2000 VFR Falls on its face under 4000 rpm

Not new to bikes or the VFR, I had an '86 750 Interceptor about 20 years ago...(aw, crap...I am that old...lol) I came back to my roots and picked up a 2000 VFR. Ran great for a few weeks, but has started to display almost identical symptoms to Witch Doctor's post.

Gonna try the last fix 1st (fuel additive) but wanted to put this out there just in case anyone with a 5th gen has experienced anything similar. Advice? Opinions? Scathing remarks (lol)? Great site, great info. Any insight would be appreciated.
