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 The previous version was outdated and no longer supported.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

I'D like to fire up my 71 400 cross . It's been sitting in storage for 18yr. Has spark end good compression , I'm concerned about the crank seals. This bike is 100% original and sure don't want to damage anything.
 
Good news, the crank seal on the ignition side can be changed easily. If you start the bike and the engine rpm starts to rise with the throttle closed, this seal is sucking air (leaking).

Bad news, if the engine runs fairly well but smokes excessively, the primary side seal is leaking allowing transmission oil to be sucked into the crankcase. The primary side seal requires splitting the cases to replace.
 
Looks like bad news here for me...pulled my 125 WR out of 11 year storage yesterday to prep it for a vintage CC race...

Started on the 3 rd kick...but smokes and fouls plug with a greyish goo after a few moments.
My only thought is it must be a leaking clutch-side seal.
Trans/clutch has fresh Type F ATF (which is red)...previously had 20 wt motor oil in since rebuild back in 2003 for MA ISDT Reunion ride, which was the last time the bike had run.

Any other suggestions?
 
try flushing the motor with some fresh fuel, may have a settled pile of oil on the bottom of the crank...
 
A good suggestion...after a flush I've now got it running clean at half and full throttle.
Now if I can just clean up the low speed revs and idle.

Thanks
