Im not sure where to start. I have a 2003 zx6r 636 gel battery bought last year, pc2 been on since bought bike, original owner, original headlight. I noticed this past weekend that when I started the bike up the headlight didnt come on instantly like normal. After a min or two or when I increased the revs then the light came on. At first I hit the high beam to see if the bulb was burnt out that didnt come on until the low beam did. Any idea where to start looking. TIA!
