I just rechecked my valves yesterday and it really isn't that difficult.
There is enough slack in the wires and hoses under the tank that once you disconnect the fuel pump from electrical and fuel the rear of the tank can be lifted 6 - 8 inches as you pull it back. Prop a piece of board under there and disconnect the evap hose and the electrical connector. I choose to leave the breather hose on the tank and pull it out of the frame.
Set the tank on some boards so the fuel pump doesn't have pressure on it.
Remove the covers to be able to see TDC and turn the engine. Remove the covers to the valves. Remove the spark plug to make it easier to turn the engine.
Rotate the engine clockwise and watch the motion of the valves. When they are both high and you are able to wiggle both you are near TDC on the compression stroke. Rotate it a few times until you are used the movement of the valves.
Then look in the inspection hole and you are probably within an inch of TDC.
I made one of those tools with the square head screw in a piece of hard wood to adjust and hold the adjustment while tightening.
I also cut down a 10 mm box wrench to use on the intake side because it is tight back there with the fuel injector and fuel line from the tank.
Always check the clearance after you secure the adjustment just to make sure you didn't move it.
