Jims Damage Control engine failure detection system provides an early warning of catastrophic engine failure by detecting ferrous debris within an engine's oiling system. Using state of the art technology, the special drain plug monitors ferrous particles in the motor oil. When the amount of particles in the oil reaches a level that could indicate impending trouble, the LED warning light illuminates in the handlebar clamp, alerting you to investigate the trouble. This early warning can potentially save you a load in repair costs. The system includes a complete wiring harness, drain plug sensor, and your choice of black anodize or chrome handlebar LED & clamp housing for 1" handlebars. The Jims Damage Control kit installs easily with no cutting or splicing on all 1993 to present Touring and 1991 to present Dyna Glide models. Kits for use on 1 1/4" diameter handlebars are available upon Special Order.
