head flow data
did some EXCEL spreadsheet on head flow data.
195cc Canfield, 195cc TFS and 191cc AFR intake flow

195cc Canfield, 195cc TFS and 191cc AFR exhaust flow
http://stealthram.com/headflowfiles/...xhaustflow.gif
AFR191cc vs Sportsman II 200cc exhaust flow

AFR 191cc vs Sportsman II 200cc intake flow
http://stealthram.com/headflowfiles/...intakeflow.gif
what you'll notice is that the 200cc heads flow less than the AFR 191cc. ports are huge and velocity has slowed down. so it's not always a good thing to go too big.
