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 The previous version was outdated and no longer supported.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

250-500cc Power Valve Bushings Loose?

I had my cylinder replated again & when I got it back the brass PRV bushings are loose. When I got it back last time, I had to freeze them before I could push them back into place. Now they are loose & slide in & out easy. Did they remove too much material from the head when they blasted it? I don't want to waste $40 on new ones if they're the same size. Can I use a little dab of epoxy to keep them in place?

I had the same thing - I used a smear of JB Weld - worked great. I checked a lot of adhesvive properties when I did it, and if I remember correctly the JB fit the bill.

I have 2 WR's an 04 and 11. When I changed them on the 04 (which had worn bores) I ordered them from McMaster and used the JB. When I changed them on the 11 I did the same thing. The bushings from McMaster are listed as the same size but they got stuck in the bore of the newer cylinder and were hard to get out. Also the valve would not turn in the bushing. A big mess - so order OEM if replacing.
