It's the clearance between the rocker arm and the valve stem. If it is too large, the valve won't open all the way and you'll get a loud "clattering" noise and if it is too small or non-existent , the valve may not properly close. Either way is a problem. To adjust the valves the engine must be COLD. If it's not cold, the setting will be wrong. Then remove the valve cover. On single cylinder engines there are two valves one exhaust, one inlet.

This may be marked with a "T" on the flywheel see image below At this point both valves should be fully closed and the gap between the rocker arm and valve stem clearance should be at its maximum. Both rocker arms will be at minimum height positions on the camshaft lobes. Check your user manual if you have one. If you can't find any timing marks for TDC you can rotate the engine clockwise the cam lobe is about degrees away from the rocker arm. This means that the clearance between the rocker arm and the valve should be at it's maximum and you should be able to wriggle the rocker arm back and forth a bit that's the clearance.
