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 The previous version was outdated and no longer supported.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

250-500cc PWK Airstriker idle question

Husqvarna
AA Class
I just switched over to a JD Jetting pre-jetted Keihin PWK Airstriker 38 carb for my 2009 Husqvarna WR300 two-stroke. I am having trouble adjusting the idle. The bike is hard to start now, but starts easily if I open the throttle. Once it is started, it needs the idle adjusted. I followed the air screw adjustment instructions (starting out 1 and 1/2 turns out from seated), but it didn't seem to make a difference (it is hard to tell whether screwing it in or out makes a difference since the bike does not want to idle anyway). It there throttle position setting or something? The JD Jetting instructions only talk about the air screw, and jetting. What does the black screw handle do that is just above the air screw and fuel inlet (it is black with a spring on it)? Please help. Thanks. -Todd

PS: The bike seemed to be jetted pretty well on my short ride (mid and top end), other than the idle adjustments. I can make the bike idle by cracking the throttle and holding it slightly open.
 
Svttodd, That screw adjusts the idle speed. It sounds like it's screwed out too far and therefor not allowing the engine to idle. Screwing it in lifts the slide just the same as turning the throttle does. Try screwing it in until the bike idles. Then adjust the airscrew.
