Hey Dyno, Kaama might be moving up to 572's. Can't get enough oomph from the 540's. The 540's would slide right into the Sonic. I might even ride with you then. I think Jason's engine made around 460-465 hp. I think KAAMA said the peak torque was at 3500 rpm but I don't remember what it # was. That was with the existing cam, not the Ultradyne.
