Can you post a video of how it sounds?

The VN750 always makes a lot of mechanical noise when running.

the video !!! it souns clearly from right side of the bike
in the left you must ignore the exhaust "leak"
otherwise the bike runs great
i must do a "engine segmentation" hopefuly my google friend hat translated this corectly!!

The video is set to private, so we can not see it. Can you set it to unlisted?

set to unlisted so it can be seen
i have manual tensioners not acct
set manualy till the rpm starts to drop but still the chain noise can be heard while riding...that-s the thing doesnt make any sense ...at list not to me
it feels like something is elongathing the chains wearing them prematurely
thanks mates!!!!

You know, my petcock made that same noise that you're hearing when the spring was failing. The sound was radiating through the tank as if it was an engine sound, but wasn't.
