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 The previous version was outdated and no longer supported.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

1983 wr 250 gearbox oil?

Yes, there is. Without wishing to open yet another oil debate ....
I have been using Silkolene Medium Gear Oil for the last 35 years, and I've never had a gearbox or clutch issue.
Everyone has their favorite.
 
Thanks. I have heard also that atf is used in the gearboxes.....I recall ATF in forks but is ATF a bit light for gearbox?
 
In my experience, using ATF in straight cut motorcycle trans results in quite a bit of visible metal in the oil... Several years ago I contacted Maxima Oil... they sell ATF and wet clutch gear oils and they told me due to the popularity of racers using ATF they tested both side-by-side in their Supercross team bikes and measured significantly more trans wear with ATF. Their ATF was the more expensive product but they recommended not using it and using their MTL line of gear oils. They said that straight cut motorcycle trans gear teeth are narrow and highly loaded compared to planetary and helical automotive trans gears and the motorcycle trans has different lubrication requirements ATF can't meet.

That said, many swear by ATF and I think KTM specifies it in some of their new bikes. :excuseme:

Then I found the original letter I received from Malcolm Smith Motorcycles with my new Husky several decades ago and they recommended Torco gear oil... I've been using Torco MTF-L since and have been very happy with it.

Note that the SAE uses two completely different rating scales for motor and gear oils... a 75w gear oil is equivalent to a light weight motor oil.... Maxima says their 75w is approximately 10w-30... I think Torco told me their MTF-L is equivalent to 20 weight motor oil but I don't remember for sure... it's what they recommended. The Torco stopped the cold "clutch drag" completely.
 
ive been using briggs and stratton oil in the 400 lc, no probs, great clutch action...have used Atf F as well with good results...the trick with ATF is to change it regularily
