NOTE: The R&D RC1 Recreational Camshaft Grind Specifications have been extensively endurance tested to be the best lobe profile for recreational riding or offshore racing.  The lift and duration are similar to the Yamaha 1800 N.A. cam with a total lift average of .368”. The duration on the RC1 cam is less at .050” lift over the N.A., however, the same 6° degree duration advantage is in the recipe. That puts the RC1 comparable on lift, equal on overall duration and a strong low end vacuum to allow the use of R1, R2, and R3 ECU’s.  R&D has worked hard in the duration curve area of the cam paying careful attention to the duration at .050” and overall added duration.

The R&D recreational camshaft kit is a performance modification regrind that is performed in a normal 2-3 day turnaround to your existing camshaft cores.  R&D also stocks Camshaft kits that can be mail ordered direct with a reasonable additional cam core charge. R&D camshaft specifications have been performance tested against the 1800 naturally aspirated cams, and clearly, there is no comparison in the tune ability area.  R&D suggests that the FZ/FZR, and SHO supercharged engines should benefit greatly from a supercharger or turbocharger specific cam lobe profile and design.  If installing the R1 Cams with R&D Pro Tune Cam Timing Gears, a MoTeC or comparable ECU must be used for tuning as aggressive lobe center changes will reduce engine vacuum to lower than 15 inches and special custom tuning will be required.  R&D RC1 cams are a precision tolerance regrind.  Valve lifter re-shimming will be necessary.  R&D will supply shimming specifications with each cam set that will make valve adjustment easy.  R&D recommends the use of Hot Cams Shim Kits also available from R&D.
