YAMAHA FX-SHO/FZ/VXR/VXS • FUEL SYSTEM
FX-SHO/FZ/VXR/VXS 725
CC/1000 CC PRO SERIES
FUEL INJECTOR KIT
R&D Pro Series injectors offer increased fuel
delivery over our 525cc injectors. The new Pro
Series injectors are offered in 725cc and
1000cc flow rates. Each set of injectors have been flow rate and voltage
comp tested to insure linear accuracy and are shipped with a precision dead
time (voltage compensation) chart that can be added into your aftermarket
ECU’s software program under battery compensations. R&D Pro Series
injectors offer perfectly clean linear response performance from low idle all
the way through the entire power range. R&D has flow rate tested the O.E.M.
Yamaha FX HO injectors and verified them to flow 396 cc at 43 PSI of fuel
pressure, which rates them to flow 39 pounds of fuel per hour. The R&D Pro
Series Fuel Injectors have been precision flow rate tested to 725cc at 43 PSI
of fuel pressure, and 925cc at 70 PSI of fuel pressure, which rates them to
flow as much as 92 pounds of fuel per hour. R&D fuel Injectors perform
excellent, delivering precise fuel flow at fuel pressure ratings ranging from 40
to 80 PSI. Each R&D injector set is packaged complete with all installation
hardware, necessary harness interface connectors, voltage compensation
chart, and instructions.

HIGH PERFORMANCE
FUEL INJECTOR KIT
When boosting the horsepower on the
FX-SHO/FZR/FZS four stroke fuel injected engine, whether using high com-
pression pistons, cams, or higher ratio supercharger compressor wheels, it
will be necessary to increase the fuel flow delivery. The OEM Yamaha SHO
injectors have been precision flow rate tested to be 80 percent peaked on
stock units at sea level without modifications. R&D offers high performance fuel
injectors with a higher atomization spray pattern that are easily capable of
delivering fuel flow specifications to accommodate up to 400 horsepower!
R&D has flow rate tested the O.E.M. Yamaha SHO injectors and verified them
to flow 396 cc at 43 PSI of fuel pressure, which rates them to flow 30 pounds
of fuel per hour. The R&D High Performance Fuel Injectors have precision
flow rate tested to 525 cc at 43 PSI of fuel pressure, and 625 cc at 70 PSI of
fuel pressure, which rates them to flow as much as 62 pounds of fuel per
hour. R&D High Performance Injectors have been flow rate tested to perform
excellent, delivering precise fuel at fuel pressure ratings ranging from 40 to 80
PSI. Each R&D High Performance Fuel Injector Kit will come packaged with
vital flow test rating information that will be broken down specifically in five
pound increments in fuel pressure to give the fuel flow delivery information
that will help in tuning fuel pressure to match the engines fuel flow needs
based on horsepower gains over stock. R&D offers only the highest quality
fuel injectors, fuel pressure regulators, and fuel management accessories,
for all your engine management needs.

3 BAR MAP
SENSOR KIT
Do you plan on running over
14.7psi of boost? If so, our
3 Bar MAP Sensor Kit is
essential for accurate engine
management with high
boost applications. High
quality 3 Bar MAP Sensor
will measure up to 29.7psi, where the OEM 2 Bar MAP Sensor will only meas-
ure up to 14.7psi. It is critical to provide accurate pressure information to your
aftermarket ECU to ensure proper air/fuel mixture and data logging. RIVA 3
Bar MAP Sensor mounts directly in place of OEM sensor with stainless brack-
et and plugs directly into OEM wiring harness.
