You can check for codes:

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.

9 - Press and release the odometer reset button to continue to the next module.

10 - Turn Ignition switch to OFF.

If it is a bagger, change the spark plug wires, stock wires
Change the plugs to a HD 10R12 (two steps colder) gaped at .038

thanks for  the info , i'll check it out

If that doesn't help I suggest you hookup with Herb and pull and have the injectors checked and cleaned. Those are the exact symptoms.

[Unbalanced]

When you turn the bike on do you hear any gurgling sounds.   A lot of bikes end up with holes in the fuel tank hoses from rubbing and vibrations.   Before you go buying anything check your fuel pressure, check for codes, check for good spark, make sure your spark plugs wires are seated and on are on good and tight also make sure your battery connections are on good and tight and clean.  Also make sure the sparkplugs are in good and tight.

Check the charging system to be sure you didnt have one of those bad regulators that have been out there.

Good luck

got a code po261 , i think  front injecter

[Unbalanced]

It means your front cyclinder injectors reference voltage is open or low. This could be a few things, first I would make sure all the wires are connected properly, Make sure your battery is charged and charging correctly.
Hogasm had this issue with his 04 BB.    Believe he ended up replacing that portion off the harness and all was good again.

some sound advice from Razorback / BVHog.
Open/ low is a loss of connection or broken wire, I would start by pulling the injector plug and pull back the rubber grommet at the back of the plug, you can then see where they are crimped on, have had a couple that were holding by a few wires and would throw that code. Also check where the wires are first tied to the backbone closest to the injector plugs, you may have broken wire strands at the zip tie area.
