Whirl, Whine noise Gen 2 RSV

[wm.butler]

2001 RSV with 13000 miles. Whirl, whine @ all speeds even 20mph. Its not in the rear, but I can hear it louder near the front center of the bike. The noise quits when I pull in the clutch. That confirms a driveline issue. Sounds like a bad bearing, maybe the one at the front of the driveshaft. I thought by adding the Samson pipes I wouldn"t hear it but no luck. I replaced both tires & lubed the rear hub. This sound is driving me crazy. Anybody out there have success fixing this problem? Could it be the u-joint worn?

Have you checked the splines for wear?

 

They don't lubricate them well at the factory and they use IMHO, substandard lube. they should be using a grease that contains at least 60% Molybdenum Disulphide.

 

 

How is the gear lube in the rearend?

I found synthetic oil works wonders to quiet down these motors and gear boxes. Straight cut gears are inherently noisy.

I used wheel bearing grease on the rear hub assembly & spines. 80w-90 gear lube in the rear hub. I did not notice abnormal wear on splines.
