I used reed valves, and another kind of valve when I turned expert. Didn't really help, as it would indeed flatten out the powerband, but it also stressed the bearings, rings, cylinder walls, and gaskets LOTS more, with the major porting needed, cut pistons, and higher rpm to get the extra top end, since it seemed to add low/mid range. For an amateur like me, doing my own wrenching, I could race just as well for double the time using stock with port cleaning, jetting and airbox tuned to air conditions.
Sorry, my brain is confusing things. I used reed valves in motocross.
But I had a short stint at roadracing back in the late 60's, the rotary valve was what I meant.
Well I Iam going to get the Service Honda 500AF with a ported head, Boyesen rad valve and Ims 4.0 gallon fuel tank, replaces radiator shroud and FMF Q series spark arrestors. I will have lots of fun and get scared with a lightweight bike at only 213.8 pounds with 65-70 hp and tons of low end and mid range torque. Just have to wait for some tax money to come on in Feb 13th when I see my tax man. My last cr500 was like 235lbs and had 52hp. This bike is only 6 pounds heavier than a 2 stroke 125 WOW!! The 4 gallon tank should keep the front end down since gas is 6 pounds per gallon.
305 for 15 REPS, 470 one rep max BENCH PRESS
