WHAT CAUSES A CLUNKING OR KNOCK SOUND WHEN STARTING MY HERITAGE UP RUNS AWESOME ONLY THAT NOISE
Are you talking about a starter clunk/knock? What year is the bike and how many miles?
2008 HERITAGE 14,000 MILES RUNS GREAT JUST BOUGHT IT SEEMED ABUSED NOT A HARD CLUNCK MAYBE A KNOCK JUST WHEN STARTING UP AND NOT A LL THE TIME
POSSIBLE STARTER CLUNCK
it's hard to say without hearing it? Is it only when you press the start button? once started it's fine, no noise?
CORRECT POSSIBLLY TIMING? OR LOWER END TROUBLE JUST THOUGHT IF ENGINE TROUBLE OR KNOCK IT WOULD BE ALWAYS THERE CORRECT
yes you'd hear it when the engine is running. Does it only clunk when you press the start button? once started it's fine, no noise?
THAT IS CORRECT ONLY WHEN YOU HIT THE ATRTER BUTTON ONCE RUNNING DOES GREAT RUNS GREAT IDLES GREAT
any mods done to the bike? what size engine? This usually happens on 103 without decompressors.
NOT SURE ITS A 96 INCH
is your bike still under warranty? if so, i'd take it to the dealership to have it inspected. If not, i'd make sure all starter connections are clean and tight.
loose connections cause a voltage drop which would cause the starter not to engage properly, or hesitate, knocking on the ring gear teeth not being strong enough to engage into them, causing a clunking noise.
