Motorcycle Questions? Ask a Mechanic.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially and if the description of "...high beam light works intermitantly..." also includes the blue HI indicator light, then check the headlight HI/LO switch and/or the violet wire from it.
On the otherhand, if it is only on the headlight itself that is intermittent with the blue indicator light consistently lit, then check the bulb socket, the violet wire leading to it and the black wire connecting it to the ground.
In some instances, it may even be the bulb itself once it has heated up.
