Scooters India Sunny FR 100cc semi complete engine assembly (new old stock) Originally assembled & tested by Scooters India in the early 1990s, the semi-complete engine may need inspection.

The engine uses either a late Starstream or a J-50 crankcase (20050001 does anybody have a late Innocenti parts catalogue with this part number in) with a 100cc cylinder barrel & piston (using a 14mm gudgeon pin instead of the usual 16mm gudgeon pin as used on Italian J-range models) earlier SIL Centos did use a 16mm gudgeon pin with there standard piston.

Other modifications include a modified Starstream crankshaft with 14mm gudgeon pin, 4 speed oil seal plate, adjustable upper chain guide, adjustable from the outside. The Sunny 100cc engine assembly would be the ideal replacement to increase power for a J-50 engine but you would need Cento Sunny Fr engine mounts and spindle to fit into your J-range frame.
