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 The previous version was outdated and no longer supported.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

"77" WR250 Jetting ?

Husqvarna
AA Class
I'm looking to put a 38mm Mikuni on my 77 wr250 (because that is what I have) and was wondering a good starting point for jetting. Any help or recommendations would be very much appreciated.

Thanks, John
 
Here's what I am running on my 78 250CR with a 38mm Mikuni
250 CR Jetting
Needle 6DH3
Slide 2.0
Main. 390
Pilot. 35
I'm at about 900 ft above sea level

Thanks Bill. This bike is coming from two parts bikes I bought. The seller only had this carb (38 mikuni) that had a tag on it that said husky. I don't think this was the one on the bike because the rubber boots I have only fit a Bing. I'm going to take it apart and see what's in it sometime this weekend.

If swapping from Bing to Mikuni you'll probably need a newer manifold and carb to airbox boot. My 76 250WR came with the Bing on it and as I remember we had a bitch of a time getting it Jetted for the tight single track that we used to run here in the northeast. The Mikuni worked much better for those conditions on my 78 CR.

Yes this jetting thing is all new to me. I have lots to learn. I do need new rubber boots on both ends. I found one that will work on the airbox end at Lowes. It fits tight and will need to be cut down in length, but it should work fine.

I took mine apart and found:
main. 410
pilot. 45
slide. 2.0
needle. 6DH20
Not sure about that needle, the numbers are so dang small. The fella I got it from also had a 360 and I think this was the carb for that bike. I'm still up in the air about using this carb, I was originally going to get a 36mm Mikuni. I've even heard of people putting 34mm carbs on to get better low end?
John
 
Bill, if I could ask, what size needle jet are you using for that needle (6DH3)??
Thanks, John
 
Thank you Vinskord. Looking at that mine my be close. I might just put mine on with what it has and see how things go?
