Default Normal?

So I decided to take my bike to a buddys house to chop my exhaust. Got half way there and my bike died. Wouldnt start even with full choke. Put it in the back of the truck and took it to his house. Charged the battery, chopped the exhaust and it ran great. Drove it home then went out with friends. Ran great all night till I was two blocks from my house. Then it died and I got to push it at 2 am. So I checked the fuel pump and it was sparking. Read on here thats bad so I disconnected it and gravity fed it. It starts up great and idles fine but if I snap the throttle then it bogs and dies. If I ease into it then it revs fine. I wanted to know if that is normal with gravity feed? Or am I missing something?

I believe if you swap over to gravity feed then you need to go to the f2 petcock? Can't be positive but I'm pretty sure I read it somewhere on a forum. Hopefully someone can confirm this

Yesterday afternoon I switched over to gravity feed. I put her up to 9k and about 110 mph with absolutely no problems.

I can snap my throttle no problems at all.

Did it sputter before it died? Or did it just stop immediately?

Its fine if I slowly throttle it but if I snap it then it just dies. I noticed that if I turn the idle up to around 3k though then when I snap it it sputters then revs high.

Do you have fairings on your bike? because my accord pump is pretty much all covered by the fairing
