New transmissions seem to be noisier than one with some miles on it.

Running 75w-140 gear oil in transmission will help.

What Kainam said.
Noise is in the ear of the beholder too.
Is this your first Harley?

First, make sure the clutch is adjusted properly and that the primary and transmission is not overfilled with oil. Clutch adjustment problems seem to be the main cause of the "clunk"

Most of the "clunk" is caused by clutch drag...... ATF in primary helps.... a bunch. :thumbsup :)

I have a 10 Road King Classic and I hear the gears when they change, and it is louder than my 05 deuce was, also it has a different tranny a 6 speed and not a 5 speed. Can't compare a 02 with a 14.

OH! my noisy transmission

Thanks for the replies.

Has anyone else tried automatic transmission fluid in the primary drive. True you cannot compare a 2014 6 speed box with a 5 speed 2002 box I just thought that the transmission
would be smoother on a newer model. The bikes dew a service any time now and if the dealer cannot sort It will try myself.
The other question I have ,what silencers can I put on the bike to make it sound more like
a Harley and less like a weedy jap bike without messing with the engine and not spending
a fortune .because Harley parts in GB cost a packet of money.

Your welcome Mysterious Bob, I guess riding mine for 6 years and putting 15k on it, I'm used to the loud gear change and it doesn't bother me, was just out today and it's loud.

Should work great. I'd just suggest waiting for the warranty to expire before using a non-specified lube in the thing. I use Amsoil brand and love the feel. Used Pennzoil before that. Any Dexron rated transmission fluid will work just fine. Ford type works, but shifts are rather abrupt, clutch locks up Too quick! Good for racing.

I've owned numerous bikes over 40 years of riding and my Sportster (first Harley) is by far the loudest shifting bike I've ever owned. I have 3,200 miles on it and there has been no change since new. Since I've had no shifting issues I attributed it to being the norm for Harleys.

All of the Harleys I have ever ridden make the clunk when shifting. Some more, some less. Currently 79,000 miles on this one and still clunking.

I did a little racing and discovered that speed shifting and not using the clutch eliminates the noise.

Not a scientific answer, just my experience. I used to think it was the transmission but I am leaning towards the clutch.

Anybody have a Barnett or other after market transmission with other results?

Your engine is actually a big air pump. You can put slip on mufflers on if you don't change the air intake. If you change air intake, you will need to re tune.
