Harley Davidson Twin Cam 103 Ticking Sound

Question 2012 FLTRU Harley Davidson Twin Cam 103 ticking sound starts on cold start up (21,000 miles). It seems to go away after engine is warm. Bike still under warranty and dealer is suggesting carbon build up in head, wants to tear down engine. Not comfortable with that procedure. Bike runs great. Anything else that can be done, such as RingFree or Sea Foam? Have you heard of this problem, with the 103 engines? Thank You, G

Answer G, the ticking you hear @ cold start is more likely being caused by a weak hydraulic lifter. A lifter may be bleeding down when the m/c is not running. The sound goes away when the motor rebuilds oil pressure in the lifter. If there was carbon build up on your valves, the ticking usually lingers even after the m/c is @ running temp.

    I’ve got the same bike and the same problem. Is a weak lifter something that can harm the motor? Should it be replaced ? Multiple dealers have told me nothing about lifters they just say it’s the “nature of the beast”. They also suggest I go back to conventional oil. Right now I use Amsoil

      Hi, Dave. What have you done to determine that you have a weak lifter? Without more info we cannot really speculate. Does your bike need a tuner?
      Was this noise always there, or did it just come about? Are you running 93 octane? Does the sound go away as you raise the rpms? Or Get louder?
      Some Harleys do have more valve noise than others.

        I always use 93, however sometimes I have to add octane boost; however the tick goes away at regular riding RPMS at idle it may or may not return.

        Bike had 900 miles it always had a loud noise ticking drives me nuts. Dealer said cant fix it charge you 100 buck pluse your warranty not right. Go buy something that cost you 20 grand I feel they should had taken care of this problem. Been pissed not going to buy loud pips to cover up this noise. Not happy about this.

      I have a 2015 Road glide with the “103” and I began noticing an occasional ticking, but got really bad after an “1000 mi” scheduled service. The “loud” ticking got really bad a loud at speed, even at idle. I even noticed a reduction of power after the service. I took the bike in and they found that the engine lost some compression in one of the cylinders, was burning a bit of oil, which also found oil accumulation in the the throttle body, oil seems to being bypassing seals… but I am assured the service dept will fix the problem..

    I have a 2012 FLD switchback 103, 5,000 miles, When I bought it used, the owner said it had 255 cams installed at the dealer, it had a mild ticking noise @ 2100-2300 RPM, “which I knew the 103’s have lifter noise” now it has 6,800 miles and I just noticed the lifters are now making a noise at 3800-4100 RPM.
    The guy riding behind me said it smells like its burning rich, “kinda burned his eyes”
    It has a SE tuner , should I just take it back to the dealer and see if the tuning needs tweaking ?
    I really hope its not a faulty lifter.. I dont drive it to easy either, how can you have a 103 with cams and drive it gentle.

      The high output 103 t.c. has the 255 cams, I believe that’s the only difference in the engines. My ’14 Road King has a stage one with S.E. race tuner. It now has 47k on it’s odometer, averages about 42mpg.,runs very strong(slightly faster than a stock M8).I run Redline synthetic & have had no issues or odd noises whatsoever. I love this bike.

      Hi Tom. Some Harley’s make more valve noise than others. Some breath heavier. Some vibrate more. Even when they are the same year and model, there will often be variances.
      It can become expensive to pursue the issue you describe.
      You can try replacing the lifters but you may simply be hearing a valve(s) slamming shut.

    Replaced the lifters which one was bad, with new S&S lifters. No more knocking on start up but still a loud ticking for 30-60 seconds. Starting to sound like the compensator plates making the noise until they get oiled up. ?

    I am in southern Nevada the noise starts when it is hot and the bike is hot Noise varies with throttle
    dealer shop tells me that it is the nature of the machine Should I be worried? Should I insist on them checking something? Is there something I can do myself?

    have a 2013 flhtk stock motor under start up has a tick after 5 seconds it goes away. the tick comes back at 1950-2050 rpm and is more of a rattle, but then goes away when not in that rpm range. replaced lifters and the problem still persists. It seems to be rear cylinder, the bike has 18,000 miles.

    My son just bought a 2013 Soft Tail Slim. Noticed that the valves click. Seems to do it a little more after engine is warm. Runs Good. Oil full. Got about 10,000 mile on motorcycle.Does the valves need adjusting maybe?

        My son’s 2013 Soft Tail Slim 103 got very much louder with the valve noise. My buddies and I pulled the rocker box covers and could not find anything wrong. We also pulled the push rods and they looked OK. and it didn’t fix. Now we ate replacing the hydraulic lifters with new one’s and using adjustable S & S push rods. My question is, do you have to pump up the lifters with an oil can before installation? If so need to buy an oil can.

          Dear Ernest,

          Thank you for your patience. In response to your question-

          It depends on what lifters or whose lifters you purchase. Some instructions specify priming lifters prior to installation.
          Some lifter instructions actually specify not priming the lifters before installation.
          We suggest S&S, Jims, or Harley Davidson lifters with S&S Quickie adjustable pushrods and pushrod covers.

    Good afternoon. I leave in brazil and I have a 2011 Road King 103. The noise at the valve seems to be at top of cylinder, it is really bad. I do not know if it is because of acohol content at our gasoline, or something else. I am really concern about it. Should I have to change the lfters? Is this noise normal? I really do not know waht to do here. Thanks

    Have a 2011 Road Glide 103
    absolutely drives me crazy
    The ticking noise is at full affect from 2k rpm to 2900 rpm
    installed those inserts for the top end rockers
    did absolutely next to nothing. Is there a certain oil to use that might calm it down ?

    I have the same issue with my 2010 103. It was very noticeable tick during a recent trip. I thought maybe I picked up some bad gas, and even changed the spark plugs, but the tick remained. Back to his question.. can you run maybe a cap full of seafoam without hurting the motor? If it is just carbon build up, is there a better way then tearing the motor down?

    I just bought a 2012 street glide with 25k miles The first 15 miles she ran quite. It then developed a ticking noise that’s gotten louder. It starts after about 7 miles down the road. I can shut it off for 15 min. Start it back up, no noise 2 miles down the road its back. Its louder than the ” Harley tick “. Thoughts ?

    2014 triglide 103 h.o. engine has developed a clatter, do not notice when idle, but when throttle up thru the gears and when I throttle up during regular riding. Has just started within the last month, bike has 21k miles and just a 3 hole fluid change still doing it. Dealership says it might be the flapper valve in intake?? But they said does not seem like it is internal. Sounds like valve clatter or an exhaust leak, but everything is tight.

    Ticket 18340 I had a HD SE 110 Kit installed n my 2013 Super Glide Custom at 11k miles. At my recent 50k service, the dreaded metal particles were on the drain plug. Changed oil after1 & 2k and more metal shavings. Dealer is hearing a noise coming from the motor. Dealer made a comment ‘that getting 40k was good’.. Any feed back on the S E 110 kits? Is the lifespan of a kit really about 40k?

    I bought a new 2012 Ultra Classic with the 103 motor and it ticked loud on cold start-up when temp. outside was at 60 degrees or colder. It only ticked for a couple seconds and stopped. When temp. was warmer it didn’t make any loud ticking noise on start-up. Dealer couldn’t find any problem with motor. I ran 93 octane gas and used H-D synthetic oil. I believe it could have been a weak lifter but why it only did this when temp. was cooler, I couldn’t figure out. Strange. I traded the 2012 in with 17000 miles on it for a new 2014 Ultra Limited with a 103 twin cooled motor and this bike has never made any loud ticking on cold mornings. Good to know I am not the only one who heard this noise with the 2012 and the 103 motor.

    My 1st time buying a twin cam engine. I’ve had evo’s for over 300,000 miles and shovels before that i’m looking at a 2011 103″ road king classic with 32000 miles. Any concerns or suggestions would be appreciated. I’ve heard all the stories about cam chain tensioners and have held off for quite a while but need to step up thx

      Don,

      You do not need to worry about cam chain tensioners for 2007 & newer touring models. The tensioners are hydraulic.
      Tires are expensive. This m/c should have it’s 3rd set of tires at this point. Also inspect rotors & pads & all electrical functions.
      If the bike has a performance exhaust and air cleaner, make sure that it also comes with an appropriate tuner.
