Hi, Hdawg and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Improper valve clearance (too tight)
17. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
18. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
19. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
20. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
21. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
22. Faulty neutral, clutch, kickstand safety switch.
23. Faulty fuel pump.
24. Faulty pump relay or fuse.
25. Faulty ignition system relay.
26. Faulty or corroded run/stop switch.
27. Tilt sensor needs a reset.
28. Security system not disarming alarm needs a reset.
29. Check for engine trouble codes.

Drain the fuel either by siphening or removing the cross over tube at the front of the tank and letting it drain that way or just block off those cross over lines and leave the fule in the tank for removal.
0) remove seat
1) drain fuel
2) undo cross over line (bottom front of gas tank.
3) shut off pet **** and remove fuel line from pet ****.
4)there should only be 2 bolts holding the tank on, one at the top front of the tank and one at the back of the tank.
All in all a pretty easy (but possibloy messy) job.

Turn the Bike on and the Radio off and then follow the buttons on the screen. Most people think you have to do it while it is running and this does not work

Disconnect battery , remove the outer primary case, pull back the lock tab on the starter jackshaft, unbolt the retainer screw, then remove the two starter bolts from the right side, sometimes you need to loosen the oil tank mounts to get at these, slip the starter and coupler out as a unit, replace the coupler and jackshaft the same way they came out when the new starter goes in, install bolts , retighten the jackshaft bolt and bend over the retainer, install and fill primary case, connect battery thats it buddy
