you're not getting enough fuel. Check that all vacuum hoses are connected properly and that the wiring is ok to both throttle position sensors are connected properly. If that's all ok check the fuel pressure regulator, blockages in fuel lines or dying fuel pump (does it prime when you switch on ignition)?

yea the fuel pump does prime i have removed the fuel rail to see if it had fuel in it fuel got there so the bike was laid down to idk if the tip sensor could make it do this or not so

also somtimes i have to sit there and hold the start button b4 it will start to start up so n other word it will be like... turning over...........turning over...... hit... hit ... hit... hit ... tryn to fire up..... fire up then.... choke it self out rite away

check that you didnt kink the fuel lines under the tank if you lifted it...happened to me once. rails still have fuel because its not completely kinked kind of like half kinking a garden hose. gl

got it to idle nw it like ever time i try to give it gas it boggd out yes this is in neutral the mod on the bike is just a full termignoni exhaust

The fuel needs to be under high pressure in the rail, so it is not enough just to check that there is fuel present.

The ECU either doesn't know you have opened up the throttle (sensor problem - TPS, cam sensor, MAP sensor, crank sensor, air leak) or is unable to supply enough fuel (low fuel pressure, problem with injectors or wiring to injectors)
