The thing is, when a King skips, it completely destroys the Ringdrive on that/those splines. Now if it keeps skipping, then its only gonna get worse. You need a new ringdrive, otherwise your going to have an early grave.
Then, when you get the new Ringdrive(if you're smart you will) you'll have the joys of bedding it in. I think its something like 100 miles, o something similar.
Also dont jab at the hub when you gap. Push against the pedals, because that way it'll grip on the Ringdrive, rather than trying to and missing. The more pressure applied on the Ringdrive, the more it'll grip. If you jab at it, it wont grip, they'll be no pressure on it, and it'll miss gripping together, throughing you off your bike.
