Cycle World magazine, June 11 issue.
They added a Athena big bore kit too.
(plus GYTR Slip on muffler,gearing changed to 13/49, EFI box?)
Anyway, H.P. went from 28 stock to 33
Torque went from 17 to 22
Most likely on a different dyno and different weather then HighFive's, but you get the idea of improvements made by the big bore kit!!
Nonsense, I have not yet began to defile myself
