i just had some weird electrical going on the other day. i rode to work and when i got off i turned the key to off and the bike shut off but the dash stayed on. key out dash was still on..... bike wouldn't turn on when i turned it to on so i unhooked the batt and check all the wiring as i too have the 6.4 tank. couldn't find anything so i hooked the batt back up and now its fine. i think i might have had a loose ground too as when it was still hooked up if i moved the batt around it would flicker the dash.
anyway i might be out in lake george on friday. look for a red hyper
