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 The previous version was outdated and no longer supported.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

TE310 2012 Exhaust Catalytic converter?

H

A Class
I've just taken my header pipe off and the catalytic converter fell out, see the photo below.

The shop I bought the bike from told me it had been 'fully uncorked' whatever that means, I thought 'uncorking' meant removing the cat converter. They also installed the power up (12 point injector/ECU), I have the old injector which is 4 point here and ECU.

Can I leave this out? The washer/ring to hold against the larger outer pipe is stuffed anyways.

Does the bike need to be re-tuned?

"Powered up" means they should have removed it.

Should not have to retune it if COs are at 100 100 100 but if they tuned it for a plugged pipe you may have to.

Given they just left it in, I guess they also left the COs at 100 100 100.
 
OK, well I haven't been for a decent ride yet to test it out. It feels and sounds better in a quick run around the suburbs. A bit more free flowing and a bit quieter.
 
Well, that part in the picture looks like the spark arrestor to me. Totally different than the catalytic converter.
 
That's the cat. The SA is a screen.

Thanks Johnrg, I realized my mistake after I removed the muffler today and took it out. SA is still in the tail end of the muffler of course.....
 
When I removed the catalytic converter today, the already lean condition of this motorcycle seemed to worsen with the better flow out the exhaust system. Trying to improve the running or this engine, not worsen it.
 
Not surprising. Do a reflash and uncork at one time... A quick drive to Zip Ty and you're set. I ran the stock map but it must have the open filter cage and has no top end. It is simply tuned to roll downhill out of the dealer in that trim, popping all the way.
 
Man, nice dealer uncork on your bike... I wonder if they even reset your tps after replacing the ecu and injector let alone adjusting the co's.
You are blessed to have zipty nearby though. They know these bikes extremely well. Good luck.
