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 The previous version was outdated and no longer supported.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

1978 390 AMX clutch spring question

Auto Lover ...
I was stripping and checking the mainshaft on my 390 AMX tonight. The clutch springs fitted for 2nd, 3rd, and 4th are different.
2nd gear has green springs
3rd gear has red springs
4th gear has red springs.

I know they are different rates, but my question is ... are they suitable for enduro going ?

Is this the usual set-up ?

On the down side, 2nd and 3rd gear shoes are wasted :(
4th gear shoes cleaned up very nice with the hacksaw blade and are good to go.
The Teflon coated bushes seem good too.

Hi Grouty,
The red springs are part # 161255401 and are rated at 12 pounds
The green springs are part #161255402 and rated at 8 pounds
second and third gears standard springs are red 12lbs
Fourth gear standard spring is green 8lbs
Optional springs were part # 161255301 rated at 17 pounds and this one was plain no paint color. Also another optional spring was part # 161260201 and rated at 22.5 pounds and painted white.

For enduro riding I would run 2nd red, 3rd red and 4th green. On the 420 autos Husky used the plain colored spring on 3rd gear allowing 2nd gear to rev out higher. Hope this helps

Thanks Marty, I will swap the springs around this weekend.

Yes please Steve, if you don't mind. The ones fitted have worn down past the bottom of the grooves ! Even if I did re-cut them I think they would be too small.
