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 The previous version was outdated and no longer supported.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

Running on when hot

AA Class
79 250 OR carburates great from idle, part throttle, and full throttle but when hot it runs at very high idle and if I miss a shift the engine is screaming. When I stop it takes time for the idle to settle down. I am thinking float/needle seat issue. It is sometimes hard to start due to wet plug also. Any ideas. Plug color is absolutely perfect. I have tried the air screw in and out but no luck.
 
engine seals leaking when hot? split in the inlet manifold? my bike used to run on after landing from a jump or dropping the front wheel down hard as the split in the lower half of the manifold would open letting in a heap of air. took a while to figure it out as it was split on the step up and very hard to see.
 
The pilot was 2 sizes smaller than stock. I went up one to a 40 and man it starts, idles and revs much more freely. I have not ridden it yet but I suspect that it should be much better. I also lowered the float level allittle.
 
Well it is not fixed. I raced it this weekend and still running fast. It starts and off idle is awsome. I think I need to look at the intake when the engine is hot.
 
Do a leak down test to find out exactly where the leak is. I am just making a tester now, so I'll post some pictures when I have all the bits together. If you just start replacing stuff at random you will never know for sure. The favourite is always the stator side seal as PawPaw said above. But it could be something else.
I have seen Motion Pro sell a kit for $189 plus shipping (to the UK it is expensive). I reckon I can make mine for $20
