Basically last weekend I was tested by the Rangers at Soneyford CA.
Baffle out at 4250RPM 102.5db
Vortip in at 4250RPM 89db
You can get most of the power back if you jet properly. At least that was my experience.

But its quiet, it doesn't kill performance like the stock baffle, and it isn't too bad looking.

Have you checked your accel pump squirt? I've never had the bog, and when I checked my accel pump the duration was about a little less than 1 second. So I chose not the perform the BK mod. The majority of people here seems to go 0.3 seconds. Just a thought.
Remember I ride a WR250F.
With the Vortip, I use the stock needle, my last jetting change was in January riding at 4000ft and 20 degrees F. Jetting was spot on (for my taste) with 42 pilot, 170main and stock needle clip at #5.
For wharm weather I go down to 38 pilot, 165 main and stock needle between #2 and #5, varies depending on where I ride.
I wanted to get FHN-FHP needles but just didn't get around to it. Then crashed that ride and shattered the right wrist. So my winter jetiing and riding experiments will have to wait until next year
