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 The previous version was outdated and no longer supported.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

Baffle or Catalytic converter

Hi husky boys!
I've just bought a husky, and in box of spares found a cylinder shaped item which has metal "woven" filling, hard to explain, but my assumption is that it is either the baffle or catalytic converter, I'm 99.999% confident its a piece of the exhuast system.

My question is, with this removed, (what is it also, if anyone knows) will the tuning of the bike be out, or because it is EFI (te450 2009) does the efi automatically allow for this change in the exhaust system?

Thanks to anyone who can help
 
That is the cat. Is the O2 sensor still in? Thats the big question, if its in "power up" mode or not.
 
I agree, sounds like the catalytic converter. The exhaust will run a lot cooler without it. Leave it out and like sharpie 1 said power it up and then let it rip.
 
The O2 sensor is in the top of the pipe before the muffler, you either have a plug in that hole or the O2 sensor with wires sticking out of it. All the "power up" really is is a resistor plug that takes the place of the O2 sensor, not totally sure what it does other than tell the ECU to run in "power up" mode????? If you don't have the O2 sensor in than I would bet it's in "power up" mode. If you want more power out of it you would need something like the JD tuner or Power Commander, I've tried both and like the simplicity of the JD tuner.
 
I can't speak for the Power Commander, but I do have the JD Tuner on my 2010 TE 250. It's not exactly a power creator, mostly just an easy way to lean or richen up the fuel mixture at various stages through the RPMS.

Keeps the power output more or less smooth and predictable. Once you take out the Catylyic Converter, opening up the airbox/lid with an air filter, and plugging in where that O2 sensor - alters the air flow / fuel balance - so it'd be a good idea to have it 're-tuned' one way or another.
 
I see you are on a 09 TE 450, I am not sure how different it is from the 2011. On the 11 my jumper is under the seat right next to the ECU. The Jumper plugs in to the harness and bypasses the signal from the Exhaust air sensor, #4 below.
