i have lifted the 80 suzuki up a hole ,haven't tested it yet cause the ramps are full with the holidays ,when i used it on the dam the performance was not as good as i expected as i only got a few more k's at 5600 rpm out of it then the 60 yamaha ,went up 25% in power and got less then 10% in performance plus vibration ,hopefully caused by the motor being too low ,gonna find out soon .
