98mm Pistal pistons, 13:1, Carrillo rods, +2mm intake valves, headwork by Mike Rich. I have all documentation for purchased parts and dyno sheets. Titanium 1/2 exhaust. To be honest this motor in my 321lb 1000SS frame just scared me. 97.5 hp on the Factory Pro dyno at Café Racer Inc in KC. For reference a tuned 2008 R6 made about 92-93 HP on this dyno. $1500 and you come to get it.
