"Tech Tips - Subject: Starter Motor Failure
Make: XVS 1100 (1999-2002 Models)
The starter motor used in 1999-2002 XVS 1100 Models may in some instances become damaged by engine kick-back during starting.
Possible causes of kick-back are:
* intake air leak
* Idle speed too low
* Carburetor synchronization is incorrect
* Carburetor mixture is too lean
* Incorrect starting procedure is used
To reduce engine kick-back during starting:
* Confirm no intake air leaks are presentTo reduce the possibility of starter motor damage during starting, a torque limiting clutch is now incorporated into the starter motor on 2003 models. The original starter motor 5EL-81890-00-00 has been superceded to the new type starter motor 5EL-81890-01-00 that is equipped with the torque limiting clutch (see illustration below)"
Note: The illustrations simply showed the old and new starters with the location of the torque limiter in the front head of the new starter.
