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 The previous version was outdated and no longer supported.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

Question/idea regarding 02 sensor...

I managed to do about 120 miles so far and the bike is running well. I'm trying to get it to stumble and I can't get it to do anything strange. Previously if I was in say 3rd gear and would lug it way down slow then try to gas it I would typically get the terrible banging/knocking sometimes accompanied by a stall and I can't seem to make this sucker do it any more. If that "feature" isn't gone it sure is improved- to the point that I can't make it happen. I'm in a parking lot trying my best to reproduce any of the nagging issues but it refuses to do so. On the other end of the spectrum, I ran it up to 85, chopped throttle- back on the gas hard- I just can't get it to buck/hiccup/cough/sneeze etc.

If another brave soul would give this a shot to validate my findings that would be great, as this bike has "good days" and this may be one of them...

What was the temp today. mine always seems to like cool days more that hot. (well, I do too)
 
If you are interested, I've just put the LC2 on my bike and have a thread going here about it. This morning I flashed the AFR to 13.2 (10% richer). The bike is a freaking animal now. My thread has links back to ADV and the testing I've done.

Been following there too. You have gone much farther in to the problem than I am willing to. Mine runs fairly well with the"Eruption" mod and the single GPR exhaust but I'm no less interested in the outcome. Keep the reports coming. Thanks!!
 
I've followed DRZcharlie too- and yeah, I'm not digging in that far! I'm not spending any money to make this thing run right. I've done the eruption and canisterectomy, removed my baffles and had the moss update. Still runs "not right". I'm happy to say that with the 02 spacer it's "fixed". Or at least it is for now. It's running great, it's never run like this. I wish I had more ambition- I'd check the AFR's, etc. If it still won't run right after this I'll probably replace it with a DR650

I would be happy to throw this on my Strada! If you are still up for making another, I will PM you my address.

I was curios to to others who have used a spacer so I did a search. Most sellers of the extension say it will lean out the mix. Now I am intrigued

I wonder who could convince DR Z to run one and log it with his new toy. (hint hint charlie)
 
In a 2 sensor system it is used to trick the ecu into reading an artificially "lean" condition on the downstream sensor (post cat) to ensure the catalyst has done it's job. There's more to it than that, but in a nutshell- that's what the second sensor is doing on a car.

Now a bike (or early fuel injected car) different story. One 02 sensor that is monitoring and adjusting the mixture. Pull the sensor out of the direct exhaust stream so that it's sniffing less exhaust and I'm guessing it's gonna tell the ecu that the mixture is weak. Just a theory. If it's doing the opposite of what I want it to do then I'm at a loss because it's running fantastic.

If you want to try it on the cheap go to your favorite auto parts retailer and go the the "HELP" section. Get a set of 18mm spark plug anti-foulers. Run a 1/2" drill bit through them and paint it black (not required)

Install and behold the wonders!
 
Just noticed something- it's a cool night here in the low 60's... And the flashing snowflake I've grown so used to since installing the eruption is not there...

That's weird, no?

You buy it, send to me. I run it, log the data and forward it to you. Will that work?
 
I can whip up another one and get it to you. I'm not sure the 90* ones are gonna fit. Once DRZ establishes what effect it's having (if any) I can go about whipping some up for people to try.
 
This will work. Kyle I sent you a pm with my address information. I will run my bike a couple of hundred miles this week to establish a stable baseline running my current AFR of 13.2. Once that is done I will post the log. Next I will put the extension on, run it for a couple of hundred miles, post the log and we can discuss it and go from there.

Theoretically 02 sensor position on the edge of the ID of the pip or directly in the stream of the exhaust header shouldn't really make a difference. If the 02 probe is within the inside diameter of the pipe it does become more susceptible to condensation while the pipe is hot or when it's cooling down which could cause premature degradation of the sensor. What is more of a worry is whether there are leaks in the header or the connection to the muffler or perhaps leaks in the intake somewhere. I think there was discussion somehwhere here about possible intake leaks? However, this is the least of our worries.

The snowflake is directly related to the air temperature. The air temp shows on the dash. What temp was it showing ?
I have the temp probe from my wuka plug strapped to the frame steering head tube, so when the bike is stationary it will very quickly show the temperature rising on the dash just from the heat the engine and radiator are radiating onto the probe.

More than happy to give this a go!! :-)
What length is your spacer?
Would this be similar/ same?
Is the ID the same as yours (just going by sight?)

What a bummer that this guy doesn't sell to OZ, I'd be happy to get a few to play with and/ or pass on to the locals.
18x1.5mm thread sounds right .
I also can't see any issues with condensation, as exhaust gases are hot enough to heat/ warm the extension piece and the sensor itself well beyond a point where any moisture will dry/ evaporate....

Spacing the sensor in a single sensor system, can logically ONLY fatten the mixture.
I CAN see a variable as to the length of the spacer, as the exhaust gas composition will change the further recessed the feeler probe is located.
 
I agree that the spacing should affect the mixture richer but how much space (length) creates the correct enrichening? I don't know but it sounds like Kyle is onto something much cheaper than I am using. I hope he is right. What an easy fix this would be. As for condensation, it does form inside the header when cooling from a superheated exhaust as I had he 02 sensor on my VStrom corrode badly. The tech consulted with Suzuki (warranty issue) and they told him the corrosion was a result of exhaust header condensation. That may not be the case in this bike though. Glitch I will concede that this may not be as much of problem (if at all) when heating the header to temperature becuase the condensation is being superheated and dissipated quickly.

Logically, this would offset the chance, at least to some degree, to which the ECU can adjust mixture while using IAT mods.
The length/ depth of the spacer would be trial and error and possibly slightly different for different bikes and different spoofer types.
It might actually work well enough on its own without the need of a spoofer.
So....a piece of "pipe" with a looong, external 18x1.5mm thread and an 18mm set-nut on one end...and a female 18x1.5 thread at the top would be ideal.
The whole thing possibly 2.5" long with a 1.75" thread on the bottom.
Just take the hacksaw to the thread to shorten...and if cut too short, start with a new one and/ or trade through the forum here.

Alternatively...get a few short and/ or angled ones from Ebay and use one or a stack of them.
 
glitch- that looks spot on. You'll just need to open it up (on the inside) I'm going to send one to Charlie today hopefully... i'm on day 2 and all i can say is that i love my husky again! it's noticeably happier... smoother running at 70-75. i filled up yesterday and at the one gallon used mark i was at 57.3 miles. Whatever effect it's having cant be much because the mileage isn't really off from what i usually see. strange. And i posted incorrectly about the snowflake... it's there. Must have been more ambient heat than i realized yesterday. I'll go measure my spacer right now, it's actually 2 screwed together (they come 2 in a pack) It's approx 1-7/8" long. I hope it keeps running along like it is... and i cant wait for someone to actually validate what i'm experiencing. I may be crazy but the exhaust note seems deeper at all rpm's. Winding out each gear, the engine really sounds and feels much more happy and lugging around in one gear too tall the bike is now happy to chug up to speed instead of coughing and banging. Again, apprehensive about saying it's some miracle, but it sure seems promising.
