All rights reserved. YAMAHA FX-SHO/FZ/VXR/VXS • ENGINE 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 OEM 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 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 dual spring kit (part # 612-93001) 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 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 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 (Sold in sets of 16.) RIVA YAMAHA 1.8L ENGINE PERFORMANCE VALVE SEALS RIVA’s high quality viton seals are extremely resistant to heat and abrasion. Superior sealing keeps unwanted oil from contaminating combustion chambers and prevents air leakage through valve guides. A precision seal removal & installation tool (RY19040-VST) is available separately. Description Part No. RIVAYamaha 1.8L Engine Performance RY19040-PVS-1 Valve Seals (Sold in sets of 16.)
