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 The previous version was outdated and no longer supported.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

390 Frame swop?

Hey everyone, I want to put my 1979 OR390 into a CR`77 -`78 frame, is this possible? can I use forks and rear shocks from my `79?

Thanks!!!
 
You would need to convert the triples to ball and cone or find someone to make you a set of Timken cups for the steering stem. Or come up with a 1977CR triple clamp set. The shocks may be a little too long for the ML frame but I have seen 16" Gas Curnutts on them.
 
Thanks for that info, think it be easier if I wait for a `79 frame to come along. How much does the steering improve between CR and OR as far as turning in quicker?
 
The main benefit you would get from the ML frame is sharper turning. 29° rake for 77 CR and later ML frame vs 30.5 rake for 1978 OR and all 1979 MM frames. I have a collection of ML frames for a few selected builds I am doing. Just for that tighter rake angle. I will check to see if I still have a ball and cone offset 35mm triple set left. I sold one and I likely still have one on hand
 
I can possibly make your Curnutts shorter to fit the earlier frame. The 78 OR had 16" Curnutts and the 79 had I believe16 3/4 inch shocks. I am too lazy to go out and measure a set but I can make the longer shock work.
 
Two things I forgot to mention is im running with 40mm forks , would make it more difficult to fit the earlier frame? also have a pair of recently refurbished ohlins fitted , id prefer to leave these as they are if it does not cause any issues?
 
You would still need Timken cups to use the 40mm front end on your frame. I got mine from harvesting from a trash 1978 ML frame. If not for that I would have had to make them. Unless you can adapt the triples to use the cones off the old triples. The stems I believe may be identical
 
Thank you for that Jim, just need to pick up a frame in the next few weeks, a winter project I think.
Cheers!
 
You may be able to convert the 40mm to ball and cone to get you thru. You have nothing to lose by trying anyway.
