I need some advice.
K5 needs it top end.
I've taken the kips cover off the motor and rev motor , the rod move's out ,but not far enough,
while reving motor i can move the rod even further with a large screwdriver.
Is it from the powervalve , drums amd flap pins worn out and won't allow it to open?
the motor got good compression and runs well, but needs that extra rev power I know its got .
Low and mid range power is excellent
The last time i had it apart i notice PV pins had a fair bit of wear on them .
I was reading one of Eric Gorr books and he wrote , "when the drums valve get worn the center wedge valve won't fully open , and bikes get noticeable slower"
