Anyone have any idea why my headlights seem to flicker when I first start my R11S? I shipped my bike to Korea to keep from leaving it in storage for two years. The plan was to ride it on post and occasionally outside the the city limits. I started the bike yesterday and noticed my lights seemed quite dim and they flickered when I revved the engine. While riding, they blinked completely off for a second. Any ideas ( battery is lithium about a year and a half old; original all alternator and mostly stock bike).
