G'day From Downunder Again
Was just wondering whats the difference between reed valves and the rotary valve. I understand that reeds open from crankcase suction and suck thru fuel and air, and the rotary valve works just like a gate, as it spins around. Is one system better than the other? I thought rotary (800cc) must of been better, but then seadoo went back to reeds for the 951cc. I was told some motor bikes also use a rotary valve. Whats the theory of the difference's between both systems? And which is the better system?
If reeds are better would it be possible to remove the rotary valve and adapt reeds over the ports? Would it run better, the same or worse? You could always remove the rotary valve shaft.
I wouldnt do this, but am just curious to understand why they changed, and which is better.
Thanks Guys
