To test the ability of AMSOIL Synthetic Motorcycle Oils

and NGK Spark Plugs to increase motorcycle horsepower

and torque, AMSOIL INC. submitted AMSOIL

20W-50 Synthetic Motorcycle Oil (MCV) and NGK

Iridium IX Spark Plugs to Cycle Solutions Inc., one of the

top motorcycle dyno tuners in the U.S., for a pair of

motorcycle dynamometer tests on late model V-Twin

Harley-Davidson motorcycles.

Segment 1: Baseline Test

In order to establish a baseline, each bike was equipped

with conventional oil and spark plugs and placed on the

chassis dynamometer until operating temperature stabilized.

Next, each bike was operated from idle speed

to wide open throttle (W.O.T.), with horsepower and

torque continuously recorded at the rear wheel.

AMSOIL Synthetic Motorcycle Oils

Formulated with premium synthetic base

stocks and high performance additive

technology that provide superior multifunctional

benefits for the special requirements

of motorcycle applications. These

independent and exclusive AMSOIL formulations

provide second-to-none viscosity protection

for hot-running American and metric motorcycle

engines, transmissions and primary chaincases.

Segment 2

The conventional motor oil was removed and replaced

with AMSOIL 20W-50 Synthetic Motorcycle Oil, and

the dynamometer test was performed again. Test results

NGK Iridium IX Spark Plugs

Provide unsurpassed performance in

auto/light truck and powersports applications.

The iridium alloy electrode is

extremely durable to heat, corrosion

and electrical wear. The fine wire

electrode reduces the energy required to create a

spark while providing increased ignition efficiency and

superior ignitability. The center electrode has an extra

anti-fouling mechanism.
