Where is honda vtx 1800c fuse box - 2003 Honda VTX 1800 Retro Cast

SOURCE: First service on a Honda VTX 1800C:

yes it is included on the warranty, check your manual the first service is indicated in there.

SOURCE: 2002 vtx 1800c wont idle, new plugs, wires ok, no fi

AGREED, had the same problem; hesitation, skipping, popping at low speeds. Ran good w/ new plugs for short time. tried injector cleaner. No FI codes. Dealer couldn't figure it out after $200! I replaced the $26 fuel pressure regulator and she runs Great!!

SOURCE: 2002 vtx 1800c has rough idle and skips like fuel

did you sort this out? getting same issues and by poular result it seems to be the fuel pressure regulator.

SOURCE: I have 2004 honda vtx

i had same with my vtx 1800 i adjusted the idle , if you look to the left of engine between the pots there is a little plastic wheel on the end of a cable which goes to the throttle body, i think it is anti clockwise to increase. try this it worked ok for me however there is a cold start on these and it is operated by coolant temperature check your coolant level and top up if neccessary with the correct coolant as specified (not got info at hand)
