New - the high-performance "Version 2" GP290 engine from Chung Yang. 36mm bore, 28mm stroke - 28.5cc. Now featuring improved cylinder plating and thicker cylinder walls for improved reliability - the engine now has a larger 40mm cylinder skirt and corresponding crankcase opening (the earlier version was 38mm). This engine offers serious performance. It features a 4 transfer port 36mm cylinder, Walbro WT-668 carburetor (15.88mm bore, 12.7mm venturi, independent high and low jets), "hemi"-style combustion chamber, and full-circle 28mm stuffed crankshaft. Stuffed crankshaft reduces crankcase volume and improves engine power. Engine is available in black or chrome finish, and with optional inner clutch. You can also choose to purchase the engine without clutch if you already have these parts and don't need them.
