The bike sounds real nice. Not exactly an HD sound, but a good low rumble at low torque, and kind of a slappy loud when you twist the throttle.

The last tank I had checked the mileage on before the Jardine's and DialAJet, I got about 35 miles/gallon. That was just riding solo to and from work. The first tankful after the Jardine's was a trip to Bike Week in Laconia with my wife on the bike. I got about 42 miles/gallon. Next tankful was right around 40 - half highway solo 70-75 mph, half back roads with the wife on the bike.

The Rumblers I found on EBay - paid $132.50. They're brand new with some very minor surface scratches on the underside of the left hand pipe. They're about $230 at Wing Things. Dial-A-Jet was $99.95.
