Your experience with the carbureted small-block chevy is relevant. It probably ran with an AFR in the 11.5 to 13.0 range. From there to the 14.7 we run, the exhaust temperature gets 50-100F higher (estimated). Our bikes start out at 14.7, which is roughly peak EGT. I've richened my mixture across the board so have cooled EGT somewhat. It may be that future IIce products have that effect too. We'll have to wait to hear.
