This simple yet effective tool for Chinese-built makes installation and removal of the variator or alternator child’s play. Whether for tuning or maintenance, this tool will help make life easy. The locking tool is simply screwed and blocks the starter gear, then the central nuts on the crankshaft can easily be loosened with a spanner (variator or alternator). Suitable for all Chinese-built 50cc 4-stroke engines, whether two -valve (139QMA, 139QMA) or the latest scooter with 4-valve technology. A must-have for Chinese scooter owners!
