About
The Chung Yang GP460 engine is a 45.7cc (42mm bore, 33mm stroke) performance machine. Designed after the high-revving Zenoah RC style motors, it features a 4 transfer port 42mm cylinder, high-performance case pulsed Walbro carburetor (19mm bore, 15mm venturi, independent high and low jets) "hemi"-style combustion chamber, and full-circle crankshaft. The combustion chamber clearances have been improved for better thermal control, resulting in more uniform thermal expansion characteristics and reduced dynamic stress at high operating RPMs! Includes 78mm three-shoe inner clutch assembly preinstalled.
