R&D Kawasaki Big Cam Idle Tuner Kit

The R&D “Big Cam” Engine Idle Tuner kit is a simple bolt on parts kit that works to remove the O.E.M. AIC (Air Idle Control) Stepper Motor from the throttle body, and replace it with a fully adjustable, all billet needle valve assembly. The R&D Kit allows precision “Idle” air volume adjustments to be made and securely locked down when “Higher Lift”, “Larger Duration” Camshaft kits are used/installed, along with tighter LSA (Lobe Separation Angle) packages. As Camshaft Lifts/Durations, and aggressive LSA adjustments are made, Engine Vacuum drops or lowers, and engine idle becomes more difficult or almost impossible to stabilize or control, especially with the OEM “Vacuum Referenced” AIC Motor. The OEM AIC is calibrated to concentrate to a much higher Vacuum, therefore aggressive RPM Hunting and Engine Stalling occurs when big cams are installed. The R&D Big Cam Idle Tuner will work to allow a perfect Engine Speed Idle (RPM) with any Camshaft kit, and with just about any LSA Package all the way up to super aggressive R&D RC4 Kits! Super easy to install in 5 minutes, and very easy to adjust! The R&D Idle Tuner Kit fits on all Kawasaki STX-12F/STX-15F/Ultra LX/Ultra 250X/SXR, all years.

SX-R High Performance “Super Single” Valve Spring/Ti Retainer Kit

R&D has developed an economical solution for upgrading the upper valve train that will work great in the 8500-9000 RPM range. The kit includes our “Super Single” chrome silicone valve spring, precision machined premium grade top spring retainers, and custom designed bottom spring locator. The R&D “Super Single” Valve Spring Kit is a recreational and offshore upgrade favorite which offers great valve control and adds improved strength and reliability. R&D has documented that the seat tension or pressure on the OEM stock springs is a low 32 pounds, and coil bind on the stock springs occurs .050” after full lift on the stock cams. As an industry rule or standard, as RPM or Boost levels are increased to the engine, the valve spring seat pressure should be increased 1-2 pounds per pound of boost. As an industry rule, as RPM'S are increased, the spring pressure at full lift should be increased as well to reduce or eliminate valve float at high rpm frequencies. With the stock springs “short lift travel” shimming is NOT an option. Valve Springs and parts MUST be upgraded.

Also to consider is valve spring travel at full cam lift, and to have enough spring clearance freedom to run high performance camshafts or add additional spring tension pressures without coil bind issues.
R&D “Super Single” springs are a “lightweight design” and manufactured from ultra clean, high tensile materials with multi step surface treatments to improve fatigue strength and reliability. NOTE: R&D also offers additional bottom cup shim kits for proper seat pressures adjustments and valve travel settings!

R&D SX-R Crankcase Ventilation Kit

The R&D Crankcase Ventilation Kit is specifically designed for the SX-R works to add additional crankcase ventilation to substantially lower crankcase pressure and reduce crank room heat. Lowering the crankcase pressure will work to keep oil from “pressure migrating” out of the engine in high performance applications. The R&D crankcase ventilation kit is a must install part when using 14-1 piston kits, or R&D “Big Bore” Kits. The R&D Kit comes with all needed hardware to adapt and install the kit, and installation instructions.

Pt. # 215-15005


SX-R Fuel Pressure Regulator

R&D offers a custom high performance fuel pressure regulator system designed to “bolt on” to the SX-R. The R&D Regulator Kit comes completely assembled with all fuel lines, connectors, and fittings in place and ready to install. The R&D Kit also includes the necessary “Port Plug” to easily block off the stock in tank pressure regulator, and custom “plug on” return line fitting. The R&D regulator bracket will allow the regulator to be installed so fuel pressure tuning access is easily accessible. Base fuel pressure is adjustable from 30 to 75 PSI, and can also be set up as a Rising Rate System (60-75) for supercharger or turbocharger applications. The R&D fuel pressure regulator system is very easy to install, and all hardware can be removed and easily put back to stock at any time. Fuel rail and tank return line fittings are O.E.M. push on “snap lock” fitting connectors which will make the R&D Regulator System easy and hassle free to install.

SX-R Water Box Bypass Kit

The R&D Water Box Bypass Kit adds a nice boost in throttle response and acceleration, as well as promotes stronger midrange pulling power! The R&D kit is a quick and simple to install kit that works to reduce the amount of water that being “Pumped” into the Water Box. The amount of overall water to the box is restricted or reduced while still maintaining plenty of water to keep the water box and exhaust hoses cool. The R&D Kit is without doubt, one of the most noticeable 5 minute bolt-on Power Adders available for the SXR!

SX-R Performance Cooling Kit

The Kawasaki SX-R’s stock engine cooling will quickly become inadequate in High Performance arena where Higher Compression Pistons and Camshaft kits, and aggressively timed ECU Packages are installed and used! The R&D Cooling kit for the SXR is very similar to the popular R&D Ultra 310R kit, where Engine Temperature and Oil Temperatures are addressed, and greatly reduced. The R&D’s “Billet” Multi-Port Extra Cooling Block is designed with additional cooling ports over the OEM cooling block. The Multi-Port Cooling Block directly replaces the OEM cooling block mounted to the pump, and allows for an additional Cooling Line (or additional lines) to be added. The R&D Kit adds an additional line direct to the engine which will reduce engine temperatures. The Kit also redirects water flow through the Oil Cooler to reduce oil temperatures. The Kit also works to reduce the amount of water being “Pumped” into the Water Box. The addition of the R&D Cooling Kit will work to ADD Throttle Response, as well as maintain higher top speed averages by getting rid of engine heat fade.

Pt. # 660-81500


SX-R Five Port Extra Cooling Block

R&D’s 5 Port Extra Cooling Block is designed with three additional cooling ports over the OEM cooling block. The 5 port cooling block directly replaces the OEM cooling block mounted to the pump. The extra ports can be used in any fashion needed. For performance builds or in offshore endurance where long sustained runs will generate high heat build up, we recommend adding one additional cooling line to the engine, oil cooler, and intercooler. CNC machined from billet aluminum, o-ring sealed, and anodized for corrosion protection. Additional ½” through hull fittings and ½” cooling hose are available and sold separately.

R&D Foam Engine Insert

R&D has developed an inexpensive foam engine insert that installs under the engines oil pan and takes up the tight space between the hull and oil pan. The gap between the engine pan and hull on the SX-R is very tight! Some areas are as tight as .250 (1/4 inch)! Small nuts or 6mm bolts that may get dropped or come loose for any reason can get under the engine and get trapped! Very difficult to find or remove! If left un-noticed, a fracture or small hole could get punched to the pan causing oil leakage, as well as hull damage! “Not Fun”! The R&D Foam Engine Insert will keep small hardware or debris from getting to these areas. The R&D Foam Insert is Chemical and Fuel Resistant, and can be cleaned with any degreaser cleaner and Re-Used just like a serviceable air filter! Help to save your engine today!
