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 The previous version was outdated and no longer supported.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

Last question about 400 enduro (sorry)

The pilot jet was clogged, but the bike still wont idle :*(

It did seem to run way better when i drove it though

Also it will sometimes full rev when im trying to adjust the idle

You can't always get the small holes in the pilot cleaned out. Many folks replace with new.

Man, that's just not making any sense to me. Full rev when turning the adjustment screw..huh. Without touching anything else, you can turn that thing one full revolution and maybe gain at most 1000 rpms...but that sure isn't full rev unless your definition is different than mine. To me, "full rev" is OMG, SHE'S GONNA BLOW!!! Are you sure your cable is running free and not binding up when you twist the throttle (assuming you're twisting the throttle when the full-rev happens)?

Me either. It was the omg shes gonna blow feeling. I think the cable was binded so i loosened the crap out of it. I know i must seem like an idiot but this bike is driving me crazy. Still though it didnt make sense to me since i could rev it all day until adjusting it. Im thinking it HAS to be an air leak.

the manifolds on these are antique and rubber, try moving the carb while it's idling, if it revs buy a new manifold
the aftermarket and late Husky as in 88 and replacement parts were a 2 piece design with an aluminum base and a rubber carb mount
 
Sorry its been freezing/snowing and I only have a shed to work on it. I did sprayed it and nothing changed. I took off the intake manifold and has a deep crack on the inside so im thinking maybe the fuel is getting caught in it or something. So I think im gonna replace it.

Also I was really frustrated lol.
 
If it were mine I'd do a leak down test. Crank seal or gasket could be leaking which would create a lean condition at an idle. If you're not familiar with how to do a leak down test check it out on Youtube.

The crack is real deep on the inside, but the outside isnt cracked, its sealed. Its not leaking out, so could the crack itself fuck it up? It kind of looks like when a road splits, not just a crack, but its open.

I'll check it out thanks
 
The important is not because the spring looks to be too heavy but because maybe it is too long. If its too long the screw doesnt work at all.
Please try without any spring and see what happens.
 
that will be your trouble, it may seem ok but it will be leaking in somewhere. as the intake vacuum builds, it opens the air leak and everything suddenly changes and the motor stops. if it opens it slowly, you get a gradual leaning (like the fuel is turned off) and it starts to rev for no reason. sound familiar??? heh?

Of to SUDCO you go young man and get a new manifold. (google them and all will be revealed)
