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 The previous version was outdated and no longer supported.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

So after I reinstalled the JD jetting unit on my handlebars when I fired it up I noticed a few tiny drops of liquid on my speedo screen. Since I had just reinstalled the fuel tank I thought maybe I had left a fuel line off or loose. Ruled that out, cleaned off the speedo. Thought it was an anomaly and rode the bike. On the ride I didn't notice anything out of the ordinary.

When I got home I decided to troubleshoot some more and found out it is the clutch fluid coming out of the reservoir. It seems to happen when the injectors are priming before start-up.

I discovered the fluid is coming out of a tiny hole on the cap of the reservoir (see pictures).

Is fluid ever supposed to come out of the reservoir? Is the reservoir cap supposed to have that little hole in it? My brain tells me no because I can't imagine air getting into any hydraulic system is a good thing. But I have never had a hydraulic clutch and I couldn't find any pictures of the clutch unit from the correct angle to see if they all have that hole or not.

If this hole is bad news and not supposed to be there is the bike rideable to the dealer or should I take it in my truck?

Thanks in advance!clutch reservoir.JPGclutch reservoir closeup circle.JPG
 
I checked mine out, it also has a tny little hole like yours !
I think maybe Once I had strange drops on the speedo a goodly while back, but never again.
Looks like a casting fault on the lid to me.
Open the reservoir cover and check it out.
Maybe close the hole yourself if it does not look like it needs to be there.
Maybe be there is a pressure build up in the clutch system for some reason.
Don't know didly about hydraulic clutches myself.
 
That's a vent hole. It's supposed to be there. I have had two master cylinders and it was present on both.

Open up the cover and I bet your reservoir is overfilled. Take some fluid out so the reservoir is about half empty (half full? :)). Button it back up and the leak should stop. Don't over tighten the cap.
 
It needs a vent so it doesn't build pressure and self apply the clutch when the fluid gets hot. or create a vacuum when it cools
