Default Top end noise?
I recently repainted my bike and changed all the fluids out. Bike was running fine before now the rear top end sounds like ****. I have attached a video, anyone have any ideas of what it could be? Only thing I did different was I used redline oil instead of AMS oil that I normally use. Please help

No video, but sure a lot of noisy, ticking, taping, clattering Harleys around here lately.

Too many engines out there to even guess. Hope the paint looks good, probably not related. More info would be helpful.

Bike was quiet, you changed oil brands, bike is noisy.

Maybe change back to the other oil?

Did you have bike stripped down to frame for painting?

Different oil brand can make a much bigger difference than I'd have believed possible if I hadn't heard it myself. Switch back next oil change and see what happens.

ended up being the vacuum line for the petcock. Bought a new petcock that is manual so no need for the vacuum line and the line was tucked away. 😂😂😂😂

Ended up replacing the petcock and the new petcock i put on isn't vacuum. The vacuum line for the original petcock was stuffed up under the tank. That is what was making the noise
