  • 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 The previous version was outdated and no longer supported.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 Cleaning?

Bench Racer 117

I know the PV gets super black from the oil. I read a little about cleaning it here. But what's the best cleaner to use? What's the process? Will I need to take a bunch of stuff off under the cover?
Thanks.
 
I have a 00 WR - I cleaned the powervalve with carburettor cleaner aerosol. I didn't disassemble it - just removed the covers (Front, LH & RH) and cleaned it until it was moving freely when disconnected from the drive ( under the LH cover). I haven't gotten my head around the setting instructions in the user manual yet so maybe I should have done a more thorough job. - (Have changed my premix ratio to 50:1 per instructions from Husky Importer).
 
There's a front? I guess I'll see it when I take the pipe off.
Does cleaning it up really help? Is it going to make a difference in power delivery? Or is cleaning it more of a maintenance job? When I did the top end last year I didn't do any real cleaning while I had it open.
