By the way I have a 2007 K-9, 117 ci, big radius pipes, crane 4, any feed back will be appreciated. Rock on ya'll !

How noisey? What did you ride before? Maybe just normal for your big motor. I happen to think these newer Evo motors are 100 times quiter than the old Shovelheads!

Why just some of the time? That's what I'd be worrying about.

hey Moe & Ray thanks for the replies. The K-9 has always been a little noisey ever since I purchased it. Ive got about 9300 miles on the old dog and by the way loving every mile. The sometime rattle bothers me too. I even changed the oil and filter to Amsoil and still heard alot of rattling the other night. I called the dealer and they said if it keeps up the rattling to bring it in. About four month ago I had it at the dealer, they removed the tins and checked the rocker arms and rod sleeves, said the all lokked great. Im perplexed.

get a stethescope and try to pinpoint.

might just be a loose vent tube in the tank.

saying its not necessarily inside the motor.

Hey Marv, thanks for the info, have not tried that yet, by the way what is a vent tube in the tank?

 

[MARV]

take off your gas cap and right at the neck theres a mount that a tube is welded to the bottom of it. on my bike the weld broke and the tube would vibrate at a certain rpm only. sounded like the valves were coming out the motor. took a while to figure it out.

Thanks Marv, I'll check it out as soon as the weather breaks. Its been raining everyday for the past four days here in Richmond Va. See ya

How about a plugged tappet screen??

Are you running the stock cam? Running a high lift cam with improper selected valve springs will cause valve slap noise as well.

06 K-9 here. I have what sounds like valve train noise. I put a couple of ounces of good ole STP oil treatment in with my synthetic oil and it actually seems to be quite a bit quieter! I don't know it it will last; but, I think I can tell a real difference for the time being. Remember the ads for STP? Causing the oil to stick to stuff better? Anyway...maybe someone else has also tried this?
