Honda V-Twin Engines - EASTERN EQUIPMENT, INC

1 Honda V-Twin Engines Welcome to the Next Generation of Honda V-Twin Technology Like the rest of the models in Honda 's extensive lineup of GX general purpose Engines , these newly redesigned Honda V-twins offer the kind of high power, easy usability, and all-around hardworking toughness the world has come to expect from Honda . Their 4-stroke OHV com- bustion ensures reliable, easy starting and smooth, stable power output, not to mention cleaner emissions and reduced noise and vibration. Designed for versatility, including PTO shaft varia- tions and mounting flanges conforming to all SAE standards, their user-friendly high reliability, functionality, and flexibility make them the perfect choice for a vast range of applications.

2 Reliable and Easy To Use Highly Efficient 90 V-Twin Improved Starting and Reliability OHV Format Highly reliable shift-type electric starter The 90 V-Twin OHV format featuring an ensures easy starting even in extreme advanced combustion chamber design cold down to -30 C. and superior intake and exhaust Transistorized magneto ignition equipped efficiency combines with a 12V-20A AC generator provides the ordinarily opposed dependable battery charging capacity elements of good fuel even during idling. economy and high Optional recoil starter available for power output at the GX/GXV610K1 and GX/GXV620K1.
