2006 Suzuki Boulevard C50 problem?

When riding it will not get it above 25mph. Cranks up just fine, but struggles to stay running while it idles. While riding feels like its “bogging”, more gas just causes it to die. I thought maybe bad gas, but the tank has been drained and new gas put in. Also have check to make sure the fuel pump is working and check all the fuel lines. Any ideas?

  • First guess would be a dirty air-filter (if it sat over winter maybe mice/rat nest in the air-box).
    Could also be the injectors got fouled by crappy fuel and wont clear.
    Third guess would be fuel mapping went south or poor ignition spark from semi-grounding wires.
