12,500 rpm...... on MegaCycle springs....HEY AARON that's a no-no!
And with OEM guides eewwww, another no-no.
I've lost my instructions...anyone know how to set a dyna rev limiter to 12,000
How'd the pistons hold up..anybody know? Did they take a lickin and keep on tickin?
Aaron, I've got spared used OEM valves in good shape if you need them.
