Latest version of this popular sized, high-performance four-stroke engine.
Features a black rocker cover to suit the appearance in scale models better plus a revised oil breather system. The breather now vents from the crankcase rather than being re-ingested in the inlet, to improve running consistency.
The popular FS56-a now features upgrades that make it even better than before! Blow-by oil exits through the breather nipple on the back plate, for more stable operation.
Black rocker covers gives this engine a more impressive appearance. The F-4040 silencer can be positioned to achieve the ideal fit. Mounts with no-mod ease in the same space as the FS-56a.
