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 The previous version was outdated and no longer supported.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

1987 overflow bottle

Hello all
My ´87 430 auto has a radiator overflow bottle mounted on the front down tube between the radiators. I don´t know if it a standard item or after market - did they ever come as standard?

This bottle has a couple of small pop-off valves in the cap effectively giving me two radiator caps and I am concerned because coolant is being forced out around the pump housing when it gets hot. I suspect that the bottle is causing the system to become over-pressurized.

A couple of local people who are very familiar with the later Huskys have never heard of over flow bottles being installed.

Any info is welcome
 
I had that bottle on an 86 auto. It boiled over in a normal fashion (twice basically no air through the radiatios type of scenario) without blowing coolant out at the waer pump. Sorry I never paid any attention to pop off valves in the cap. Did you try and find an auto parts supplement document? I bought another one off ebay also supposedly from an auto. It does complicate running the wire from the ignition to the coil and the clutch cable and might restrict the inward motion of the radiators in a crash.
 
Thanks.
I might try removing the second set of valves (in the bottle cap). When I first got the bike they were not installed and I had not problems. I don´t remember when I installed them but I have been having this problem lately. I wonder if this bottle is for a bike that does not have a pressuring radiator cap - all other engines I have seen just have a normal radiator cap and the overflow bottle only has a breather hole.

The radiator cap is the same as all of the other 85-88 two strokes I have seen. Of course I bought it used. The four stroke one I have is smaller. If you work at it you probably can find pdf files of the parts sheets of various bikes and the auto supplements in the teck reference section on here. I put the overflow from the radiator into the bottom and leave the top tube open. You have me wondering if there are valves in my covers. Silly pick up truck doesn't even havel a radiator cap per say just a pressurized overflow plastic or nylon tank. If you find a different part # for the radiator cap auto vs six speed post back.
