How do you set valve clearance on Yamaha big bear 350?

To set the valve clearance on a Yamaha Big Bear 350, first, ensure the engine is cold and then remove the valve cover. Rotate the engine to set the piston at top dead center (TDC) on the compression stroke for the cylinder you are adjusting. Use a feeler gauge to measure the clearance between the valve stem and the rocker arm, adjusting the clearance by loosening the lock nut and turning the adjustment screw as needed. Finally, recheck the clearance and reassemble the valve cover.
