When I asked my machinist how he was gonna do it, he
said "the way I do 'em all." As this was the longest
sentence he ever spoke to me and he was very talented,
I didn't push it (most of his sentences were "Yup.
Nope. Maybe. $125."). I know that you want the 2
pistons going up to exactly counteract the 2 pistons
going down. You can't really do this in a 4 banger,
but you can get close, and it helps smoothness. I
believe Vizard says it will not realistically improve
performance or rev capability. I had the engine
balanced from crank pulley (harmonic balancer) to the
clutch/flywheel. I could not see where he did
anything to the rods, but I'm happy with the overall
results regardless. Make sure the crank is
dynamically balanced (done on a rotating machine), not
just statically.
