Oldmike, my new streetglide with the V&H 4" monster rounds and dresser duals the 103 sounds like a dragster/race car I've been told . But it hauls ass. The shovel hits a lick with the S&S cams and dyna ignition I just knock it off to seperate errors. The shovel gets alot of attention had a easy rider photograph a hot chic draped across my bike at Daytona.. cool stuff..
