now im wondering if the turboscoop has made more volume therefor maybe i shuld remove a shim ?
what do you think
Had the same experience with a VZ-R .21. (without modding the head)
The crank pin seem to be a weak spot. It wears much quicker than other brands.
The fact that they perform does not make up for the quick deterioration of certain parts on the motor.
