Up until 07 Vic was able to run the motors on the rich side, and the extra fuel would keep cumbustion temps down a good bit. In 08 the move to closed loop injection, and the leaner A/F ratio that goes with it. Meant they had to drop compression, or run to hot.
Adding a set of cams, and an intake along with the S1 will make the new bikes perform like the pre 08 bikes, and the 106" shines when given the treatment. Still not up to the earlier bikes with an S&S stroker, but 107+/107+ is not unussual with the right pipe
