"What did you do to your bike today?"
Put on some new NGK plug caps on the CB750, fired her up... right winker idiot light didn't come on. Spent the next hour trying to hunt down the problem with a tester light, nope. Had the whole indicator light box opened up... couldn't find a short or the problem (found a spider nest in there though). In aggrevation, I cursed out the bike, put it back together, turned the key... *&!^@ indicator lights work again.
Plug caps weren't enough it seems. She always wants more.
