I'm running .130's .040's with the needles all the way up.
V-stacks and drags. Got over 7000 on the plugs that are in it and
they still look and run good. Also running a DynaS and a set of 2.5ohm Kaw coils.
The PO claimed the motor was bored and cammed but who knows for sure.
They're all punched out until you open them up.
