    Hey Guys

    I've got my wr 300 back together after the seizure and it seems to be running great again like last time. Starts first kick, idles great, however something's not quite right in the top quarter of rev range. It almost feels that it's not getting enough fuel up top, and as it seized when ridden in this range last time I'm
    Hesitant to ride it to hard now.

    I've done some research but just wanna be sure before I start fiddling with things to much, the powervalve is situated on the back side of the carb above the inlet, at the rear side of the bike??

    Looking at my carb there's a screw with a spring, is this it? And also which way should it be turned?

    correct.

    Also don't you have the instructions? Read them. They are here. Very simple operation to tune this carb once you read it. Crank that think open (counterclockwise) to about 2 turns out and then work in til it feels right. Simple.
