Tightening cylinder heads Checking/adjusting valve operating clearances (Inspection I) (Inspections I, II and III) C000210l • Remove cylinder head cover. e Caution: Trap escaping oil. RS110980 • Check valve clearance with feeler gauge and, if necessary, correct with adjusting nut/lock. Adjust valve clearances with the engine cold (max. 35 ° C/95 ° F): Inlet........................................... 0.15 mm (0.006 in) Exhaust..................................... 0.30 mm (0.012 in) X Tightening torque: Locknut..........................................................
8 Nm TDC • After adjusting, check valve operating clearanc- es again; it should be possible to pull the correct feeler gauge through between the valve stem and the adjusting screw with only slight resist- ance. • Assemble in reverse order. e Caution: Make sure that gasket is correctly seated. Gaskets and sealing faces must be free from oil or grease. C000070 • Select a gear and turn the rear wheel, or set the piston to TDC on the ignition stroke by turning the belt pulley. X Tightening torque: Cylinder head cover ....................................... 8 Nm Top dead centre on ignition stroke:
• The OT (TDC) mark is visible and the inlet and ex- haust valves in the cylinder concerned are closed. • Tighten cylinder head nuts. Tightening procedure after 1 000 km (600 miles) 1. Tighten the cylinder head nuts one after the other in a crosswise pattern 1.1. Slacken off one nut at a time 1.2. Tighten nut to initial torque.................... 20 Nm 1.3. Tighten nut to specified wrench angle...... 180 ° 2. Unfasten/retighten M10 screw .............. 40 Nm 00.26
