Includes lightweight, precision-machined titanium valve retainers, racing valve springs, and base washers. Description Part No. RIVA FX-SHO/FZR/FZS Valve Train Upgrade Kit RY19040-VTU R&D HIGH PERFORMANCE DUAL VALVE SPRING KIT R&D has developed an economical solution for upgrading the valve train by offering a series of upgrade parts that will work great with the O.E.M. retainer and valve seals. R&D has documented that the seat tension or pressure on the stock springs is a low 52-55 pounds, and coil bind on the stock springs occurs .050” after full lift on the stock cams. As an industry rule or standard, as 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 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. The R&D spring kit parts were developed and used with stock retainers during the 2009 season and have proven their performance with an APBA/IJSBA Pro Open National Championship. R&D dual springs are a “lightweight design” and manufactured from ultra clean, high tensile material with multi step surface treatments to improve fatigue strength and reliability. NOTE: R&D Spring Kits must use the R&D Bottom Spring Retainer Cups kit Pt. # 612-93006 for proper assembly and seat pressures! Engine Tuning Features • 70-75 pounds at seat, 140-150 pounds at full lift (standard spec.) • Shim friendly, add R&D spring collar base shims to add 2 pounds per .010 shim • Allows the use of higher lift cams (up to +.080) • Linear spring pressure curve allows smooth precision valve control • High performance materials and surface finishes add to reliability Description Part No. R&D High Perf Dual Valve Spring Kit (16 per kit) 612-93001 R&D HIGH PERFORMANCE VALVE SHIM KIT The R&D spring base collar “shims” offer precision valve spring tension shimming to fine tune spring seat pressures based on boost pressures the engine will run at. The R&D shim kits are offered in the thicknesses of .010”, .020”, and .030”. Description Part No. R&D .010” Thick Shim Kit (set of 16) 612-93003 R&D .020” Thick Shim Kit (set of 16) 612-93004 R&D .030” Thick Shim Kit (set of 16) 612-93005 R&D HIGH PERFORMANCE BOTTOM SPRING RETAINER CUPS R&D spring retainer cups will install under the R&D valve spring and support and house the bottom of the spring securely. The R&D Spring Retainer Cups must be used with the R&D spring kits for proper assembly. Use R&D Valve Spring Shim Kits to fine tune valve spring seat pressure. Description Part No. R&D High Perf Bottom Spring Retainer Cups (set of 16) 612-93006 R&D HIGH PERFORMANCE VALVE STEM SEAL KIT R&D offers High Performance Valve Stem Seal Kits manufactured from only the best high quality Viton rubber materials that will resist high valve guide and oil temperatures to maintain a good valve seal in all high rpm, high performance applications.When valve springs are changed out or periodic head service work is being performed, trust R&D Valve Stem Seal Kits at any performance level. Description Part No. R&D High Performance Valve Stem Seal Kit 612-93007 R&D VALVE STEM CONCENTRICITY GAUGE The R&D Valve Stem Concentricity Gauge is a testing tool to check the roundness and trueness of valves. Small valves can distort or bend from heat produced in high performance supercharged or turbo charged engines. To achieve a perfect seal on the seat the valve needs to be concentric and true in every dimension. Gauge is fully adjustable to accommodate a variety of valve sizes and features a rigid, positive stop that can be set once and the trueness for an entire set of valves can be measured. Kit comes complete with dial indicator accurate to .001”. This is a must have tool for any engine builder to get the most out of your high performance 4 stroke engine. Description Part No. R&D Valve Stem Concentricity Gauge 612-80010 RIVA VALVE COMPRESSION TOOL Riva’s overhead Valve Compression Tool allows easy removal of valve springs and keepers without removing cylinder head. Includes compression adapter to pressurize cylinder keeping valves in place during removal of stock springs and keepers. Fits both Yamaha 1.8L & Kawasaki 1.5L 4-stroke engines. Description Part No. RIVA Valve Compression Tool RY19040-VCT Fits Yamaha 1.8L & Kawasaki 1.5L 4-stroke FZR VALVE SPRING COMPRESSION TOOL KIT The R&D Valve Spring Compression Tool Kit allows easy removal of the intake or exhaust valve springs and keepers without removing the cylinder head. R&D recommends using the compression adapter from a compression gauge kit to pressurize cylinder keeping valves in place during removal of springs and keepers.
