Hyper S-Stage Bore Up Kit (88cc/H-Cylinder) for 12V Monkey (Regular Gasoline Compatible)

The S-Stage allows for an increase in displacement while retaining the stock cylinder head and crankshaft.
The compression ratio of the conventional standard was 11.5:1, recommending high-octane gasoline, but with the S-Stage eco, the compression ratio has been set to 10.5:1, enabling the use of regular gasoline.
This helps reduce fuel costs.
The Hyper S-Stage includes a carburetor kit, a high-efficiency air filter, a spark plug, and a drive sprocket to change the reduction ratio, all in addition to the S-Stage, to accommodate the increased output.
