Confusing indeed. There are many factors involved with this problem. I find it difficult to stitch everything seamlessly into short, staggered posts. The vibration does get worse with speed. When saying “lessened in 6th gear”. I was referring to the frequency of the vibration. Slower frequency, but worsening vibration. It’s all very confusing to try and explain something I don’t fully understand myself. Sorry if I’m starting to sound like a conspiracy theorist now or something. Super grateful for any and all interest
