I had my Banshee and Blaster dynoed this past Sunday. I am disappointed in the numbers the Blaster put out. I had KOR do my motor 3 years ago and he told me it would make between 35-38 HP. It made 22 rear wheel horse power. I was one size to rich on the main. I haven't changed anything since the original build except for oversized piston. Maybe this is why it will only do 62 mph with 15/38 sprockets and 20" tires.
