SOURCE: oil change on 05 road king

I typed out a Real Long dissertation of how to do this step by step, and all of my tricks. Forgot what the primary oil amount is to refill, don't have access to my manuals. (Gloomy day for an old biker)

Went to find this info, and there's an old Harley mechanic, (Kinda' looks like me!), that has a step by step Video of how to do an oil change on a Road King!

Here it is,

SOURCE: what are the pros and cons of synthetic oil in

Using synthetic is all "pros" in my opinion. I've done a lot of research on line and talking to motorcycle mechanics, local riders, local landscapers who all use synthetics. There is a ton of scientific data and wear comparison data out their- so much that, for me, it's a no brainer to use synthetic. After hours of research I decided to use nothing but Amsoil. Make sure you specify the Motor Cycle oil as it is specifically formulated for bikes. You can usually find it locally. Harley has theirs made for them by one of the major oil refineries- they just put their name on it and mark it up tremendously. Amsoil's specs are the best I've found. I have a 2007 Dyna Super Glide with Vance Hines pipes and a 96 Harley Low Rider with a Crane cam, tricked out chrome and 2 piece 3 spoke "saber" wheels- a real beauty!

Hope this helps and good ridin'!

SOURCE: oil weight for primary and transmission on 2003 Road King

You could get away with it for awhile, but I would only use oil formulated for the primary chain case, and for that part of the machine, I stick with Harley brand, dont forget , u got clutch plates in there u dont want slipping. For the tranny you wanna use a good grade gear oil (75W-90, 75W-110,75W-140, SAE 190 & SAE 250) .... it'll better handle the torque requirements. I use Redline Gear Oil and shifting has improved noticeably

SOURCE: where is the oil dipstick on an 03 road king

The oil dipstick is located on the right side of bike almost directly under the football cover for the air cleaner. It's a round knob that pulls directly out (Kind of wiggle as you pull on it). Just check like a regular car dipstick pull, wipe and reinsert and then look at dipstick.
