Hello again, it's Elena.
This engine was supplied by the Yoshimura Factory Racing Department and was used for 3 rounds during the 2015 MotoAmerica season. It has approximately 1000 miles on it and still runs very strong with zero mechanical issues. On Sunoco RMR fuel, it was last dyno'd at 183hp, so on good fuel it should be closer to 190 with the correct exhaust and electronics. It comes as a complete engine that includes head work, re-degreed cams, and lighter crank. It was meticulously maintained with oil changes after each weekend and has been thoroughly cleaned. Thanks for looking!
