Engine Fasteners
The 2013 CRF50F engine uses a single cam timing chain with a simple automatic tensioner. Valve timing is maintained automatically as long as the chain tensioner spring is in good condition and the cam sprocket is properly retained. Flywheel bolt torque is the highest fastener specification on this engine and is the one fastener where under-torquing has the most immediate consequence—a loose flywheel creates ignition timing irregularity that appears as difficult starting and rough idle.
