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 The previous version was outdated and no longer supported.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

430 dyno time

Right..dyno challenge eh! I will have to put the 400 on and we can see how the port job went in blowing off old aircooled engines.... Bugger! the local shop has flogged their dyno:( you win...
 
What size front sprocket? What mix ratio? How tall is your rear tire? You tire is shorter than a dirtbike tire with the knobbies. That's going to eat up rpm's.

Sounds like your needle jet is a tad rich? I'd shoot for the needle in the third slot then you have adjustment either way.

Blowing off ac engines? Lol. My '86 400 WRX what ever it was(said cross country on the swing arm) was very fast. She blew away a kx250. We tested the speed on the kx it topped out at 85mph. We figure the 400 was over 100 mph. I'm going to need another rear rim for a street bike tire.

Dyno's don't lie.
 
If anyone has the cycle worlds book on 75 to 86 Husqvarna I think it is. They say the 390cr has 43hp at the rear wheel.
On the full body dyno that's rear wheel hp. Now figure how much hp we lose through the gearing?
You might be near 50hp?
 
What is your reed block ? Is it a Mossbarger or stock?

And one more question do you know or can you get me what the
cylinder pressure is ?? Kick with PSI gage with trouble wide open.

Would really want to know this figure.
