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 The previous version was outdated and no longer supported.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

Trying to replace Mikuni with Keihin PWK. The PWK came off a YZ250, has TPS and power jet. Hooked up carb, leaving electrical unhooked. Idled OK, fouled plug when I hit mid-range. Did it twice, same result. There's gotta be something else I missed. Didn't do anything to stop up power jet. Is that the problem?
 
Did you remove the TPS plunger and other components? If so, that circuit will be in a constant open state and will always be delivering extra fuel.
If you didn't remove then the plunger will be constantly closed and there's no problem.

I learned all about this when I installed a TPS-equipped PWK36 on my CR.
