Oil System
Recommended
–
Silkolene PRO R or PRO 4 15W-50
PRO R/4 is a unique, fully synthetic lubricant for ultimate engine protection
and superior clutch and gearbox operation for high performance 4 stroke
motorcycle engines.
If this specific oil is not available to you, please use a comparable
oil.
NEVER USE CAR ENGINE OIL IN A MOTORCYCLE ENGINE. THE INTEGRAL
GEARBOX WITHIN THE MOTORCYCLE ENGINE WILL SHEAR THE MOLECULES
IN THE OIL. ALSO, MOTORCYCLE ENGINES HAVE INTEGRAL WET CLUTCHES.
Coolant System
50% water and 50% antifreeze/summer coolant.
Fuel
RPE Suzuki engines should be run on a minimum of Super Unleaded 98 RON,
or 100 octane race fuel.
Tuned engines in the USA should be run on racing fuel such as Cam2 or a
minimum of 108 Octane.
Octane Boosters
If fuel of the correct octane level is not available then octane boosters can be
used, please contact RPE before using octane boosters in fuel.

Shell Helix Racing Gear Oil 75W-90
Shell Helix Racing Gear Oil 75W-90 is a synthetic gear oil designed to provide
optimum protection under extreme load conditions, whilst maintaining high
efficiency.
Oil Systems Variations
Due to a number of different oil cooling systems in circulation, the oiling
system must be confirmed before the engine is installed.
Oil System Number 1:
2 blanking plates installed on the engine oil cooler inlet
and outlet ports and the oil jet behind the oil filter is removed.
Oil System Number 2:
-8 or -10 oil cooler fittings on the engine oil cooler inlet
and outlet ports, and the oil jet behind the oil filter has a 3mm hole drilled in
it.
Oil System Number 3:
-8 or -10 oil cooler fittings on the engine oil cooler inlet
and outlet port. A blanking bung is installed behind the oil filter, in place of
the oil jet.
•
On later model engines, that are fitted with a cast type sump pan,
there is only one type of oil system regardless of installation. One
blanking plate on the oil cooler inlet port and the oil jet behind the oil
filter is removed.

If you are unsure as to the specification of your previous engine, RPE
can provide you with the necessary information.
•
An RPE technician can also confirm the specification for you if an
engine exchange is to take place at a race meeting.
