Normally I wear earplugs that take out the higher pitch sounds. Without them I hear a freakish amount of chain noise coming from this engine and primary. Always had it in it's 10k life. All adjustments are good, however I do have .007 runout on the comp shaft which no doubt will cause the chain to vibrate some.
Anyone else find the primary especially noisy in regards to sprocket or chain noise? Bike is 07 Custom

Could be a ghost too ya know............. I've heard that they like to rattle chains.

 

I wear earplugs to tolerate the excessive noise from the primary in my 07 Custom. I had it back to the dealer and after a tech and the service manager rode it they both declared it to be within the normal limits. I assume they have calibrated hearing. Exactly the answer I expected but I wanted a record with them that the noise was there in case something failed later. 20-50 Synthetic was put in at 1000 miles but I went back to Formula + which seemed to help a little. Anyway the earplugs help with the wind noise. There is only about 5000 miles on the bike.

Are the noises musical at all? If so there's an engine that whistles and a tranny that sings. Maybe they could form a Trio?
