Re: The valves are making loud ticking noise, thought...
Double check the tolerances, a loose lock nut on a tappet can make noise. Some times a bad or missing exhaust o-ring can cause a ticking sound, make sure you remove the old exhaust gasket and install a new one.

Here are 3 causes for lifter tick!
Bad Lifter, Dirty Oil Deposits, Bent Push Rod, The rocker arms will make a noise if push rod clearance is not adjusted right. God-Bless! and hope this helps you!or the rocker arms may be worn.
If there was a problem that caused the rocked to become dislodged I would have checked the rocker bushes and shaft and replace both. The rocker where it works on the end of the valve wears a recess that will move and then click back into place. I would use a 20w-50 grade oil and additives work at reducing friction . IF you need it to thicken the oil then there is something worn out.
IF you did not keep that rocker gear and rockers together as units then the noise may be from the wear on the ends of the rockers not matching the wear for the valve ends. If you fitted 1 new valve and did not grind the rocker arm wear out that may be the ticking noise
Hi, does oil reaches the rocker box abundantly ?
You must adjust the valve gap according to manufacturer speficarions.
Maybe you pressure release valve is set to low and you d'ont have enough pressure to reach the rocker arms
good luck
What does the "tick" sound like?? The R-RT is an air/oil cooled engine and some noise is normal. If noise is very loud, it could indicate a problem with valve train or any number of other things.
Does noise stop when you pull clutch in with trans. in neutral?
When were the valves last checked/adjusted? Was rocker arm end play checked as well as valve clearance?
The only thing under the rocker boxes is the rockers and the upper part of the heads with the valve springs. Getting to this area is not that difficult.
Remove the fuel tank and seat. Then, remove the six bolts that holt the top and middle rocker box covers on. Now, you're at the rocker plate with the rocker arms in it. You can also see the tops of the valve springs. Look and see if there is anything that might be causing your noise.
Now, keep in mind that a Harley engine is of an old design. It is a pushrod type engine with rocker arms that open and close the valves. They are going to make a little noise. Now, if you're having to get close to the rocker box to hear the noise, it's probably nothing to worry about. But, if you can hear the noise stand away from the bike a few feet, you may have a problem. But most things that might break or come loose under the rocker box will usually effect the way the engine runs.
Also, you could have an exhaust leak. It makes a "tick, tick, tick" type noise. Tighten the nuts on the two studs snugly but don't break them off.
Your ticking noise could be most anything. You didn't tell me how many miles are on your bike.
Now, on top of the head you have the typical stuff that's on all four cycles engines with pushrod operated valves. You tappets down below that push up on the push rods. The push rods push up on the rocker arms. The rocker arms pivot on rocker arm shafts that ride in rocker arm bushings. The rocker arms push down on the valve stems that are closed by valves springs. The valves are also guided by valves guides. There could be wear in any one or more of these places causing the ticking you are hearing.
Now, whether or not the ticking warrants concern is how loud the ticking is. If it something that you have to "listen" for, I don't think I'd be too concerned as a bit of valve train noise is common in an engine with a few miles on it. However, if people are asking you what's that noise when you pull up, you need to have it checked out.
Pull the top covers off the heads and check for broken valves springs, missing or busted valve keepers, excessive wear in the rocker arm bushing. I hope this helps, Good Luck and ride safe.
No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.
