2007 Busa crank, no start

[Smalltime_84]

Hey, I have an 07 Busa that I got in a trade. It has always had starting issues but I would be able to get her started eventually. I took it to Waco powersports and they basically took advantage of the fact that I dont know anything about bikes. Once I would get it started it would idle ok, but if dump the gas it backfires and blows smoke. When driving it would back fore and loose pressure around 45 mph and again around 80mph.

I have cleaned out the tank with rust remover, checked the air box for debris, rebuilt the fuel pump, changed the plugs, an replaced the battery.
Thanks
The previous owner was an idiot and he damaged the exhaust pipe where the header and exhaust connect, so there is a leak in that spot.

I am determined to get this thing running again and I don't want to waste more money at a shop. I am extremely grateful for any help in the right direction

IS the Map sensor connected? Sounds like it could be disconnected

Vacuum leak, tps not adjusted properly, or kinked fuel line?

Pull the injectors and clean them, only costs 80-100, I have had to clean both my 99 and 01, and there systems never had rust or anything so sure yours are dirty if you have cleaned rust out of the tank

I know said you rebuilt the fuel pump. Just clean it?

The loss of power is likely due to fuel pressure dropping off. But you say it’s back firing and smoking as well. That would make me think the injectors are leaking causing fuel to load up.
