    Knocking/Tapping on cylinder 4, cold start

    98 Vmax, 18,000 miles, getting a tapping/knocking like noise on cold starts that goes away once warm. Increases with RPM. Almost sounds like the noise a sticky hydraulic lifter makes in a pushrod motor. Possible I need valve adjustment? As far as I know, it's never been done on this bike.
