• 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 The previous version was outdated and no longer supported.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'm stumped on the idle circuit on the PHF36 on my 2000 TE-410. Stock jetting according to the manual should be a 170 main and a 60 pilot. That's exactly what I found when I opened it up.

Here is my tuning procedure. Warm up bike. Turn up idle with adjustment screw. Back out mix screw unyil the engine reaches maximum RPM. Turn idle down a bit and make fine adjustments to mix screw. Adjust idle to normal idle RPM. When tuning the mixture screw, I have to open it up 5+ turns. I bought some additional pilot sizes, and even with a 66 pilot, I have to back out the mix screw to 5 turns.

I checked in the carb body, no washers or o-rings stuck in there. I even bought a complete new mixture screw from Guzzino.com, thinking there may be an issue with mine. The one I received was a very different profile and wouldn't even begin to thread in.

Any help or advice or help is greatly appreciated.
