noise from headlight please help

well as im ridding i get a whining sound and i think its comming from the headlight because i can reach around and press on it while riding and it gets louder dont know how it could be making this noise and dont know how to make it stop.... anyone have any idea what could be happening??? please help!!!

 

Probably the speedo or speedo cable and when you push on the headlight it pushes on the cable. It's not uncommon for the Yamaha mechanical instruments to start making horrible screaming sounds.

 

thanx for the tip that makes sence!!! i think i will try disconnecting the speedo cable and try i hope that is it because it really sounds terrible and it does stop as i slow down and stop!

thanx again bigfitz i do believe it is the spedo cable i took it off and sprayed some wd40 down the cable a few times ... took it out for a spin and no noise!!! so i guess ill be replaceing it very soon! thanx again CHEERS!

 

Probably just needs to be lubed, not replaced. Use some good quality grease instead of WD40.

 

WD40 is only a penetrant, NOT a lubricant.

I wouldn't use grease either, if you live where it gets cold; use a few drops of motor oil or a good spray lubricant.

The problem could also be in the instrument itself, and the act of removing/replacing the cable "disturbed" it enough to shut it up.

You don't necessarily need to replace the cable unless it's worn; take it off the bike, pull the inner cable out, CLEAN it, flush the sheath out and reassemble with proper lubrication. If you find the inner cable is worn or frayed anywhere, or the sheath is damaged or worn through THEN replace it.

Be sure to lube your new cable if you do end up replacing it.
