LIGHTENING AND BALANCING -$225.00
APE removes excess weight from your crankshaft and then balances
it to race specs. Lightened crankshafts rev much quicker. The
recontoured counterweights have less drag spinning through the
oil mist resulting in more power to the wheel. (The crankshaft
pictured above has had counterbalance gear removed - optional.)
The crankshafts have the oil holes modified to provide more oil
to the bearing. Then it is computer balanced for continued operation
to 14,000 RPM. Lighten and balance customer supplied crankshaft.
Options include removal of the counterbalancer gear,
and crankshaft stroking. If counterbalance gear is removed, see our special lightweight replacement shaft which allows you to remove the entire heavy counterbalance mechanism from the engine here.

All strokers from APE are race balanced to less than 1/3 gram. APE is the only source for these micro balanced strokers.

APE Crankshaft
Department
APE has been
modifying and race prepping motorcycle crankshafts for over 22
years. The most popular service is lightening and race balancing
cranks for racing and hot rod street bike use. This service consist
of precision machining the crank for weight removal and counterweight
reshaping, computer race balancing for extended high RPM use,
reworking the oil holes on rod journals for increased oil flow
at the bearing, and micro polishing all journals. The balancing
department uses the latest state of the art computerized balancer
that is capable of measuring dynamic out of balance to .01 of
a gram. No other balancing shop can balancer closer than APE.
These APE crankshafts
have won championships in virtually all kinds of racing; road
racing, drag racing, three quarter midgets, dwarf cars, mini
sprints, etc. Every model crank is different and requires a different
style of modification.

The advantage
of a lightened crank... Much quicker throttle response, less
power wasted trying to turn a heavy crank means more power to
the rear wheel. The engine accelerates faster. Harder pull off
the corners. Reshaped counterweights move through the oil mist
with less drag. Lighter cranks have less gyro effect. As all
racers know, heavy wheels and brakes spinning fast act like gyroscopes,
and resist being moved off their axis, such as leaning the bike
over for cornering. Same with the crank. The heavier the spinning
crank, the more it resist being tilted when cornering. Light
cranks not only make more power, but help improve handling.
APE performs
the complete lightening and balancing to the customers crankshaft.
Magnaflux to check for cracks, highly recommended on oil cooled
GSXR1100+s and FZR1000+s . Visit the Crankshaft web page for a complete listing
