    looks ok,maybe a little too rich? maybe from lugging the bike though,I can definetly tell you it at the least needed rings,you have plenty of blowby,you should notice a nice power increase,250s run real nice with a fresh top end

    motul- good stuff.

    piston top looks great for 112 hours. piston is way way worn out, though. almost looks like it seized once on left ex side. dont look too rich at all. keep a fresher bullet in there and the bore will last longer. bores shots are blurry so i cant see diddly there.

    how's the header pipe look? full of coke?

    Looks good. Maybe a little rich but with than many hours who knows. You should notice a lot more snap / power.

    My 09 WR125 had the piston replaced at about 78 hours and it looked very good. Bore looked new and piston looked virtually new. Regardless the ring was shot and the power increased some.

    I have entered races after slapping a piston in. As long as you checked your ring gap and you cycled it a few times IMHO your good to go. :thumbsup:

    - I have never been a big believer in long slow break in. the dukester will be by to scold me now. :D
