Don't forget grease fittings...most bikes are neglected in the area of steering column bearings/races. Your front end sits on two bearing races where fork assembly meets frame...they usually have grease nipples and need to be greased w/ a grease gun at least each spring. If not greased, the bearings can wear out REAL quick...and are a major pain/expense to replace.
The li'l dinky grease guns are SO much easier to work with than the usual overly large ones, especially when it comes to re-loading grease.
