Question about 2003 Harley Davidson FLSTC Heritage Classic

1 Answer

I have a 2003 HD Heritage EFI (12k miles)... I have noticed when the engine is idling it sounds fine. When I am at highway speed (65MPH & 5th gear) I have noticed a loud intermitent clatter. at low speeds it is not noticable. If I let off the throttle the noise goes away. Any ideas?

Sounds like valve clatter, a common issue. We chased the same noise, with HD installing new push rods, adjustable rods and then they said it is a Harley. Not a real answer. This noise ruines the ride as it grabs your mind and focuses you on the noise.We tried different rod extensions within the lifter adjustment range, same deal. We chased for about 1 1/2 years, trying to not void warranty.

The only long term solution was to go to aftermarket (velvet touch) lifters and lifter blocks. Now we NEVER hear the issue.

my 2003 camry did the same thing when i changed the battery. this is how i fixed the problem. this is very easy to fix, take the car on the freeway or highway and get the speedometer up to 65mph for a few miles then get of the highway shut the car off wait 30 sec, then turn on the motor while in park and rive up the rpm's up to 4000 and then let off the gas it should reset the idle back to normal

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

2003 chevy 1500 hd engine light flashes temporarily when coasting downhill at highway speeds (ie 65mph or faster). When diagnosed, no error codes present.


Does it feel like it is missing when the light is flashing?If not then all you need to do is have a crankshaft variation learn done.This will take care of this problem.Just had a couple of these at the dealership myself and this took care of the problem.If it is missing then check the ignition system like the plugs,wires,and coils.Also check the intake manifold for vacuum leaks.Hope this helps.Good luck.

2007 FLHTCU Transmission Noisy 5th gear


Wow, valves and other related engine noises don't care what gear you are in, they still make the noise. However your motor may be "lugging" in 5th gear which can cause a symptom of an engine related issue.
You may have an issue with the actual gearbox its self.
There is a primary drive chain that may be worn which will cause excessive noise in top gear because it is putting the greatest load on the engine. This is what connects the engine to the transmission. I think there is a tensioner for your model that will allow you to adjust the free play in the primary drive chain. If not I strongly recommend replacement because this will cause major damage if it breaks.
