powervalve governor adjustment

(1/2) > >>

5004life:
my 87 kx 500 has a bog in the midrange if u shift it a gear high , fresh top end,pro circuit pipe and 13/52 gearing......im thinkin it is the powervalve because at an idle the actuation rod is never all the way in , is there a way to adjust the powervalve governor?

cbxracer30:
Are you sure you have the powervalves installed correctly ? The marks on the the gears aren't alignment marks. Also make sure you have good fuel flow [screen clean on petcock] & not sucking the bowl dry on the carb. CBX

kwakman:
just had a look at my 86(same powervalve design) and the round disc at the end of your p/v rod should have a gap when fully pushed in of 5-6mm.HTH.K.
