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 The previous version was outdated and no longer supported.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

JD Jetting vs PCV

Another vote for the PCV, though it seems you've went with the JD. I can't imagine my bike running much better than it does now. Just thinking about how it ran stock makes me sick, lol. It was such a mess. Low rpm stalls, gutless power, and a host of other problems. ZipTy has done a lot of work on my bike, and every single thing they've done has pushed the bike into a whole other level.

PCV, ECU flash and an FMF slip-on transformed the bike. I'm sure you won't be disappointed with the JD.
 
I am wondering if I have to weld on a new bung for the O2 sensor for the PCV.

Motomummy has it for $279 which is $20 cheaper than hardracing.com but motomummy doesn't have it in stock. I will go with hardracing too as they have a 3-4 day service.


Does anyone have a map they will be willing send my way to get me started with?
 
I believe you do need to have the correct bung for the O2 sensor. However I'm not sure of the sensor thread size. Tinken can probably tell you off the top of his head.
 
I bit the bullet and ordered the PCV and auto tune. I guess I'll sort something out with the JD.

It was mentioned earlier about flashing the ECU. What did that mean exactly. I thought the PCV would take care of all that fuel and ignition stuff.

I started cutting my exhausts down and gutting them. DSC_0035.JPG DSC_0028.JPG
 
ECU flash means interfacing with the ECU and writing a different fuel map on it. Those of us with 2011-2014 449/511 bikes had some very lean maps that came loaded from the factory. Tinken at Zip Ty figured out how to load a better map meant for use of the Euro standard bikes with the optional Akro exhaust. However, I believe your bike with the old big block 510 motor and uses the Mikuni injection instead of the Keihin system that this practice is often referring to.

Having a better base map on the ECU is an advantage using either the JD, or PCV. BOTH systems piggyback on the stock ECU and don't replace it.

If you mean in stock at fullmode/powerkit-up.
To me my husky dealer explained, when you but that bike in fullpower mode, it should show at that meter SEL2, that SEL1 one are for that limited power. But when you but that PCV it dosent matter what the meter show...

Ps, but if someone know more better that, could explained better, i dont know can trust what that Husqvarna dealer was talk about
 
I don't think mine says anything like that when I turn the bike on. But as you say the PC V will take care of that and get it all sorted.

I sent my shortened stock cans off to be anodized matte black, can't wait to hear and ride it without the choked up std mufflers
