Answer 1

Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty "rotary valve" thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber.

With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do.

You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.

Answer 2

reed valves are in a 2 stroke cylinder head
they are exactly like they sound like in a clarinet.. when the piston rises they are closed due to the position the port is in the cylinder . when the piston is down stroking it creates a vacuum hence the reed valve opens and the piston starts to rise closes the reed valve.. 4 cycle engines have mechanicaly activated valves from a timing chain and a camshaft which controls when the valve opens so the answer is NO NO NO

KNOT!!!!
