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 The previous version was outdated and no longer supported.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

.............has anyone mated a 500cc water cooled top end onto a 430ccAE water cooled bottom end?

Am i right in thinking i would have to change the rod to a 500cc, is there any machine work involved.
 
Not much into water cooled Husky's, But, on say the air cooled 83's the 430 and 500 share the same engine cases. 10mm longer stroke on the 500, so if the water cooled bikes followed the same path then yes change the rod and the cylinder studs. No machine work I can think of.
 
Thanks Tommie, thats what i was thinking, as the 430 and 500 piston sizes are almost the same it had to be in the stroke.

Cheers
 
hi, you're gonna have to machine a slot in the end of the crank for the water pump drive and get the side case with the water pump in it. yes it has been done.
 
I looked into doing this a while ago . I think that there is a bit more to it than fitting a 500 rod & cylinder studs , although the stud pattern is the same & the 500 cylinder will fit . To get the extra 10mm stroke, the big-end pin has been moved 5mm further out in the crank webs on the 500 . It would be easier to use a crankshaft from an air-cooled AE500 & replace the left side half shaft with one from a 430AE (with the slot for the waterpump drive in it) . The AE500 left crank half-shaft is about 20mm longer than the 430AE, so you can't just machine a slot in the end of it . The 500 also has a longer skirt on the piston.
