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 The previous version was outdated and no longer supported.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

How long do you run a piston in a WR250-300 for enduro, and recreational riding.
I'm not riding it hard and not a lot of WOT, I'm at around 18hours on it it doesn't show any blow by, good compression and no problems what so ever.

Regards, Bart
 
I usually see them needing a piston at about 15-20 hours. Or 1800 miles of our riding. They seems to start to loose compression and power / starting hard by then. Compression is your answer though. If yours is still in spec run it til it is not.
 
I have 84 hrs on 06 WR250 still OK. I don't ride hard, I'm an old guy. Will need to change it soon. I haven't done a compression check but it runs fine and starts 1st kick.
 
You can inspect the piston by removing the pipe and the reeds. I've heard that the intake side will show wear sooner but I ride technical single track so it's rarely on the pipe for long periods and is still like new.(unlike the 125 I had as a kid that was rarely not on the pipe)

I think you have made and error here ! 15-20 hours... the 1800 miles seem ok.
From my experience, 150 hours with a piston is ok for this bulletproofs motor.

Yes that would be averaging 90-120 miles per hour. Maybe 15-20 tanks of fuel.
