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 The previous version was outdated and no longer supported.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

Chain recommendations for '82 430 XC

This project bike came without a chain. I just it back together and am hoping one of you knowledgeable folks could tell me what size chain, and how many links. Back sprocket is 56 teeth, and front is 13 or 14? Thanks in advance. This bike will be for sale as soon as I get the chain on it. mojorules@gmail.com

It is a 520 chain that means five eighths inch pin to pin and two eighths thick sprockets. If you see a third digit it often references the roller diameter being other than "normal". No industrial equivelant for that one though an industrial 50 would sort of work just 3 eights wide sprockets. I generally either buy a new length 120 links long and cut it as needed. I like rivet on master links. In the past I have just used used chains with master links and cutting as needed. Exactly how high quality you want to go effects the choice. Chances a normal used dirt bike chain with say a 48 or so rear sprocket wouldn't be long enough. Generally it is best to replace the chain and the sprockets at the same time. 56 is pretty big unless there is some logic to it.

Are you sort of looking to buy some chain or sort of trying to sell the bike?
 
The sprockets are in decent shape. My guess is that the chain was rusted and the previous owner removed. I don't know why the bike has a 56 tooth sprocket or that it wasn't stock. So you're saying that a 48 tooth is stock? And yes I'm selling the bike but will put a o-ring chain on it.
 
I am saying 48 is kind of average for modern bikes which you could get a used one from real cheap. With some effort you could find out what it came with in the reference section here. Just guessing 53 or so would be origional. Not sure how much it really matters but let's say you have a 14 front then you don't want to use a 56 rear because 14 times four equals 56. I have looked through origional ratios and that didn't happen from what I saw.
 
The bikes had really tall gearing inside the engine, so they used a really low sprocket ratio, like 13/53. 13's don't last very long so it was pretty common for guys to go to a 56 rear and up to a 14 in front for a little better wear. The ratios are very similar (4.07 vs 4).
