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

Go to sites like Dennis Kirk and punch in your year, make, & model. Check out exhausts, air intakes, EFI tuners that fit your motorcycle. See if a Stage 1 upgrade gives you the boost you need. If you want to invest more, look at big bore kits from S&S and or a drop in cam. Read the overviews and see what looks best for your style of riding and budget.

      My 02 LowRider (88CI) has Vance and Hines straight staggered long pipes of the same diameter from the ports. There are baffles in the ends but no muffler or catalytic converter. I suspect yours are the same from what you describe. I tried taking the baffles out to see what would happen and it got louder but it also didn’t run correctly at low speeds and was harder to start. I put the baffles back in because the thing is loud enough and runs like a top. Hope this answers your questions at least partially.

    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?

    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.

    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.
