    Is it worth trying to make a boost bottle work with a reed valve two smoke, or is the reed valve expected to be effective enough?

    Just wondering because everything i read suggests it maybe pointless. However my old WR200 was a reed valve and was also fitted with a boost bottle as standard.

    thanks in advance

    (p.s. just for those two smoke buffs out there please)

    I'm in the process of building a reed valve setup. If I get decent results, I'll forget about the boost bottle. We'll see how it goes.

    I have been thinking of fabricating a reed cage mod as well.
    They make a good difference in engine performance.
    I am considering using a reed and reed stop out of an old air compressor.

    I attempting to build the whole thing myself. I want to tune it by trying reeds
    of various thicknesses.
    I'll build the housing from from 2 inch wide, 1/8 thick aluminum stock.
    I have to take care of some clutch issues before building the reed valve, but I have acquired the materials.

    Could you post progress pictures?
    I know that other folks here have been intrested in reed valves too.

    sorry this might be a n00b quesiton, but what is a reed valve?

    More or less its just a one way flap valve. It lets air in, and doesnt allow the negative properties of a piston port motor to effect the carburator to double fuel the air.

    What would be even more benificial is to mill the engine for crankcase reed induction and machine a boost port.
