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 The previous version was outdated and no longer supported.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

How a carburetor works.

I get a lot of questions about jetting.

In the past I've given some simplified info on how a carburetor works and what circuit affects a given TO.

Here's a visual aid to same that may help some riders DIY.
No AP circuit is addressed here as all that does is cover the hole one makes by whacking open the throttle on a 4-stroke bike and same has no affect on constant circuit metering at a given TO.

This visual aid can help one with an issue they may be having at a given TO. It is not for diagnosing a "problem".
(i.e.: mech issues, cloggage etc. You cannot jet around same and those must be corrected first.)

Also- "rule of thumb" to a certain degree:
Bog/stumble- lean
Gurgle/blubber- rich

A: AS and PJ
B: Nozzle
C: Needle
D: Cutaway
E: MJ
