SOURCE: shocks

The Road King shocks are air adjustable via an air valve located on the right side of the bike just above the rear tire. Your Harley Davidson owner's manual will tell you what the shocks should be pressurized to depending upon the load on your bike (for instance - if you'll be carrying a passenger - the pressure should be a bit higher than it would be if you were riding solo). Don't even attempt to read the pressure unless you have the specialized hand pump that is used to pressurize the shocks. You can purchase this from Harley Davidson or via a third party online. The valve is a typical bicycle / auto air valve - but ... DO NOT attempt to pressurize it with anything but the specialized hand pump. Using anything else will risk over pressurization of your shocks and that's not good. The shocks hold a very small volume of air at relatively low pressure levels - so the hand pump is a must have.

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'!
