Engine Complete 10“ wheel w/o secondary air system 139QMB/QMA

Engine Complete 10“ wheel w/o secondary air system 139QMB/QMA - complete engine for China-based 4-stroke mopeds with 10-inch wheels (3,5x10 / 3,00x10 / 90/90-10 etc.).The engine comes complete with all necessary drive components, alternator, starter motor etc. The carburetor is NOT included. When installing the engine, please take a close look at the alternator: If the ignition cable plug that comes with the new engine has more or less pins than the original engine, please keep the original rotor and alternator. This is a version with 2 pins. All other components are identical to the stock engine.Note: Always check engine and gearbox oil level after installation. We recommend replacing the rather poor oil used by Chinese manufacturers with higher quality engine oil; keep the original oil for a run-in period of about 50km, then change it. You should also check the valve play. We recommend a valve clearance of 0.08mm.For vehicles WITHOUT SAS (Secondary Air System).
