PERFORMANCE
PISTON KITS FOR SPORTSTER - KB (Keith Black)
Evolution is the key word as these Keith Black Performance Piston Kits
were spawned from this successful manufacturer's line of automotive pistons.
Machined in the USA, these lightweight permanent mold cast pistons are
manufactured from Hypereutectic 390 Alloy, contain 16-18% silicon, and
are heat treated to T-6 specifications producing a stronger than stock
piston. This special alloy keeps heat confined to the combustion chamber
and reduces heat transfer to the piston itself. The result is a cooler
running piston that can be fit to the bore tighter. Piston expansion is
reduced by as much as 20% over conventional pistons. These tighter fitting
pistons rock less, support the rings better, are more durable and retain
compression better for maximum power. The key feature to these pistons
is the accumulator groove between the top and second ring. This groove
between the rings tends to average the normal pressure between the first
and second ring, keeping the pressure low enough to prevent lifting of
the top ring while maintaining preload on the second (oil scraping) ring.
Each set of pistons include: wrist pins, spiral locks, engine assembly
lube, and Hastings Moly rings. All wrist pins are .792" O.D. Sold
in pairs. Machined in the U.S.A.

PISTON KITS FOR SPORTSTER - Wisco All
Wiseco pistons are forged from hi-silicon aluminum alloy for superior
strength and dependability.
The unique piston
shape
allows
tight
piston
to wall clearances for quieter operation. This shape combined with
a top quality ring package and computerized machined anti-detonation
grooves
offers you the most technically advanced piston kits available. Wiseco
pistons are available with either Hastings X Style or Wiseco XC Style
piston
rings.
All piston
kits listed are designed to be used with stock stroke flywheels only.
Most Wiseco pistons are machined with valve pockets that are
deeper and larger than stock. These pockets provide adequate valve
clearance for most high lift cams, but as with any high performance
upgrade all
clearances
must be checked.
All 883cc
to 1200cc overbore and 84ci Big Bore kits do not require cylinder head
modification or flywheel rebalancing unless
deemed
necessary by the service technician. The 84ci Big Bore kits require
Big
Bore cylinders and crankcases must be bored to accept the larger
cylinders.

26
Tooth Pulleys
Stock Sportster/Buell transmission pulleys are made of cast iron in 27 and
29 tooth configurations. Replace your stock 27 tooth pulley with our 26 for
an instant 4% increase in torque to the rear wheel. (The
28 tooth pulley has been discontinued.)
In addition to 4% more torque to the rear wheel, our pulleys
are lighter and stronger than stock. Less weight translates to
reduced "flywheel effect" and quicker revs. Weight comparison:
Stock 27 tooth cast iron pulley ... 2.875 lbs
Long life pulley, 26 tooth ... 2.375 lbs
#292-56F - Long Life Pulley, Steel,
26 Tooth ...$142.84 including shipping*
|

Install
one of these pulleys with our XL6 to significantly increase the
performance of your Sportster/Buell and reduce the cruising RPM.

Billet
5-Speed Door
If you are doing any serious performance upgrades to your motor, don't
forget about your transmission. Our 6061-T6 trap door is three times stronger

the mainshaft and countershaft door bearings. Our transmission design expertise
makes our 5-speed door the best trap door available, period.
