Okay, so we had some headaches, but the result was worth a few bottles of Excedrin. And as with any motorcycle, there is a standout element; for our chopper, it's the 113-inch S&S engine. This powerplant, which won accolades from Damon's engine builders for its ease of assembly and high-quality components, bowled us over with its massive output. Down low, it's reasonably stout even when barely off the idle jet, with decent throttle response. But tug on the wire, and the thumping mill erupts into the kind of arm-straightening, attention-getting mid-range surge that doesn't do justice to the term lunge. This big-incher gobbles pavement the way a Doberman greets the first meal of the day. And yet the engine seems to tolerate the stop-and-go without any bitching, and the diaphragm-spring clutch is remarkably light at the lever and linear in its takeup.
