BLOCKOFF FITTING
R&D offers a Fuel Pump Pressure Regulator Blockoff Fitting Kit which will
allow the O.E.M. stock in tank fuel pressure regulator to be removed
completely and replaced with a billet part which is necessary when installing
an aftermarket externally adjustable fuel pressure regulator. The R&D fitting is
manufactured to “Deadhead” or block the port solid, however, the fitting is
pre-machined and tapped and can be relief drilled to be able to install a
Mikuni Super BN Series jet directly into the fitting for a small in tank restrictor
jet which for fine tuning fuel pressures.

DEEP FUEL PICKUP
The R&D Deep Fuel Pickup is designed
to maximize fuel volume. The stock fuel
pickup is located horizontally in the gas tank three inches above the bottom of
the tank. This leaves approximately 5 gallons of unusable fuel in the bottom of
the tank. The R&D Deep Fuel Pickup relocates the stock fuel pickup to the
bottom of the tank in a vertical position. The new positioning allows for 24
percent more riding time per tank of gas.

HIGH FLOW FUEL
INJECTOR KIT
When boosting the horsepower on a
Kawasaki four stroke fuel injected
engine, whether using high
compression pistons, cams, or higher ratio supercharger compressor wheels,
it will be necessary to increase the fuel flow delivery. The O.E.M. Kawasaki
injectors have been precision flow rate tested to be 90 to 95 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 375-400 horsepower!
R&D has flow rate tested the O.E.M. Ultra 250X injectors and verified them to
flow 375cc at 40 PSI of fuel pressure, which rates them to flow 38 pounds of
fuel per hour. The R&D High Performance Fuel Injectors have been precision
flow rate tested to 625cc at 70 PSI of fuel pressure, which rates them to flow
62 pounds of fuel per hour. R&D High Performance Injectors have been flow
rate tested to perform excellent, delivering precise fuel flow at fuel pressure
ratings ranging from 40 to 80 PSI. R&D offers only the highest quality fuel
injectors, fuel pressure regulators, and fuel management accessories for all
your fuel management needs.
