engines with piston oiler jets, these high volume,
high pressure oil pumps also work well in stock Evo
and S&S V-Series engines - they fit 1984-’91 H-D Big
Twins. No thicker than a stock pump, gears with
fewer but larger teeth provide increased oil volume
for both supply and return sides of the pump. Supply
gears are 9% wider than stock and standard S&S oil
pumps; 28% wider than stock return gears ensure
proper crankcase scavenging, reduce drag on the
A 96” 3-5/8” Sidewinder big bore stroker kit is an
“economical route to a larger displacement engine.”
This kit contains nearly everything needed to take a
stock 80” Evo up to 96” displacement and includes
S&S 3-5/8” bore aluminum Sidewinder cylinders and
forged pistons, a 4-5/8” stroke dynamically balanced
S&S flywheel assembly, complete with S&S heavy
duty connecting rods and main shafts, head gaskets,
base gaskets, exhaust gaskets; stock cases will need
to be bored out to 3 5/8”. Black or natural aluminum
finish.

range response. S&S high lift valve springs allow the
installation of cams with up to .585” lift. Compatible
with stock intake manifolds, exhaust systems and
temperature sensors for EFI equipped models.
Available in black, natural or polished aluminum
finishes.
80FLSS 80” Hot Set-Up Kit
For 1984-’92
flywheels and eliminate oil carryover. Polished billet
finish. Increased scavenging capacity results in less
oil in the crankcase and less oil carryover - excess oil
from the pressure control valve is filtered - and longer
pump life. Equipped with a stock length oil pump
drive shaft.
This 3-5/8” big bore kit will increase the
displacement of stock 80” Evolution Big Twin
engines to 88” using the stock 4-1/4” flywheels. The
kit includes S&S 3-5/8” bore cylinders, 3-5/8” bore
flat topped forged pistons with rings and wristpins,
head gaskets, base gaskets, exhaust gaskets and
instructions. The cylinders are shorter than stock, so
shorter pushrods and shorter manifold will be
needed to complete the engine. Stock cases will need
to be bored out to 3 5/8”. Black or natural finish.
Performance Replacement
Cylinder Heads
These performance replacement cylinder heads for
1984-’99 Evo Big Twins are designed to be
compatible with a stock style flat topped piston. This
set has a slightly larger 82 cc combustion chamber,
making them ideal for larger displacement
applications, producing a manageable compression
ratio. These heads are original equipment on S&S V96
and V80 engines. Larger than stock 1.900” intake
and 1.575” exhaust valves provide plenty of air while
maintaining port velocity for good low and mid-
Super G Carburetor Kit
Replaces the stock cylinder heads. This kit contains
everything needed to replace stock heads with the
high flowing S&S Super Stock upgrades and optimize
performance with the S&S 561 camshaft, chromoly
steel adjustable pushrods and a Super E carburetor
kit - complete with manifold and a high flow S&S
teardrop air cleaner. The design of the Super Stock
combustion chamber requires a special separately
available domed piston to yield the optimum 10.2:1
compression ratio and to optimize combustion
chamber turbulence for superior flame travel. Black
or natural finish.
This complete S&S Super G carburetor kit contains
everything needed for a complete installation on
1984-’92 Big Twins with standard tanks. The kit also
includes a manifold for engines with stock length
cylinders; 2-1/16 inch bore.

SELECTED COMPONENTS
89” Stock Bore Stroker Kit
Stock bore stroker kits have always been an
economical way to increase the displacement. This
89” stock bore stroker kit upgrades carbureted 80”
H-D Evo 80 Evo Big Twins to 89” displacement at
approximately 9.25:1 compression. It includes a
dynamically balanced 4-5/8” stroke flywheel
assembly complete with heavy duty connecting rods

and main shafts. Stock bore stroker kits re-use the
stock cylinders, saving cost and the retaining stock
appearance of the engine. Minor hand tool crankcase
and cylinder modifications are required. Depending
on the oversize required for the stock cylinders, this
kit requires separately available special pistons.
Pistons are available for stock or S&S Performance
replacement cylinder heads or for S&S Super Stock
cylinder heads.
