And so it should. In 1998, the Cyclone was propelled by an engine that shared cams and heads with recent-model Sportsters. This year, Buell Thunderstorm heads—the big-valve units that helped pump the White Lightning up to 100 horsepower and that Harley’s P&A division now offers as an accessory—sit atop the new Cyclone’s cylinders; the cams remain the relatively short-duration Sportster-spec units. Combine all of those tuning factors with a 10.0:1 compression ratio, and you get a hot-rod tractor, an engine that starts pulling hard just off idle, hits harder yet in the midrange, then happily and willingly winds out to 6000 rpm and beyond. The Cyclone puts out more peak power than the original Lightning, yet thoroughly crushes that machine in the midrange. And that’s with a stock muffler; almost any aftermarket muffler or Buell’s soon-to-come, second-generation race pipe will boost the midrange yet higher.
