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 The previous version was outdated and no longer supported.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

Replacing the piston on 2008 WR250 what's the go on seating the new rings , Getting conflicting info some say do nothing others use a scotch bright pad to very lightly score the bore ? .
 
deglaze bore with green scotch brite pad and WD40, service power valve, wash all with soap and water, dry, oil the needle bearing/wrist pin with two cycle oil, do not oil the piston/rings/cylinder, install jug, no heat cycles, go ride normal after std warm up.
 
i dont do anything re cylinder unless ive junked it then its off for new nikasil!
i thought glazed bores only happen if you thrashed it mercilessly from brand new like no runing in procedure?
anyway install new rings piston torque or tighten everything double check and do a few heat cycles avoid high rpm and lug the motor more that usual, your trying to bed the rings into the bore.
