When i was redoing the rotating assembly i wanted to change the compression, so i installed 10.25:1 compression pistons with 72cc combustion chambers. i wanted 11:1 but the guy over the phone said that it was too much comp. without buying high octane gas. i can buy 93 octane gas here which im sure most people can. i was just wondering if this guy really knew what he was talking about, because in magazines i have seen where crate motors run 10.8-11.0:1 compression on 92 and 93 octane.
