Got this 90 yz 250 a few months ago, nice shape for a 90, anyway... just had the cyl. bored + honed and the head repaired, new top end, bottoms still tight... My powervalve (both halves) seem to hang up and not operate freely (It's the rotary type PowerValve that Yamahe used for years, some of you guys probably can picture it... and when I put the jug on and went to hook up the actuator assembly, the tension from that little spring doesnt seem to be enough to move the powervalve...
Both powervalve halves appear to have been ground by someone who didnt know **** about ****, do i need a whole new powervalve or maybe get these machined a little to move freely?? \
Any input is greatly appreciated, THANKS! -alex
