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 The previous version was outdated and no longer supported.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

Hello to all.I picked up a 73 cr 250 that has the weakest spark I have ever seen.After testing it with my meter the stator & coil show some what close to the specs that are posted on several motoplat web sites. I have noticed that neither part shows it contains the required diode.I am thinking someone swapped the coil with the wrong one.Can someone chime in & tell me what circuit has the diode.Nowere on the net is it shown. If I knew where it goes I would try a few different ones I have. Thanks, tom
 
As part of the process of elimination. Make sure you have good ground eveywhere. Motor to frame, coil to frame and stator plate to motor. Poor grounds can cause a weak spark.
Try disconnecting the kill button to.
 
Look at the service bullitens and/or the Husqvarna Reports in the Vintage Tech Ref section. I think the infomation you are looking for is in there. The one about updating the black wire coil. I think it says something about the diode being moved to/or from the coil. Lot's of good infomation in there.
 
Tommie D is right, change the coil out with a 77 or newer coil, and make sure its grounded well, and youll see great spark.
the 73,s had an issue with the upper coil, they pig tail grounded it and it still had issues...
updating to the newere style coil, cures the issue.
 
ok guys thanks for chiming in.I went through all the service bullitens on this site & was unable to find what I need.I did check the stator ground to frame & coil. This weekend I will clean all posible grounding & try a jumper between the stator & coil.Also going to try a diode on the black lead at the coil.Worse case I'll have to spend the big bucks on ebay for a coil.I am allso thinking about a possable jap bike cdi transplant if I cant get the motoplat working right.Ill keep ya posted,thanks,Tom south florida
 
If interested in running the motoplat have Vance rework it - he does wonders. Ron also has a good suggestion also - PVL work well on the smaller bores.
