To adjust the valves on a Yamaha 350, first, remove the valve cover and ensure the engine is at top dead center (TDC) on the compression stroke for the cylinder being adjusted. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem, adjusting it to the specified clearance by loosening the lock nut and turning the adjustment screw. Once the correct clearance is achieved, tighten the lock nut and recheck the clearance to ensure accuracy. Finally, replace the valve cover and ensure all fasteners are securely tightened.
