gear noise

[wingthing88]

Hi All. I have a little issue with gear noise under load on my 88 with 152k on it. When going down the road at anything over 50mph and accelerate it gets really loud let off the throttle and it goes away. In neutral with the clutch disengaged rev the engine and there is no noise release the clutch an the noise appears and increases with rpm, with the bike on the center stand in gear at idle and using a stethescope there is no noise from the final drive and I can pinpoint the noise to the center of the transmission. I've always maintained this bike very well change the oil about every 3k miles I used to use Golden Spectro but with the last three oil changes have used the Rotella T6. Is there some type of additive or a different oil I should use to quite this down or am I going to have to do a complete tear down and rebuild? As a side note this bike has always been noisy until a few years ago I replaced the final drive that was totally shot and most of the noise went away but it's still noisy enough to be irritating and it seems to be getting worse. I love my bike and don't want to replace it nor do I want to suffer a catastrophic break down like bearing seizing and causing a rear wheel lock up. Give me some ideas guys.

You might want to check the U-joint.

It’s not the ujoint already checked that besides it makes the noise in neutral also.

mine made a noise like that i had it checked they said it was the tires causing it

It’s not the tires. It makes the noise sitting in neutral with the clutch released it doesn’t matter if it’s rolling. It is definitely a hear or bearing noise. Sort of sounds like the old Borg Warner T-10 transmission in granny gear.

Lol didn’t even think anything about it. Always willing to listen to suggestions. Never know if I might miss something.
