I own a 2002 harley davidson flht. Last year (2009) I noticed that my fairing started to vibrate excessively when the engine was at 1500 to 2200 rpm. I bought the motorcycle new and previously did not have this problem. The bike vibrated so bad that the fairing bracket broke. I had my mechanic replace the bracket as well as the front motor mount, which did not help the vibration. My mechanic (independent) believes my engine crank shaft has "turned" or in other words is out of tolerance. After researching the...

problem on line, I have discovered numerous other harley davidson owners have the same problem, with motorcycles from 2001 to 2010 with the same problem. My bike has around 30,000 miles on it, and vibrates so bad at the mentioned rpm's that I can't even see through my mirrors, making this a safety issue as well. *Tr
On all harley davidson twin cam 88 ci engines years 2004-2006 there is a problem with the internal cam chain tensioners. The spring loaded tensioners burn out as early as 25000 miles which if not detected may have caused some accidents. Once the tensioner burns through small metal parts break off and may have already caused accidents due to the engine locking up. It has caused countless failures costing owners between 700 to 1000 dollars to fix if they are still alive. Harley has tried to sweep this under the rug. Burned out parts are available. *Tr
Tl*the contact owns a 2000 harley davidson flht. While riding the vehicle at an unknown speed, the contact heard a noise coming from the motor.

I have heard the rear camshaft on the twin cam engine is weak. And that too much power will cause it to break,causing the engine to stop running. Possibly placuing the operator in a traffic safety situation. Upon contacting, I was told this was a problem, but they were not going to recall it. I also noticed for the year 2000 models they have changed the cams and they are now splnined. I feel this is a safety concern for motorcyclist and should be addressed before some one is injured. *Ak
H-d redesigned the tappets in the evo big twin motor. My motor had 3 of the new style tappets and one of the old tappets installed in it. The rollers in the old style tappet disintegrated, causing metal shavings pumped throughout the engine. A piece of metal got into the oil pump ,and caused a loss of oil pressure, which then caused the engine to get noisy. If a piece of metal made its way to the wrong place, then the engine froze up and caused an accident. This problem also happened on my 1989 h-d, flhtc. Vin #...
