Scheduled a few hours on the dynamometer yesterday for durability testing and initial tuning...Made a few easy pulls to about 5500 rpm to warm the oil...then got serious with about a dozen full throttle runs in high gear from 2500 to 7500 rpm.... Nothing broke and it sounded very sharp....My hillbilly engineered primary chain drive worked flawlessly...
I still need to work on the tuning ,especially the exhaust....95 HP SAE corrected rear wheel HP is a nice number from a pair of vintage 650 Triumphs at 6000 rpm ...but the power barely went up at 7500 rpm. My single engine racer makes 55 rwhp...I revised the exhaust and will schedule more dyno time...
Crappy video, my Iphone was affected by the exhaust thunder....My rider is in the foreground

Three stooges, me in the middle, my friend and rider in the sunglasses and his friend on the left...
