Valve Noise

[Shriner Jim]

What do you suppose could be causing valve noise in my 2008 Ultra-Roadsmith? The last couple of times I rode, the valve noise came in at about 2500 rpm until it was fully warmed up, then it was quiet. The oil is clean and pretty fresh, about 1500 miles on it. I use Amsoil 20W-50 and have exclusively since 5000 miles. I change oil and filter at 3000 miles, yea I know that's probably a waste, but I feel better about it. I now have a bit over 17000 miles on it. Any help or opinions are appreciated.

Here's your solution. Hands down the best and most quiet lifters on the market today. I've installed them on several bikes and they are as quiet as a church mouse. Stock pushrods or adjustable, makes no difference.

We have done side-by-side comparison on stock touring HD bikes same year and about the same mileage (20,000 miles). No more lifter or rocker arm clicking sound at start up, idle or when cruising.

Thanks Mr. Wizzard. I will consider these. It sounds like maybe the stock lifters are not holding until the engine is warmed up to operating temp. The problem just now started, however the noise seems to be in the top of the engine. I guess that the lifters not pumping up to the max would place the slack in the rocker area, thus the noise?????

Thanks Ultraboy.....lots of good info. Now I have a choice to make. Quite a difference in prices between AMS and Wiz's recommendation.

Update: Seven of us rode to Key West last week and returned this Wednesday (boy am I tired!). On two occassions, my lifters had leaked down and the noise was as bad or worse than before. It was only at start-up and quieted down after about 1/2 mile. I'm convinced that the noise is caused by the lifters leaking down. I am running Amsoil 20W50 and a Baisley Spring. The oil pressure is good, better than before with the stock oil pump spring. My riding partners all ride 2009 96" Harleys. They don't have this problem, although one has more mileage on his than mine. I am considering the Black Ops, AMS and Woods. The Woods are about $260 for a set, way high but are they actually that much better? Any experience out there?

After getting my FLHX Streetglide with an oil pressure gauge, I was shocked at how little oil pressure was generated at idle and at cruise! No wonder the lifters leak down..my oil pressure at idle was somewhere around 5 lbs., and at cruise I was lucky to see 35 lbs! I was not ready for that. I also used the AMSOIL 20w50 and had no problems...it has 12,000 miles now with no extra noise.

I had a 2010 TG in here last week with 11K miles on her. Stock trike 103.

Did the usual upgrades, TTS tuner, Fullsac X Pipe, Ness AC, but we kept the stock mufflers. Owner went Woods 555 cams, adjustable rods and HQ Black Op liters.

Forgot to soak the lifters before installing... is what it is...

Installed them anyway dry, right out of the box. I pulled the plugs and cranked her for about 45 seconds and saw oil pressure come up on the gauge then went back and adjusted the rods again.

When she fired up there was one tapping (exhaust rear). Within 60 seconds of idling she quieted down. Owner was impressed as to how quiet the motor was now.

Anyway... several test runs up to hitting rev limiter for the tuning she's back on the road. The combo of the Woods 555 and Black ops is hard to beat.


...btw.. hot idle at 5 pounds and cruise at 35 is fairly common Chris although I would rather see 10 pounds at idle there are more 5 pounder bikes than 10 if that makes any sense.

Besides a soak I normally take a pump oil can I have and pump oil in the hole on the side until I see air free oil come out the top.

A simpler consideration.
What was the outside temp the "last couple times"?
Did you let the motor warm up before you rode?
If it was cold weather-what weight oil are you using?
Cold weather = warm up for the motor w/lighter weight oil.

I have a lifter tick in the rear cylinder at idle with18-20 pounds (I run the hydraulic tensioner upgrade kit with the larger pump)....doesn't seem to matter. I have not been able to "adjust" it out, not a pushrod cover and no evidence of the rocker arm hitting the cover. It's not as noticeable with dino. I make the assumption it's slack in the rocker. I consider it a built-in feature and run the he!! out of it. I can't hear it at 75-mph anyway.
