I got a 2014 Evox gsr and I got a problem annoying the hell outta me everyone I talk to can’t pin point what it is but sometimes (not all the time) when I got my ac blowing a slight knock will slowly start to come when I’m moving I hear absolutely nothing even with ac still on, when my clutch is in not a nothing it’s literally only there when I am stopped with ac on sitting at idle with the clutch out, if I sit there without ac on there’s nothing if I rev with ac on there’s nothing even if there was before I revved it, if anyone has a explanation or can Atleast put their 2 cents in that would be minty🙏🏻🙏🏻🙏🏻

 

Just guessing here.. but maybe the harmonic balancer has an issue. With the AC at load at idle the vibration is just right to be noticeable.
Again, just a guess.
