Buzz Killl?

Sorry, either you misunderstood me or vice versa. This is the original intake cam showing one end, then the other just to illustrate the difference. My plan is to make the skinnier lobes look like the fat ones. I dunno if we are on the same wavelength?

I understand. The profile of the lobes was changed, not just the timing as I had originally thought. Was just speculating if Honda made a change to the cams by regrinding flatter ramps after production had started by modifying existing cams as a cost cutting measure.

Wondering how late into the design/production timeline it was decided. The original engineer's discussion on the Honda Global site is gone. You'd think the designers/engineers would have ground the identical, slightly more radical profiles on all the lobes, not just on 2 cylinders. This just sounded like a cheap way of getting a little harshness without a performance benefit.
