The brand-new 2008 Zenoah G270RC engine is a 25.4cc (34mm bore, 28mm stroke) performance machine. Zenoah took their powerful, reliable G260RC engine and made it even better. Major changes include a 4-bolt cylinder design for improved sealing and reduced gasket blowout (an improvement from the 2-bolt cylinder design of the G260RC); a stronger and lighter crankcase; an additional crankshaft bearing; redesigned cylinder fins for better cooling; larger ports; the high-performance WT-813 carburetor with accelerator pump as standard equipment; a metal-impregnated insulator gasket for a better seal; and modified cylinder hardware to better resist vibration. This engine offers serious performance.
