plugged off with 2 resistors as far as mine goes. These resistors (I think) tell the ECU that everything is OK with the bike, i.e., it's not tilted over.
 
Gotcha! I never have had mine shut off when I lay it down. My old Yamaha wr250r I had would shut off after 3 seconds. Very annoying!
 
FYI - Bike is now running well. I suspect water around the lambda-delete resistor was the culprit.

Adjusting the throttle to be completely shut at idle has healed the off-idle bog. Throttle response much more predictable now, though I suspect a re-mapping of the fuel would see further improvement as it's running a Barrett slip-on 'muffler' (doesn't muffle much!).


Anyway, the bike is an animal. Last dirt squirter I owned was the legendary YZ426F, and I reckon this one's even more of a thrill to ride. I feel sorry for that rear tyre.
 
Check your charging rate with the bike idling and revving, should be 13.5v-14.4v

I just had one of the 3 phase yellow wires from the stator get rubbed bare under the tank (no pic) resulted in flat battery and uneven running issues.
