1. Remove the valve cover so you can see the valves.
2. Rotate the main crank pulley on the right side of the engine until it lines up with the TDC indicator.
3. You should be at the compression stroke of either piston 1 (right one) or piston 2. The intake and exhaust valves are completely closed on compression.
4. Once you determine which piston is on compression adjust that pair of valves and then rotate the engine another cycle to adjust the other piston's valves.
5. Intake valve lash should be .006 and exhaust should be .008

If you don't already have it, download the Kinroad manual for the 650. It has better information on the engine:
