Unlike most of those who posted here, I actually have a Bowman (one of the first ones - they were originally only available to International Four Owners Association members) and have ridden other machines equipped with them.
In my experience there was no drop in oil pressure at any time with the deep pan, but a noticeable drop in oil temperature. I noted as much as a 10 degree difference average between comparably maintained 750's with and without Bowman pans, and a larger difference in heavy traffic and or on very hot summer days.
Contrary to what had been posted before, the Bowman gets in the way of virtually EVERY 4 into 1 exhaust system, since it was designed to be run with the stock 4 pipe system. Please remember that the 4 into 1 was a new idea when the Bowman was released. I often thought that was the reason why they were available for such a short time. That, and the quality of the piece as compared to its price. It made most of the Honda castings look like an industrial experiment.
I doubt that there will be any running problems on the street or highway with oil pickup, etc., with the Bowman. If you properly fill the tank and check the oil fil height - which, after all, you should be doing anyway - just ride the damn bike.
Oh, and as for "wow" factor, how does that equate to something that can't be seen from any convenient viewing angle?
