the problem is the rules by nhra have it in such favor for harley it would be impossible for the harley to loose. The harley has 4 valves per cylinder while the jap bike uses the old KZ head layout that allan johnson is building out of billet, go figure a $7K dollar billet 2 valve motorcycle head. As far as the roller cranks, they both have them, yet due to the layout the harley again has the advantage in friction, 1 needle rod bearing and only two needle main bearings where the inline jap stuff has 5 needle mains and 4 needle rods. I wish the japanese would care enough to build a v-twin under the current pro-stock rules and show harley what they aren't in the engineering world.
