At 1,000 miles I switched to synthetic 75-140 and it did quiet it down some. Just this week I did my 5,000 mile service and even though Harley says the transmission will go 20,000 miles I changed it out again. I feel this has kept the "clunk" you hear quieter.
Once you get used to the quirks and noises of the Harley, I think you will find it quit a reliable machine. I can't stress routine maintenance enough. Use high quality fluids. And you will find several people with very high mileage on their original motors.
Enjoy your Sportster, I miss mine and wish I'd never traded it in. You will find several people on this forum that feel the same.
FYI - Not a fan of synthetics in a HD primary ... too slippery

Okie,

Yes, its normal, yes it means business, yes its an irritation!
Like the clutch pack.
Or
Like the motor sounding like a sewing machine on the highway, but, remember that a sewing machine is a well oiled instrument meant to work long and hard without interruptions and you will get the idea about your HD.

(everyone, cross your fingers and pray for this gentleman and his new toy!)

May the Gods of Detroit or Pennsylvania keep you safe, clean, unbeaten and fast.

Search this forum and I suspect you will find arguments for and against. Issue with synthetics and a wet clutch are the friction modifiers.

Mobil 1 V-twin does not have friction modifiers.

My 02 Sportster shifts very quietly compared to my Russian 05 Ural Tourist. Only quiet shifting Sporty I have had was my 1960 Xl I owned back in 1985-86. It shifted on the "Correct side" too.
