• Husqvarna Motorcycles Made In Sweden - About 1988 and older

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 The previous version was outdated and no longer supported.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

Been working on my 72' WR250 w/Mikuni 34mm, it had some air leaks etc. I have all that cured and it runs good except a little bog just off idle but only when hot. Let it sit a little and no bog. I think changing the pilot jet would help but which way, larger or smaller? Any other ideas? Seems to be fine once on the needle and main jet. Plug is chocolate brown
 
For a 0 to 1/8th throttle bog you're on the right track with fixing air leaks and considering the pilot jet. Make sure pilot jet is clean as well as the tiny circuit from the pilot to the venturi. Use a stiff bristle from a wire brush and compressed air to clean.

Keep in mind that the air mix screw should be about 1-1/4 to 1-3/4 turns from the bottom. If it will not rev smoothly at this adjustment then try a pilot the next size or two larger.
 
Had a 45 pilot, went and got a 50, 52.5 & 60 going to try the 52.5 first. Carb is clean
 
im thinking its rich off the pilot as its only when its hot that it bogs. cooling down and it likes a bit more fuel. maybe a bigger cutaway to let a little more air of idle:thinking: . try the 52.5 and if its all blubby then you should know where your at
 
Where does the balance screw end up turn wise? Sometimes it can be so far off it may take two or three try's to get the balance right. We end up balancing it, turning the idle down, balance it again, maybe change the jet if the balance screw isn't within the specs.
With a bog off idle try pulling the needle up one slot to see if it's a lean or rich bog. If it responds better it's a lean bog.
 
Alright, I put the 52.5 in, seems to have cured the bog so far, air screw 1&1/2 turns out. Running pretty freekin good now, hoping to be done so I can blue locktite everything, had it apart a dozen times LOL.
