usually reed-valve carbs are for 2 stroke mcycles. dont know how it would work for a 4 stroke, essentially the same, 4 stroke runs on the whore-house principle (suck,squeeze,bang,blow) 2-stroke does the same way, but different,(dont know how to explain), again, i dont know if you could use a reed-valve carb on a 4-stroke or not, (although it might be worth finding out :)  :? )

Im pretty sure there is no such thing as a 4-stroke usin reed-valves there is no reason for them, I dont know why but there is no reason for them, Ive seen reed-valves and know what they look like so thats why I think there is no need for them.

Engine basics - Two-strokes: Fuel-air mixture is drawn into the crankcase by the piston travelling upward on the exhaust/compression stroke...as you can see by this sentence, the crankcase is open directly to the carburetors; in order to prevent the fuel-air mixture from going back out the carbs (when the piston comes back down on the power/intake stroke, pressurizing the crankcase) the reeds close between the crankcase and the carbs, under the pressure from the crankcase and prevent the fuel-air mixture from flowing back out the carbs.

Our bikes are four-stroke and utilize valves in place of the reeds. :)
