[QUOTE="fastwes, post: 699782, member: 20758"] You may not like my reply, it's not very scientific. I don't worry about crankcase volume! I've tried filling different parts of the cases and never saw any changes in dyno readings. It was downright disapointing! But most engines do respond to rounded or shaped edges like Eric said. Crankcase to transfer flow restrictions or variations make more differences. Obviously bike manufacturers get the whole different systems to work together, pipes, ignition,scavenging,compression(s) etc., even though they may be quite different from the other guys.
