This is a dyno test of a 790cc Bonneville. This engine has the 360 degree crank for proper vintage Brit bike sounds. Pipes are perforated core baffled Megaphones, intake in handled by twin large K&N pod filters, the air injection system is removed, mains in this run were 150 size, 152 would be perfect, pilots were 42 with the mixture screw out .5-1.0 turns and the needles raised 1mm. The 790cc engine is fantastic, making over 65 bhp on our dyno, for comparison, a Harley Davidson TC88b with pipes and filter makes about 62 bhp, and it is 1420cc
