Zenoah K114021141 Two-Stroke Crankcase Gasket for G230PU/G230PUH/G230PUM  [K114021141]

G230 crankcase seal for two-stroke engines

This Zenoah K114021141 crankcase gasket is an aftermarket replacement intended for G230PU, G230PUH, and G230PUM engine units. It forms the sealing plane between crankcase halves to maintain compression and block oil or fuel escape during normal two-stroke operation.

The gasket helps preserve crankcase integrity and supports steady throttle response and tuning. When engines show inconsistent idling or starting troubles after servicing, the crankcase gasket is a likely suspect. The item comes without extra packing and fits the model codes in the product name.

Fitting notes: use a clean bench, remove all traces of the old gasket, check correct orientation and dowel alignment, and tighten the case screws progressively and evenly to avoid case distortion. Replace the gasket if it is flattened, torn, or uneven in thickness.

Tuning note: always inspect this gasket during carburettor or crankshaft work, because damaged seals can alter measured compression and affect needle settings; replacing the gasket is a straightforward way to regain reliable engine behavior.
