Valve adjustments are very easy. Grab a manual and have at it. It takes longer to remove the gas tank than to adjust the valves.

There's not a special tool needed. Once the covers are off and the engine is at TDC, a 10mm wrench, flat head screw driver, and feeler gauges are the only tools needed.

What's the needle nose for?

The flathead screw driver is used for the actual adjustment.
