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 The previous version was outdated and no longer supported.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

All 2st TMXX bowl nut porting

All my VM mikuni, TM mikuni, all 3 Keihin PWK's and my PWM carb have small holes in the bowl nut, and small holes in the threaded boss at the bottom of the bowl to allow fuel into the bowl nut from the lowest level in the bowl. The TMXX on my CR has the holes in the bowl, and the nut has a small area between the threads and the oring where the holes would be, but there are no holes in it? Just wondering if anyone knew of the reason? Seems you would want to be able to use all the fuel in the bowl, and the threaded boss sits up quite a bit off the bottom of th e bowl?
 
Just guessing here, but,
Maybe it's just to allow any crud in the fuel to settle there rather than feed it into the engine?
 
Joe Chod here swears by drilling the holes and says it stops the fuel starvation when WFO on the 125. He has a lot of time on the 125 so I'm guessing he is on to something. Try it.
