ETA 45 - 60 Days

Description: High-Quality Taida Cast-Iron Cylinder 52mm 88cc with Cast Aluminum Piston for 139QMB engines. The cylinder bore is 52mm. Taida 52mm Cylinder Big Bore Kit is suitable for all air-cooled GY6 50cc 4-strokes 50cc engines, and most Chinese imported vehicles 50cc (scooters, quads, and buggies).

It’s also recommended to get a 52mm big valve head (Part# NK100.13) in order to take full advantage of the bigger piston valve notch. However, you can use the original stock cylinder head without any problem.

When used in conjunction with a stock stroke of 41.4mm the engine displacement comes out to 88cc! When used with a 44mm stroker crank, engine displacement = 93.4cc!

NOTE: Please, measure with a caliper 139QMB crankcase bore (opening) for 54.45mm cylinder outer diameter sleeve need a minimum 54.5mm bore clearance or boring and machining are required. If, engine case must be bored, order an engine bore tool (Part# 1400-1001).
