Thanks for all that info Michael that gives me an idea where mine will be. My teacher Dima Elgin made us design a engine around a cam, the megacycle cam I won from a friend in a drinking contest , boy did I pay for that hungover for days. Graph the cam,bore & stroke,comp ratio,carb cfm, exhaust length all came together as one fast SR500 but never was put on a dyno. All from math from that book. But with the Ryca I did none of that , I just got together some parts & built it. As follows a Web cam STD has alittle more lift & duration than stock & hard faced the rockers, ported the head myself and removed all sharp edges in combustion chamber, 10:5 97mm wiesco & Boretech coated , 36vm mikuni with UFO,quad Wingy thingy,dialajet with a heat shield between head & carb,2" header 1 7/8 ID With a muffler I built, repackable, Barnett clutch & springs , Versy's tensioner & plug. So far so good, guess the gearing is higher than I thought, should pull right past 100 mph easy. On One real hard run it barked rear tire & carried front tire for 30 feet on a first to second shift , she's got some big nuts that's for sure,seat & paint and she'll look as sexy as she is fast !
