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 The previous version was outdated and no longer supported.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

Fork Oil or Magura Blood for clutch fluid?

My bike still has the factory clutch fluid. I didnt want to change it because in the 10 years I've never once had issues with my master or slave cylinder, like many of you report, and I was worried that if I mess with it, I'm going to have issues. But now it's been 10 years, and I really though I ought to..

The Factory service manual says to use fork oil, but does not state weight. Magura says to never use anything other than their Magura Blood mineral oil. Which do I use? I've never had good luck with Magura Blood in the HyMec systems on my other bikes. On my other bikes, once the slave heats up from engine heat, it thins out the Magura Blood so much that it lets in a tiny amount of air (assuming by the master's piston?) and over time it accumulates to where I have to bleed my clutch probably every 2 months. On my Husky, I've never once needed to bleed the clutch in the 10 years. I don't know if this is attributed to the factory using (thicker?) fork oil, or the slave is just a better design than the HyMec slave on my other bikes.

Let me know what you guys run, and if it's fork oil, then what weight?
 
Just bled mine and used Maxima fork oil 10w, seems to be working fine. Dont have any long term info though
 
I have used motul mineral oil with good luck. You can use atf or if you really want to save some money, singer sewing machine oil works. Can be bought for $3 at most stores. Personally I’ve never tried fork oil. When back bleeding the slave cylinder, I’ve always found it easiest to disconnect the line where it connects to the the master cylinder until you have no air, then reconnect and continue bleeding. I would always get a spongy feel in the lever unless I did it this way.
