79 ULTRA 250/260/300 • EXHAUST • COOLING ©2013 Hot Products. All rights reserved. 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.

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. Description Part No. RIVA Ultra 300 Exhaust Race Plate RK18100-ERP 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 Description Part No. R&D 250/260/300 Intercooler Temperature 660-82500 Control Upgrade Kit K AWI G IRLS & B OYS R ACING T EAM AT 2013 H OT P RODUCTS IJSBA M ARK H AHN M EMORIAL H AVASU 300 66 - K AWI G IRLS P ARIS /K ANAMORI /K UME 66X - K AWI B OYS J IM F ERRIN /B EN /Y UJI S HIRAKI ACCESSORIES
