EVening, Gents!

 

Lou, the lady in the 2nd pic looks pretty good from here.

 

Jax? I thought it was Chip? Have I been confused all this time?

 

Someone in here started calling him Chip cuz he looks like a miniature Lou.

Thanks, Greg. That makes sense but guess I missed it somewhere

 

A long time ago.
Diamonds are Forever is on. One my favorites.

 

Well, life gets even better.

Got this from the JP cycle chat line who sells Rineheart exhaust..

Thank you for taking the time to chat with our customer care team, a copy of your transcript is listed below

Aaron: Thank you for using J&P Cycles Tech Chat. One moment while I review your request.

Aaron: Most likely who ever installed it cross threaded the sensor. the threads on the sensor are much softer than the ones on the bung so those will go out first

Allen: Ok, I'm wonder if they installed the wrong sensor or the one that's here broke, as it does not bottom out and stop?

Allen: Threads look good.

Aaron: the wrong sensor really could not be installed as Harley only has two different ones and the hook ups are completely different including what the sensor does

Allen: Ok, but what keeps the sensor from threading in to far?

Aaron: it would stop at the base of the threads. If the threads on the sensor look fine take a look in the o2 bungs on the exhaust and look for obstruction

Allen: The base of the sensor where the wrench would go to tighten is smaller than the threads, like having a 1/2" bolt with an 7/16ths nut for tightening

Aaron: does it have a lip where it looks like it has a reducer attached to it

Allen: No sensor has the treads which are about 3/4" in diameter and goes directly to the nut which is a little over half inch, 14 mm I believe

Aaron: you may want to unhook the sensor from the bike and take it into a dealer to see if they can match it up for you

Allen: Ok, but is it the senor or bung that stops it from threading to far into bung?

Aaron: it is the bottom of the "nut" that seats on the bung and there is a copper crush washer that stops it

Allen: Ok, then I will remove the front bung and look at it, was hoping for an easier way out, but thanks a ton for your help, at least I know how it should work now.

Aaron: You're welcome. Is there anything else we can assist you with?

Allen: Nope, thanks much


From what pictures I can kind of make out, it looks like the stock HD sensor has the nut you tighten it with that's larger than the sensors treads.

Mine the nut is smaller so you can thread it all the way through the bung.

So...removed the front sensor, damn if it isn't in hand tight and looks just like the back one.
Fairbault HD installed these.

Not to happy right now.

I'm wondering if they used wide band sensors and they don't fit correctly?
Not sure how to determine but it does say wos on the sensor, maybe wide oxygen sensor??

Which brings up the question, if I run the stock O2 sensors with the wider nut and it will tighten up, will the ecm function with the narrow band or do I need more dyno time?

That ain't gonna make me happy either.

Sure sounds frustrating Al. Best of luck on that......

Sux Al. I guess someone thought a cross thread was the best thread.
