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 The previous version was outdated and no longer supported.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

Trans oil for a "77"

Now please forgive me as I don't really want to open a can of worms here because I know everybody has their opinion and I have read a number of threads. My manual says to use S.A.E.20W, I know the manual is 45 years old and oils have come a long way since then. When I raced these bikes in the mid to late 70's I seem to remember always using Non Detergent oil in the transmission and the front forks, and we changed the oil often (after every event) and never had any problems.
Is this still a viable option?? I've been told just to use Spectro or Belray 80W gear oil and you don't have to change it that often?
The manual states S.A.E.20W and makes no mention of Non Detergent but I'm 99% sure we always used the non detergent. I do plan to race in some vintage hare scrambles. Does anybody use the old school oils or are most using the new gear oils???

Thanks, John
 
20w is a viscosity number
a ball falling through oil at a fixed temperature
modern oils stay in those viscosities
as stated above MTFL 75w is measured differently but is an old school 20w if that makes sense
don't get bogged down in brand names, pure synthetic can last longer depending on your riding
check it regular and change when dirty

2premo, so that being said, it would be ok to use a full synthetic multi grade motor oil (say 20-30)?? Or use a 80-90 grade gear oil? I do understand that a 20W motor oil is about the same as a 80W gear oil.
Thank you for the reply
