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.
With the engine at TOP DEAD CENTER (TDC) Adjust the exhuast valve to .007 and the intake to .005.

The valve clearances for a 1993 Yamaha 350 Big Bear are typically set to 0.10 mm (0.004 inches) for the intake valves and 0.15 mm (0.006 inches) for the exhaust valves. It's important to check these clearances when the engine is cold and to adjust them as necessary to ensure optimal engine performance. Always refer to the owner's manual for specific maintenance procedures and specifications.
