What type of oil does a 2004 Honda 1300 vtx used?

Do not use Honda oil. It's garbage. The best oil for your bike is Amsoil 10w/40 synthetic. You can get it on their website. Because it's a wet clutch, always use synthetic. Another good oil is Royal Purple synthetic oil. 10w/40 as well.

The oil is this type of wet clutch is very critical, if the incorrect type of oil was to be added it could cause clutch problems that occasionally can be corrected by replacing the oil with the correct oil, sometimes the clutch disks are impregnated with the super slippery metallic additives like molybdenum and the only cure is to replace the disks. Do not use just any off the shelf in any wet clutch and certainly not in an 1800 VTX, it can and will cost you money. Use only the Manufacturers recommendation.
