i have a 1999 cbr 900rr with a 1997 900rr engine in it. hears the problem when the bike comes to idle the head lights dim real bad allmost to the point where i cant see at night. then if i have to hit the brake then it gets even worse. does anybody know what would cause that. i just put a used sator in itand its chargingabout 12v at an idle and 16v at 5000 rpm. i was wondering if thats normal.
