Note: All testing performed with 1/3 tank of fuel, trim in
neutral, sea level elevation, air temp 80-degrees F.
RIVA Performance Power Filter Kit is installedto increase
airflow to motor. No internal carburetor modifications are performed.
"Tamper Caps" are removed from high and low speed carburetor adjustment
screws to optimize carb settings.
RIVA Cat Temp Sensor Chip is installedto prevent warning
lights & beepers from activating when catalytic converter is
removed.
RIVA Pump Seal Kit is installed. Location specific molded
inserts are siliconed into the voids of the OE pump inlet shoe
significantly reducing cavitation.
Solas Concord Impeller is installed. After extensive
impeller testing we found the Solas 12/18 Concord to be the best all
around impeller for stock and the RPM Kit for the XLT/XLL 1200's.
Billet impeller nose cone included.
R&D Rideplate is installed. The ride plate
increases the "hull lift" when on plan, resulting in an increase in top
speed. R&D Aquavein Intake Grate is installed. Intake grate
provides increase top speed through better jet pump efficiency in
choppy water conditions. Also, Prop spin and cavitation found with the
stock grate is greatly reduced, resulting in improved acceleration.
Riva Cat Removal D-Plate is insalled in place of
restrictive catalytic converter increasing top-end speed while reducing
under-hood operating temeratures and allwing the use of regular
2-storke oild. A high quality stainless steel replica of the plate that
is standard equipment on export model Yamaha watercraft without
emission contols
