1981 GS450L, Getting increased vibration through the motor and frame mostly at 4500 rpm, slightly noticable from between 4000 to 5000. Goes away at any engine speed outside of there. Doesn't seem transmission related, will do it in any gear clutch engaged or not.
Does anyone have any ideas of what to look for? or experienced anything similar?
Valves checked and new shims about 1000 miles ago. I am using the Dynatek Dyna S for the 425 with two washers as spacers on the timing rotor and have the Dynatek coils as well.
