Piston ported cylinder

[CedarHillbiker]

Is a reed valve required with a piston ported cylinder...? What else do I need to know before I install one.

no.
the most minimal stuff to do to a new engine is to plane flat the cylinder head and replace all the nuts/bolts/studs

With a reed valve, how essential is it to use a piston with a "window" of holes on the intake side. What are the symptoms if you do not? I think that is why mine has no torque or rpm?

It is absolutely essential

Does a boost bottle perform the same function as a reed valve?

a boost bottle performs no function whatsoever. it's a snake oil product.
