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 The previous version was outdated and no longer supported.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

Any recommendations on black paint that will stick to the Mag engine? It seems like everything I try comes off the magnesium parts. I have also heard that additional paint on the cylinder or cylinder head impedes air cooling. Any truth to that?
 
I find that Rustoleum semi gloss black engine paint works well on magnesium engine cases after priming with the recommended primer. It is important to not touch anything with bare fingers before spraying and wearing surgical type gloves through out the prep process will ensure best results. Magnesium is especially sensitive to contamination, even more so than aluminum. If you want to paint the fins, you will find it among the world's greatest PITAs after cleaning the fins enough then getting the paint in evenly

After paint cures, a light polish on the cases with very fine grade scotchbrite will yield an OEM like finish.

Excellent! Thanks for the info. I'm having the most problems getting paint to stick on the cases just below the carb where gas drips when I tickle the Bing. Maybe priming it before going with the black paint will work. Should I prep the case with anything other than soap and water before priming? Also, is the silver Rustoleum primer the one to go with? Sounds like I should just leave the top end alone - it doesn't look too bad anyway.
 
I use cal-gaurd gun coat paint with their adhesion promoter.If you do the correct prep and post bake, as tough as the original black.If you can blast cases with 000 sand that has given me the best results.
 
When you guys mention prep, are you talking about doing something besides soap and water? Maybe removing old loose paint with steel wool or a scotchbrite pad?
 
Yeah i try and remove everything i can as you have to paint on fairly thick to make the job uniform.
Best to with fine sand paper blend the edges in, degrease the job with jizer, gunk or swarfega de greaser then hot soapy water it off let it get flaky stuff off with your prefered method wire sheep or desert paper then degrease the whole lot again, i use etch primer and radiator paint as my cases are silver.
Then jobs a good un.
If the missus is out and the cases are split i chuck em in the oven for an hour at 50-80c gentlly bake the sucker on. Hard as nails afterwards.
 
I would clean bare magnesium with acetone for the reasons stated in my above post. I used Rustoleum engine primer. The system I used on engine cases works on triple clamps as well
 
Thanks guys! Just had the frame powder coated, rebuilt the top end, got new crank seals, a PVL ignition system - all she needs is for her cases to look pretty now. At least until I put her through some Florida mud...
