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 The previous version was outdated and no longer supported.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

OK. Ever since I restored my 74 250 mag, I have only successfully kickstarted the bike maybe twice. Luckily, my driveway is on a 45 degree angle, so whenever i wanted to ride it...i simply rolled down the hill and bumped it. Always started right up and ran like a champ. I was riding around the neighborhood a couple weeks ago. Bike was running for a good 45 minutes. Stopped at a stop sign, and motor went dead. After several attempts at restarting by running it down the road and popping the clutch, no luck. Walked it home, and after some checking, I had zero spark. Upon pulling the flywheeel, the motoplat stator appeared as though it had gotten extremely hot and after testing, checked to be bad. My dad was able to borrow a functional stator and coil from Stahl down the road. Upon putting his system on the bike, obviously, I had spark again, but not a whole lot! seemed weak and somewhat intermittent. (like it was before hence the no kickstarting issue). Also in the box that my dad borrowed was a flywheel that went with the system, but the tapered hub was cracked, but for the hell of it, i threw that flywheel on ad hand tightened the nut......... Amazingly hot blue spark**************************************** This sounds really odd, but how can a flywheel make a difference? Could there be a difference in the amount of magnetism??? Both of the flywheel ID's check the same within a few thousandths of an inch, and both seems to be considerably magnetic...(IM stumped)

PART 2:

In the realization that I would either be sending my stator out for a $200 repair, or purchasing a complete replacement ignition, i decided that I will probably just buy a replacement ignition. Therefore, for the heck of it, decided to mess around with my motoplat stator, knowing I could potentialy ruin any chance for someone else to be able to repair it! I used a heat gun and started heating up the bakelite-type plastic in small spots, which made the plastic peel/chip off with ease. After a half hour or so, I was left with a completely exposed stator and all of the plastic was off. All of the coils (physically) looked OK. What I did find was the black wire that is connected to the trigger was broken off. Under a magnifying lamp, there was still a VERY SMALL wire still exposed from the trigger, and i was able to tag the wire back onto the black wire and effectively solder them back together. My stator now checks 18 ohms between black and blue leads, and 320 ohms between Blue and ground. The 320 ohm check is high based on the figures I have been able to find on the internet, but upon throwing it back on the bike, the stator now produces spark which seems weak and only with a hard kick with my flywheel (as it always did), but strong and blue even at low RPM using the borrowed flywheel !!!

I guess through all of this jibberish, Even though I'm getting spark with my repaired stator, does my high reading on the blue to ground check mean that my stator is going bad or is weak? It now seems that my problem all along with the no kickstart/bump start only has been with the flywheel? In all of my dealings with bikes, I would have laughed at someone if they told me my flywheel was bad. Can I replace it with any mini-6 flywheel with the same crank taper? Can my flywheel be remagnetized or repaired? In the end, I am extremely happy that my stator is now working, but will be even happier if I can kickstart this thing simply by changing out the flywheel!
 
At 320 its on its way out, I have one at 364 and will run for about 15min or after it heats up ,but then again I have one at 190 that will only run at 5000 rpm and above . Yes you can remagnetize the fly-wheel and any with the same taper will work. should feel like about 6 to 10 lbs of force to pull the stator and fly wheel apart. Do you have coil with red spark plug wire and stator wire with red wire lead caps?

I can borrow a gauss meter from work today and do a comparison check between the flywheel that sparks good and mine. Yes..the stator does have the red insulators, and my HT coil is the Red lead with the diode. Would remagnetizing the flywheel require special equipment, or would magging it down on an electromagnetic chuck on a surface grinder or something similar work?
 
I have some flywheels or penton racing products who sells the PVL's does remagnetizing I was told .
 
Yes, I have built a remag set up for my MotoPlat flywheel. It's the same principle as the old high school experiment where you magnetized a nail.
I made a loom using a old jug and sandwiched it between two pieces of plywood to hold the wire on it.

The rotor sits inside and I hooked up the ends of the wire to my dc battery charger (takes more wire on 12v than 6v or it will overheat). You have to switch the leads after about an hour so as to remag both poles on the magnets.
This is from another site. I have never done it, but I know this person and he is pretty sharp.
