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 The previous version was outdated and no longer supported.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

74 mag with Femsa Ignition

Hi all- I just got a 74 mag barn find- bad top end. All the numbers match the Mag specs
I believe this was professionally turned into an enduro (big sprocket- brake switch-crank stub for a Femsa ignition).
Has anybody seen the Femsa done? I'm tempted to leave well enough alone.
any thoughts?
thanks- Rob
 
I have a similar Femsa on my 349 Montesa Cota. You can get points from Hugh's Bultaco or Hogans Cycle in Agawam MA. You can find a GM cross reference for the condenser. Points won't leave you stuck like a failed CDI can. Always could clean a set of points with a match striker in an emergency

Thanks- I like points- cheap and easy! I know there's a joke somewhere.
 
90% of my Huskys have had a Femsa ignition and like jimspac said points are far less likely to leave you stranded. I found that due to wear on points you need to be accurate when setting the timing if you like your Husky to fire up within a couple kicks. I started using a buzz box to tell me when the points were beginning to open since my eye sight is now 57 years old, the buzz box helped a lot.

Since I move slower these days and have more patience I also use a dial indicator to accurately set the timing Before Top Dead Center as recommended by the factory. Its amazing the difference when kick starting a bike especially a big bore.

For a while, when I young and crazy, I rode a 600 Husaberg FC. It was the fastest and most difficult bike to start that I ever had. Using a dial indicator I retarded and advanced the timing from the recommended factory setting one degree at a time until the thing would light up on the first couple kicks (no more back firing too). I don't remember how much different the timing ended up being over the factory but it was great to ride that rocket ship and be able to kick start it too.
 
Perhaps the most critical issue with the Femsa is making sure the "cam" face on the external rotor is not pitted or rusty.
Clean and smooth, with a THIN wipe of high-temp grease.
If it is pitted, it will chew up the points arm end quickly...closing the gap...eventually no spark.
 
I have a '76 250WR which is nothing more than a Mag engine with a wide ratio transmission and a Femsa ignition. I really like the power delivery with that big flywheel, it will chug down to zero RPM like a trials bike, but once it comes on the pipe its just as fast as a CR. You get the best of both worlds.
