cc252 - RACE PORTED CY 35mm Big-Bore Kit for +2mm Stroker Engines
$90.00These big-bore kits have been race ported - intake, exhaust, and transfer ports have been enlarged/reshaped for more fuel/air flow and hence more power. Effective displacement of 28.9cc! Kit includes: CY 35mm cylinder, 35mm piston, piston ring, piston pin, pin washer set, pin bearing, circlips, CMR7H spark plug, and cylinder gasket. The squish on the cylinder has been pre-machined to accept the 2mm stroker crankshaft using only the standard 1 base gasket. Provides HUGE increases in engine power, allowing you to use taller gearing for more top speed! This high-performance product requires 91 octane (using the R+M/2 octane rating method) or higher fuel, and comes without warranty. Fits engines using +2mm stroker crankshaft (engines with 30mm stroke) i.e. CY29RC engine. If used together with a +2mm stroker crankshaft, this item will also fit the Zenoah G23LH / G230RC / G260RC engines, and the Chung Yang CY23RC / CY26RC / CY27RC engines.
