OK there are some miss truths there, the pe wasn't designed for the Daytona, it's simply one of the carbs Daytona recommend. I will be surprised if it doesn't need jetting, as mine did when I upgraded to the pe. It will probably run out of the box, but not to its peak performance. You won't have clearance issues with the frame, but you will have to run a uni filter or plumb new intake to the stock air box if your running that. Whether it's better than a pwk is debateable tbh, I believe Craigs 190 with a polini 28mm pwk had more punch than mine with the pe.
Just to clarify, the pe is a great carb for these, and the easiest to tune from what I have read, but there are cheaper options out there. Craigs currently running a 30mm oko on his for example.. Just don't get sucked in by ppl that will stretch the truth to convince you to buy their product...
