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 The previous version was outdated and no longer supported.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

Does anybody know the stock setting for the fuel screw?

I looked in the manual and see 1-1/2 turns for the "Idle Mixture Screw" I believe it said. Does that refer to the idle adjustment or to the fuel screw?

About a year ago I took out the stock and replaced w/an adjustable fuel screw. I think I checked the stock and it was 1-1/2 so that is what I have the adjustable set to.
 
I believe that would be the fuel screw referred to in manual, "stock" setting being 1 1/2 turns out from full in.
But altitude and temperature affect it, so that may not be the ideal setting at your ride location/conditions.

When you get to your ride and have warmed up the bike good, you want to turn that adjustable fuel screw in or out, to where you get the best idle at location where you will be riding........I may ride in temps from below freezing to triple digits, and elevations from 2000ft to 9,000+ ft and always start each ride after the bike has warmed up, by slowly turning fuel screw in until idle starts to die down slightly, then slowly back out until I get the best/fastest idle. (maybe about 1/2 turn or so) And I may adjust it thru-out the day depending on how things change
If jetted right, you should typically be in the range of 1 1/2 to 2 1/2 turns out.
 
Thanks, RLW. I've never adjusted it past the initial setting of it. I'll give it a try next time I go out.
 
Hello
some carburators are easier to tune the air mixture if you bring it just off idle and find the mid point with the air screw.
1500-2000 rpm constant,adjust the screw until the revs drop.then turn the srew the other direction until the rpm climbs.
park the screw in the middle.
