Owner report 10148742 · 2006-01-26 (January 26, 2006)
MOTORCYCLE ELECTRONIC SPEEDOMETER AND TACHOMETER LOST POWER (NEEDLES TO ZERO). FOUND THAT BRAKE LIGHTS, TURN SIGNALS, AND EMERGENCY FLASHER LIGHTS WERE ALSO A NONFUNCTIONAL, LEAVING ME UNABLE TO RENDER ANY OF THE STANDARD WARNINGS OF STOPS, TURNS OR TROUBLE.*AK HD MECHANICS BELIEVE THAT THE FAILURE WAS THE SPEEDOMETER AND SAY THAT THE FAILURE IMPACTS THE LIGHTS AS THE TURN SIGNALS' AUTO SHUTOFF IS INTEGRATED WITH THE SPEEDOMETER. I THINK THAT THIS DESIGN IS FAULTY DO TO THE LACK OF REDUNDENCY OR SEPARATENESS IN THE CIRCUIT WHICH ALLOWS A…

I AM WRITING ABOUT A BRAND NEW DUNLOP D402 MU85B16 SW TIRE I BOUGHT FOR MY 2006 (HARLEY DAVIDSON) FLHTCUI IN PREPARATION FOR A NEARLY 3700 MILE ROAD TRIP. THE TRIP WENT JUST FINE, FOR ABOUT THE FIRST 450 MILES. AT THAT POINT THE TIRE, WHICH HAD LESS THAN 500 MILES TOTAL USE, SELF- DESTRUCTIVE. THE TIRE TREAD SEPARATED FROM THE INNER CORE ( PHOTOGRAPHS CAN BE PROVIDED). THE RUBBER TREAD ?FLAPPING? AGAINST THE WIRING HARNESS UNDER THE REAR FENDER ENTIRELY SEVERED THE WIRING. BY SEVERING THE WIRING HARNESS, OF COURSE, THE TAIL LIGHTS, BRAKE L…

Owner report 10316874 · 2010-03-04 (March 4, 2010)
FAILURE HAS NOT OCCURED ON MY BIKE HOWEVER NUMEROUS REPORTS FROM OTHERS AND DEALER RECOMMENDATION TO HAVE CAM CHAIN TENSIONERS CHECKED BECAUSE AS I WAS TOLD, IT IS NOT A QUESTION OF WHETHER BUT WHEN THEY WILL FAIL. FAILURE RESULTS IN IMMEDIATE LOSS OF POWER WHICH UNDER HIGHWAY CONDITIONS, FOR EXAMPLE WOULD LEAD TO DECELERATION, AS IN PASSING OR MERGING ONTO A FREEWAY. CONSEQUENTLY, PROBABILITY IS HIGH THAT COLLISION WILL OCCUR RESULTING IN DEATH OR SEVERE INJURY TO THE RIDER. THUS IT APPEARS TO BE A SAFETY ISSUE BUT IT IS NOT BEING ADDRESSE…
