So, as we all know this bike is fuel limited. It really can't flow more fuel than what it already does at WOT. Has there been any research done on larger injectors to drop into the fuel rail. I have not had mine down that far; but I'm sure someone here has. Essentially what I'm getting at is if we can more fuel we can take advantage of more wide open exhaust. Of course a PCV would come into play to make it run afterwards.
I've thought about the same thing as well as increasing the fuel pressure. I'm sure there is another injector of the same mfg/series that would fit. Problem is trying to find the data sheet and determine the flow of the injector. My goal was to work around having to add some strange gadget that fools the air temp sensor. If your plan was to get a PCV anyway then you wouldn't need to mess with anything else. The OE fueling system is sized appropriately to the output of the engine.
Try searching on "marelli" and "duty cycle" to see thread(s) that have discussed it before. No recollection of anybody actually changing injectors thus far. Let us know how it goes when you do.
Usually the injector rates step up quite markedly from one to the next, so a minor increase is not normally possible. I looked into this at some length for my Tornado. The easiest way to get fine control over the flow rate is to vary the pressure. The valve is in the tank though, and will be mechanical but I'm sure that a method of varying the spring force could be devised. Any change would require a pressure gauge to be installed temporarily so that adjustments could be monitored. Again, I've set this up on my Tornado. You'll need to monitor your AFR as well to ensure you don't stuff it up royally. An electronically controlled pressure relief valve would be nice, but I don't know of any. Just how much the pump is capable of is another consideration.
