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 ADDRESSED AS SUCH AND UNLESS AN OWNER OF A TWIN CAM 88 BIKE IS AWARE OF THE POTENTIAL FOR DISASTER, THE DEALERS NOR THE HOME OFFICE HAVE NOTIFIED HARLEY OWNERS TO MY KNOWLEDGE. THIS HAS BEEN A KNOWN DIFFICULTY FOR SEVERAL YEARS AND IF YOU ARE FORTUNATE TO HAVE AVOIDED A CRASH AND GOTTEN YOUR BIKE TO A DEALER FOR UPGRADED TENSIONERS IT STILL REMAINS THAT WE OWNERS HAVE BEEN LEFT HANGING WITHOUT INFORMATION UNLESS WE CALL AND THEN ARE SADDLED WITH A HIGH COST TO REPAIR WHAT IS A MANUFACTURERS DEFECT KNOWN TO THE MANUFACTURER. AS FAILURE HAS NOT OCCURED I HAD TO SUBMIT NUMBERS IN REQUIRED FIELDS IN ORDER TO GET THE COMPLAINT STATED. I APPOLOGIZE FOR THE DISPARITY BUT WANT YOU TO BE INFORMED. I INTEND TO CONTACT THE COMPANY AND REQUEST SATISFACTION FOR MYSELF AND OTHER RIDER/OWNERS BEFORE DEATHS OCCUR. SOME MAY HAVE ALREADY BUT BEEN FILED AS UNKOWN CAUSE OR RIDER ERROR OR SOME OTHER FICTION. *TR

Engine And Engine Cooling

2006 ULTRA CLASSIC HAS SMOKED SINCE DAY I BOUGHT IT! HAD ONLY 2 MILES ON IT WHEN I WAS GIVEN THE PDI BY SALESMAN. BIKE IS STILL SMOKING ON STARTUP WHEN COLD. SO FAR HARLEY'S ONLY ANSWER IS TO WRENCH MY ENGINE, WHICH IN ESSENCE MEANS I HAVE PURCHASED A USED BIKE FOR A NEW PRICE! *JB
