  • 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 The previous version was outdated and no longer supported.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 started my 450 Sunday morning at home and it was fine. When I got to the track a few hours later and went to ride it....as soon as I turned the gas on it absolutely poured out of the drain hole. I think something is possibly wrong with the little drain screw. I've removed it numerous times and can't find any visible reason this is happening.

The allen screw seems to bottom out and I have about a thread or two left. It won't go in any further...and seems like it should be in far enough to block off the drain.

On the microfische there appears to be no orings or anything that work with this screw. When your guys screws are in all the way and functioning properly do you have any threads visible?
 
My drain screw has some visible threads if I remember right on the FCR carbs. Did you inspect the float? Sounds like something along that line if it is all of a sudden pumping gas into the carb and out the overflow.. Or is it coming out of the very bottom drain?
 
Odd.. I wonder if something got chewed up in there so the drain bolt doesnt seal all the way. Did you take the bowl all the way off and look at the drain/bolt/bolt hole closely? If not give it a thorough inside/out inspection
 
The drain screw is also an overflow, and it's the one fuel "should" start coming out first if the float were to stick. There's a tube on the inside that goes to the top of the float chamber and dumps fuel out that same hose if the level rises to that pooint.

If it were just the screw it should be more of a leak and not, "pouring out" like you say.
 
check your needle the to p lock cap on top of the slide may have loosened sounds like your nedle maybe stuck. examlpe fine when loaded dropped ou of truck just jarred enough the neddle may hang
