Upgrade Ideas

Question for Fix My Hog Hey, I have a question. I have a stock 2003 HD Road King Classic 100th Anniversary. I would like to put a cam in it to get a little more power on the top end. I do most of my riding out on the interstate. Do you have any ideas?

    I just had work on my '04 Road King. Went with S&S 510 Cam Kit, Feuling Hydraulic Tensioner Kit, Arlen Ness Stage I Big Sucker Air Flow Kit, V&H Tuner and V&H 4" Pipes. She's got all the power I'll ever need and then some.

    Recently acquired 89 Sportster, both front and rear signaling lights had been removed, rear wire cut, how do I replace these safety items

    by all means get a really good set if aftermarket slip ons, straight pipes will never give you the power as if you run a mufflers. Your engine needs back pressure. Call the fuel moto guys. They have all you need and their customer service is awesome.

    Hey I also have an ‘03 road king (fireman edition) the bike runs rough sometimes. When accelerating it kinda stutters like its going to turn off. It has died on me twice. When i started it the second time it reved high for a few seconds and when back to normal. Any ideas on what to check?

    I have a 2003 road King 100 anniversary special,my exhaust are just two straight pipes that are the same diameter,does that mean I have no mufflers
