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 The previous version was outdated and no longer supported.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

Hi everyone! I got my Keihin from Kelly at Motosportz yesterday after ordering it last week! Good and fast service! I just mounted it on my WR 300 with the JD kit in it. It was a tight fit and the airbox rubber is pushed backwards a bit, but i guess that shouldn´t be any problems with that. Okej, so to the drivingtest then. The carb was jetted as follows: 45 pilotjet, JD blue needle in 3rd clip position, 175 mainjet and airscrew 2 turns out. Rolled it out and kicked it two times and it started fine. Turned the idlescrew in quite a bit and then it idled perfectly. Then i went off. I immediately noticed the difference compared to the Mikuni. It´s more "direct" on the throttle now. Definately more power at low revs. It wheelies easier in second gear now then before. (i have 14/42 gearing with my Motardwheels on=). The only thing that needs to be fixed is the very light throttle bludder. When i go streetdriving i use very small throttleopenings and it´s "4-stroking" as we say here. I maybe should try to lower the needle one clip and see if that helps? We have about 50F here now and i live at sealevel. What do you guys think? I also would like to know in which way the red needle is different.
Thanks!

I do not know about the needle, but that is the same pilot and main that I am using in 2 WR250's, both with Keihin carbs.
 
If you're below 1/4 throttle then the fuel is primarily flowing through the pilot jet. I think the needle jet and pillot jet overlap between 1/4 and 3/8 throttle, so depending where the blubber is it could be either or a combination of both.

If its blubbering and choking on fuel then its sounds like you're on the rich side and you'd want to raise the needle clip. If it feels like its not pulling enough fuel and surging then you're lean. Sometimes its hard to tell what you're feeling and its even harder to describe it, so trail and error is the best tool.

When experimenting, always try a richer setting first so you wont risk doing engine damage by going from lean to leaner
