Error code 1 on vstar tourer 950

Have you checked for any error codes?

To actually get to the diagnosis mode (to read error codes):

1- Turn motorcycle ignition switch to OFF & Run/Stop switch to RUN.
Push odometer reset button in & hold.
Turn ignition switch to Ignition and release odometer reset button. Background lighting will 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.
Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting will 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 [Carburetor])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC in 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.
On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.
"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

The actual error codes will appear (format) as "P0374", for example.

For a 2007, that's not an error code.
Seems as if your disabler is activating.
The key fob for the security system needs a clear signal to the module to disarm the bike. That's why the flashers turn on. If the fob is at the bike, the security module has lost it's memory, the battery needs replacing, or the antenna for the key fob reception is not connected. You also need to squeeze the clutch lever to allow the engine to engage also...new safety feature i think for 07.

Beings the "Check Engine Light" goes off and on, there SHOULD be one or more error codes stored in the system.
Have you tried pulling any error codes?

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.


Once you have any error codes, repost them.

A few examples of what some codes are:

B1004
B1134
P0118
P0605

These do not necessarily, are the codes you'll get, but rather just an example of what the format the codes are displayed as.

Did you pull any error codes?

No?

Don't know how?

Either look up, or repost error codes that you did get.

Had the same problem in Sturgis. Voltage regulator

If it's not digital, it's possible, but you have to carefully disassemble the entire speedometer assembly & odometer to do it. I did the same to my 1981 Suzuki GS850 replacement speedometer that had more miles on it than my bike did.

check engine light comes on when starting then shuts off and then comes back on but when i start ridding it goes off??
