Lifters rattle
« on: August 13, 2019, 11:38:45 AM »

Question.... Recently (around 500miles ago) I replaced the lifters on the '15 CVO 110 as a pre-caution since the clock turned 25K. I replaced the stock lifters with a Vance and Hines hydraulic lifters and adjustable push tods.  Bikes was running great the replacement lifters sounded much smoother.
Move forward from my trip to Sturgis last week when I toy hauled the bike upwards of 1500miles I went to start the bike and it rattled like crazy I shut it down waited a minute and started it again.  Sounded fine so I rode it off and on for a few days with I think no problem.
So I tow home (1500 miles) push the bike back out of the toy hauler and start it to move up my driveway and it rattled terribly so I shut it down again waited a few minutes and started it again, it rattled a bit then quieted down to what I think was normal.

Any ideas?

Sounds like the lifters are just bleeding down when not running.  As long as the rattle stops just after starting you should be ok.  If it really bothers you though swap them out.

The ride in the trailer caused all the oil in the top end and the lifters to bleed down into the crankcase. So basically after each trailer trip it was like starting a brand new motor with no oil pumped through the top end yet.
I wouldn't worry about it unless it starts doing this just from sitting overnight.

 on my 16, change lifters w/S&S, same thing... park it when its hot and in the am tick, tick, tttttick. I call it morning tickness. did it with stock lifters also. 20k on each set, think im going with Johnsons next time... winter project. I think it has to do with the heavy springs HD uses  :nixweiss: . bike runs to good for me to justify changing cams and springs at this time, plus I love the monster torque of the 255 & the fullsac setup

Vance and Hines buys lifters does not make them. The spring pressure will bleed the best of them off even slow bleed Johnson's. The slow bleed is also slower to pump up with high viscosity oil.

I'l bet you parked it in the trailer in gear.  Bike bouncing and small movement back and forth bled down the lifters.
Don't worry about it.

Thanks for the consensus I took it into the dealer just to hedge my concerns with the rattle since I only had a few hundred miles on the new lifters.  They pretty much said the same as  you all....

You aren't the first person to have this happen after trailering the bike.  If you have the same issue after just letting the bike sit overnight, however, I'd suggest those lifters you bought aren't the greatest.  You didn't mention your stock lifters doing this, and Harley's "C" lifters are far from the best in this regard.  As Don noted in a previous post, the heavy valve springs in a 110 can lead to a lifter leaking down quicker, but all four valves aren't going to be off their seats at the same time.  One lifter having to pump up is noisy for a short time, all the lifters having to pump back up at the same time might scare the bejesus out of you the first time it happens and it's not normal or good.
