Feels nice but should it?

Okay, so I've recently noticed that when I roll on the throttle aggressively, I get a pulsing vibration in the tank with about a one second interval+/- that maintains until I roll off and it goes away - roll back on smoothly, no vibration. I feel the vibration in my thighs as I squeeze.

Any suggestions where to start investigating? Thanks!

I have a similar pulsating vibration at the tabk when riding along at a constant 4500 rpm or thereabouts and from reading this forum others have had that too which has been put down to harmonics from the airbox. Seems reasonable to me.
Your situation sounds a little different.
I use Suzuki air filters and still have the stock exhaust. Have you made modifications?

Hey Moe_tunes
No she is bone stock. I took her out for a quick rip down the road to make sure I'm relaying the truth. I felt it vibrate in the same pattern gently as background vibration. Much stronger when I've given it the beans though - but then it stays at the heavy vibration when i maintain the throttle (think kind of like you have just rolled over rumble strips). roll off - back to mild vibration...roll on smoooove...mild vibration.

I just checked the engine mounts. Good. The chain is good, though I am at the upper limit of the travel of 30mm. I did discover a hairline crack in the sidewall of the rear tire. Yay more money to spend!
Maybe I'll just get a new bike! hahaha...haha.......sigh.
