Milwaukee Eight, we started ex-
perimenting with a balancer and
eventually we got it to about 75
percent of the previous engine's
vibration, and that made both
groups pretty happy."
Reducing the valve train noise
meant it also freed up a few
decibels in the exhaust, which
was music to the ears of po-
tential H-D owners and still got
Harley under the EPA's noise
meter test limits.
The move to the single cam
heads meant much of the valve
train clatter from the previous
Touring engines has been
reduced, with idle now reduced
to a thumping low 850 rpm. This
deals largely with another prob-
lem—heat. Lower revs mean less
heat, with that heat dissipation
helped by a new exhaust sys-
tem—another area Bozmoski's
brain bashed away at for the
years of Milwaukee Eight devel-
opment.
"We've reduced the heat with
the pipes," Bozmoski starts,
"but it really comes down to the
