Harley Davidson Forty Eight’s Starting and Sound

Harley Davidson 48 with mild modifications. Produces great sound with Vance & Hines pipes. Screamin’ eagle breather. Swap Petrol tank with an old one which is slightly bigger. Side mounted number plate. Tried to replace the seat with classic one with springs but didn’t find it as comfortable. Still looking for short rear fender. Please advice if you have any great idea for further changes. Thanks
