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 The previous version was outdated and no longer supported.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

1980 WR 390 tips and advice

Went out and ran the bike and it almost sounds more like a rattle/ratchet sound than a knock. It doesn't go away with the clutch pulled but seems to go away when you rev up but its hard to tell if its just to quite to hear over the exhaust. I also tried listening with a rod on the engine to see if i could find just where it comes from but it is really hard to tell, when you stand next to it it sounds like the top end but when you put a rod on it its almost more like the bottom. Here is a short video i made of it running
 
Thats what i was thinking, that or maybe a wristpin. The only thing is it doesnt necessarily seem to be the top end, i need to get a mechanics stethoscope to be sure. I have the most expriance with truck engines and large marine diesels and all the bikes iv had didnt have any engine problems so i figured i would ask here for advice before i tear it down. I actually planned on stripping the bike down to the frame this winter to rebuild the motor and bring it back to mint condition so its not a huge deal but i had really hoped to do a little bit of riding before then.
 
I pulled the head a little bit ago and i defiantly have excessive play in the piston, so im going to just go ahead and do a top and bottom rebuild, and while im at it see if there are any other issues hiding in there somewhere. I already have a few questions about this but im going to make a new thread specific to the engine work.
 
I wouldnt do the bottom end unless you are positive it needs work, Huskys are extremely durable made with high quality parts, it is not easy to find bearings today as good as the ones that came in the bike. A top end is quick and easy, do that first and ride it.
 
I'm not sure yet if the bottom is truly in need at this point. My plan is to check for play once i take the piston off a little later. If it is still good i might wait on it, i just would hate to have it apart to do the top then have the bottom go shortly after.
