whine at 70 mph

Postby tlj » Sun Jan 19, 2014 7:32 pm



I just bought a 1993 GL1500 with 51000 miles on it and notice that when the bike gets to around 70 mph there is a high pitched whine that drives me crazy. It gets quieter around 76 but I can still hear it some. Anyone have any ideas? I read in the clymer manual that low oil level will cause a whine or howl in the transmission. Anyone ever have that issue?

When was the last time the timing belts were changed?

Thanks for the quick response. The previous owner kept really good records and the paperwork says they were changed at 46000 miles in Nov 20012.

Kinda off here but mine had a strange noise at the upper speeds too.Sounded like it was coming from the front somewhere.I could hear it on both sides. :?: :?:
The bottom of the ball on the end of the clutch and brake ever had a hole in it. :shock:
Just about a half inch deep,maybe a quarter inch in diameter.
It made the perfect whining noise.Almost a whistling.
I filled them with silicone. :mrgreen:

Might check wheel bearings too just to be safe.

Certainly check out the brake and clutch lever castings for holes under the ball at the end; easy test... put your finger over them if they have holes. Yamaha Ventures had that issue also in the early 80's, a rubber stopper glued in put an end to it (the only gripe I'd ever heard about the Venture, except for its weight). Also try to monitor the noise in a crosswind, if it changes from side to side you probably just have something whistling or vibrating in the wind. Else you'll want to isolate things a bit more and see what makes it vanish. For example get to where the whining is heard and pull the clutch and release the accelerator; allow engine RPM to drop; does the noise vanish. If it does you can focus on wind whistling or wheels and drive train since they are still moving at 70mph. See what RPM you're running at 70 and slow down and drop a gear then return to that RPM the lower gear, again does the sound return, if so focus on the motor. If your careful you might test run for the nosie while on the centerstand - thus no wind. Wind noise is the least to worry about but hard to isolate, unless you recently added something that is exposed to it. Motor, tranny, drive train and wheels are the worrisome areas, hopefully a bit of testing can narrow it down to one area. If all your fluids are up to level and looking to be in good condition then you might be fine, if one is low fill it, if one is burnt or otherwise looking bad then that's where I'd start.
