  • The R&D performance ride plate, which is specifically designed for the FX H/O is increased in length over stock and has a steeper rocker section, which will add top speed and eliminate the hunt or bow search noticed in the stock ride plate. Also, smoother and tighter turns can be carved and straight-line stability is significantly increased. The O.E.M. speedometer is relocated to the rear of the plate for higher speed accuracy.

  • The R&D Power Plenum Breather Kits unique design will flow much more air than the O.E.M. filter. O.E.M. filters are notorious for becoming over oil saturated causing sluggish low-end power and a loss of up to 500 RPMs! The R&D replacement breather will never become over oil saturated, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R & D pump shoe sealer kit will seal up the FX H/Os pump shoe and pump inlet to promote reduced cavitation, much better hook-up, and add top speed performance.

  • The R&D Yamaha FX H/O Aquavein Intake Grate has been in the design, development and testing stages for 2 years! The new R&D FX H/O Aquavein will significantly reduce cavitation, increase acceleration, add up to 1 mph on top end performance, and keep the H.O. pump loaded and hooked up! Works great on aftermarket supercharged models as well.

  • The R&D Solas FX H/O 14/20 Dynafly is a great replacement impeller over stock! Increased acceleration and 1 mph plus top speed performance gain!
