All machines do not carry oil

This engine has a three disc crank mounted heavy duty manual clutch. The head has a large domed combustion chamber with large valves. The intake valve is 27mm exhaust valve is 23mm.
This engine must be a neutral to start with a kick starter.

This engine does not come equipped with an ignition system (CDI). Additionally, all engines undergo an oil-draining process before leaving our factory. Therefore, without an ignition system and with no oil remaining inside the engine, you will need to add engine oil (4T oil) during the initial setup after purchase.
