Like I stated before, the Dyno was not for the "Harley" dealership. Both dealerships DSC and Donahue Harley were owned by one family. In fact, even though they are in two different buildings, the service on all bikes/wheelers/snowmobiles were performed in the shop on the Harley side up until about 4 years ago. That's why they put the dyno there. Once they sold Donahue Harley (last year) that left the Dyno in the hands of the new owners. Trust me, the DSC guys cryed long and hard about that one. But that's the way it went down. They can still rent time on the dyno, but it's a hassle for sure.
Now, why would a "Harley" dealership need a dyno? Don't sell the "Harley Guy" short here, they're men too. They like to build motors, make power, and spout off about numbers just like the rest of us ... In fact, it's much easier and cheaper to tune a Harley for a 20% gain than any superbike I've seen. Of course it's apples to radishes....pushrod motor, air cooled...yada yada yada....but still fun to tweak them. I got a 21% increase out of my '04 Screaming Eagle Deuce with just an air filter, set of pipes, race tune chip, and a little tune time on the dyno.
Plus, don't forget many shops have dyno shootouts. This one does and it brings 'em in from far and wide. Ten bucks a throw, badda bing...badda boom, a little food on the side and you've got a big party. Every year we're talkin' in the hundreds of bikes that come to play that day.
