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 restrictive 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 tem- peratures 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 temperature 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 Description Part No. SHO/FZR/FZS/VXR/VXS, SVHO-FX/FZ 660-18004 B. A. YAMAHA 1.8 ENGINE COOLING KIT WORX Racing cooling kit allows the addition of an extra water line from the Jet unit which feeds directly into the Yamaha 1.8 engine block to significantly lower engine temperatures under load to increase engine reliability and performance. • Kit includes all necessary Fittings, hoses and clamps you need. • 1/2 hose and fittings.
