I have a 2007, low miles Harley-Davidson Sportster 883L that is just sitting under a cover with a smart-charger so the battery keeps OK. I took the stock pipes and air cleaner off and put some Vance & Hines Short Shots pipes with a Screamin Eagle air cleaner and a V&H Fuelpak. This baby just sits since I got my 2010 Harley FXD Superglide and it is 1584cc of pure beast, especially since I also changed out the stock pipes to more Vance & Hines, this time I got the Straight Shots. I also had a super tuner and a Screamin Eagle Heavy Air set up along with the Dyno tuning and it is my favorite to ride. I have not been riding it much lately because my 6 year old is out from school and I don't wan't to trust that he will hold on to me while driving.
And yes you really have to be careful driving around town and the major streets actually %100 of the time, as I have had two close calls with women on their cell phones oblivious to anything but their conversation. Most surely you better be careful and that goes for myself also. Enjoy.
