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 The previous version was outdated and no longer supported.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

I got a new 2015 501s a few months back and thought all the smog stuff was off. They gave me a box with a few hoses and a canister in it. After looking at my friends husaberg 501 i noticed a part that i think is part of the smog stuff in the pic below. Where it mounts to on mine his just has a bolt which i belive is in the bag of goodies they gave me with the bike. My question is is it worth the time to take off and will it make any difference at all with the bike in any way?image.jpg image.jpg image.jpg

SAS/SLS secondary air system. On the EFI bikes, the SAS is only used for a brief period on startup, to bring the O2 sensors up to temperature. After that, the EFI switches to closed-loop control to ensure the CAT's have the required O2 to work properly. If you disconnect the harness you will not be able to start the bike unless you fit an electronic plug to fool the ecu that the sas is still there.

You will not get any gain from the SAS kit, but it may help the dyno boys as they need to block it off to map the bike (if you have a power commander). It sometimes can stop popping on overrun, some people have posted that they noticed an improvement but I can't quite see how, maybe with the stock ecu the lamda sensors may get a better reading with no fresh air in the system but with narrow band sensors I doubt it.

Vendors want you to take it off because they want to sell desmog kits. I'd leave it on there until you are prepared to dyno tune.
 
Just to make sure we are talking about the samething here. It is the silver piece with just a hose coming out and no wire coming out of it.
 
Remove your coolant thermostat and add XF2 coolant. We have the hoses which remove it without adding anything.
