R&D ULTRA 300
PERFORMANCE
EXHAUST PLATE
The R&D Performance Exhaust
Plate replaces the restrictive OEM
exhaust honeycomb filter that
Kawasaki recommends inspecting
or replacing every 25 hours. The
R&D Exhaust Plate eliminates
excessive exhaust heat and flow
restriction produced by the OEM
exhaust filter. Improved exhaust
flow decreases back pressure, and heat and increase performance. The
Exhaust Plate also features small water ports that decrease water flow to the
water box, which eliminates hard starting conditions from wet spark plugs.
The R&D Exhaust upgrade never needs to be inspected or replaced. Kit
comes complete with gaskets to install.

EXHAUST RACE
PLATE
RIVA’s Exhaust Race Plate allows
easy removal of restrictive
honeycomb element on Ultra 300 for
competition use. OEM exhaust
element is located inside exhaust
manifold obstructing exhaust flow
and producing excessive heat.
Installation of Race Plate increases horsepower and reduces under-hood
operating temperatures. Plate is precision machined out of high quality
stainless steel. FOR COMPETITION USE ONLY.

ULTRA 250/260/300 INTERCOOLER
TEMPERATURE CONTROL UPGRADE KIT
The R&D Ultra 250 Intercooler Temperature Control system was developed to
offer an inexpensive complete bolt on kit that will allow the full performance
and cooling potential the O.E.M. intercooler has to offer for recreational
applications. Intercooler core water temperatures have a range of affect on
the supercharged air temperatures that enter into the engine. The Kawasaki
Ultra 250 Intercooler operates on a dual line entrance mixture of lake
temperature water and hot (140 degree) engine water that enters from the
exhaust manifold to the top of the intercooler. R&D has found that bypassing
the hot engine cooling water directly outward, and adding an additional
intercooler cooling line, there can be a substantial and noticeable increase in
low end and midrange power along with reduced detonation. The R&D
Intercooler Temperature Control Kit also includes an industry first intercooler
pressure relief blowoff valve to keep internal water pressures down to safe
O.E.M. pressure ranges. R&D offers a range of machined flow control fittings
to allow water volume control tuning for intercooler temperature adjustments
for warm lake water and extreme hot air conditions. R&D offers an additional
pressure relief blowoff valve kit for high water volume flow rates on higher
boost Performer and Stage 1 engine kits. The R&D Kit will allow temperature
tuning that will deliver surprising results.
• More horsepower with cooler intake air temperatures
• Increased acceleration and mid range performance
• Reduces detonation in hot weather conditions
• Temperature control tuneability
• An inexpensive recreational performance addition
• Pressure relief valve preserves O.E.M. intercooler
• Easy installation instructions
