How do you adjust the valves on a BMW r1100rt motorcycle?

To adjust the valves on a BMW R1100RT, first, ensure the engine is cold. Remove the valve cover, then rotate the engine to the TDC (top dead center) position for the cylinder you are adjusting. Use a feeler gauge to check the gap between the rocker arm and the valve stem; the correct clearance is typically 0.15 mm for intake and 0.30 mm for exhaust. If adjustments are needed, use a 10mm wrench to loosen the lock nut and turn the adjustment screw until the proper gap is achieved, then re-tighten the lock nut and recheck the clearance.
