YAMAHA FX-SHO & FZ • INTERCOOLER
©2012 Hot Products. All rights reserved.
RIVA FX-SHO/FZR STOCK INTERCOOLER
UPGRADE KIT
The RIVA Intercooler Upgrade Kit delivers a huge performance gain to your
stock intercooler system. The cost efficient upgrade kit features billet
aluminum spacers that increase the end tank capacity and water flow in and
out of the OEM intercooler.
Key Benefits Include:
• Intercooler exit temps average 30-degrees cooler than stock.
• Increased horsepower with cooler, denser air temps.
• No drilling or machining required to OEM intercooler.
• Includes billet "high-flow" pump strainer providing a second dedicated
waterline to intercooler.
• Replaceable sacrificial zinc anode protects cooling system from corrosion.
• IJSBA/ABPBA Stock Class Legal.

RIVA FX-SHO/FZ ENGINE COOLING
UPGRADE KITS
The RIVA Engine Cooling Upgrade Kit delivers dramatically improved cooling
efficiency to engine and oil cooler for increased reliability & performance.
Greatly enhances water flow & pressure by replacing restrictive OEM water
fittings with high-flow billet fittings and superior routing. Allows the addition of
aftermarket ECU's, high-boost compressor wheels and other performance
modifications that can increase heat & detonation. Includes all necessary
water lines, hardware, fittings and detailed installation instructions.
Fits 2009-10 FX-SHO & FZ models.

ENGINE BLOCK
THERMOSTAT KIT
COOLING OPTION
The R&D Block Thermostat Kit
Option was developed to offer a
way to run “Dual Thermostats”
to the engines cooling system
to control and allow warm up and
pre heat cycles to take place.
Engine Block and Head cooling on the Yamaha Engine becomes difficult when
running high compression ratios, higher boost levels, and aggressively
advanced ignition timing. R&D has found that multiple cooling lines need to be
added to the cooling system to provide enough volume to keep temperatures
stable and in check. The problem is the Single OEM thermostat is too restric-
tive and doesn’t allow enough water volume flow to reduce temperatures with
the added cooling lines. R&D has found a way to add an additional thermostat
that allows enough water flow volume to cool the engine and head and retain
the O.E.M. method for engine pre heat or warm up. The R&D Kit installs as a
bolt on kit directly in place of the corrosion anode. Running two thermostats
allows enough water flow to cool the engine properly. The R&D thermostat kit
option will start to open at 120 degrees, and will allow full flow at 140 degrees.
The O.E.M. stock thermostat opens at 118-126 degrees and allows full flow at
140 degrees. Having two thermostats installed that are full open at 140
degrees, and flow enough water volume, will help to keep engine block
temperatures to between an ideal 150-175 degrees. R&D has done extensive
testing with the engineers at MoTeC both on the Dyno and on the water to
determine that 150-160 degrees block temperatures is where the most peak
power is, any hotter and power diminishes. The R&D dual thermostat kit will be
a must have addition where engines are being run in extreme cold water and
weather conditions. There has been many debates over these theories, and
until now there has been no way around extended warm up cycles to bring
engine temps up before high engine loads can be applied. R&D has found a
way to end the debate and give everyone what they are looking for in a
complete cooling system.
