Lifter noise on '05 117"

[PackedFunk]

I'm helping a friend with his '05 117" S&S Big Dog.
He complains about excessive ticking lifter noise. I told him that some fast open/close cams cause this. He is wanting to change rocker boxes to try to quiet the noise. Someone told him some thicker ones will help. The pre-load on lifters has been set to 3 turns. Are H-D EVO Rocker boxes interchangable with 117 S&S engine. Thanks for any help.

Don't know if the HD covers will fit the S&S motors but the reason BDM used the TP covers on the 05 models was due to there being more quiet as EPA standards are not only exhaust noise but mechanical noise also.

Many here have replace the TP covers/rockers with the S&S ones but that's about a $1000. Mine are running very quiet and I've not had an issue with the noise so may just need a good adjustment.




By the way, there are a lot of theads here on this subject!

hd twin cam fits

its an EVO lower and TC upper

go another 1/2 to full turn on the rods (more preload)

Yea, what Marv said! Big Dog suggests going 4 full turns for pre-load.

As for the rocker boxes, TP have been known to have a slight geometry issue and don't hit "square on top" of the valve, sometimes causing valve guide wear or even valve failure. The S&S seem to be the choice of those who do change. I think BDM uses S&S now on all bikes. Even Rays rocker boxes appeared to have some valve guide wear on one of the valves when he recently rebuilt his motor. See pics in his thread.

'05 117 Big Dog

My friends '05 117 S&S engine does NOT have twin cam heads. They are EVO type heads & rocker boxes. I own both a H-D Evo & 96" twin cam & know the difference. There are only 4 allen heads in each rocker box top, making it EVO STYLE.
This "05 Big Dog only has 5000 miles on it & has leaks everywhere from engine & Baker 6 speed transmission. Starter has failed, ignition problems, wiring problems, signal lights have failed, S&S carb. problems, cracked motor mount, primary has developed a crack, & on & on.
It is easier to list things that haven't had a problem.
Any one else have a lemon such as this???:angry:

Never heard of those problems on a Big Dog. I over filled the gas tank one time and got gas on the tank, but it soon dried.

It's not an HD engine either!!! It's as stated S&S SSW+ (SuperSideWinder) engine and S&S went to the twin cam breather system on their motors in 05. It's all on their website for you to check out.

From the S&S website:

How does my new SSW+ breath?

In many respects, S&S SSW+ engines are similar to Evolution style engines, but when it comes to the way they handle crankcase venting, they are a whole 'nother animal! Most S&S Evolution style and SSW+ engines have two engine breathing systems that can be used separately, or together, commonly referred to as case breathing, and head breathing. For case breathing, SSW+ engines still uses the venerable breather gear to regulate the engine's internal airflow, just like the Evolution style engines before it. However, the head breathing arrangement is markedly different. SSW+ engines don't use hollow breather bolts to vent excess crankcase pressure to the outside. Instead, the head breathing arrangement of a SSW+ engine consists of two hoses - a small hose on the front head, and a larger hose, equipped with a one-way check valve on the rear head. (More on the check valve in a minute). The front hose is routed from the front head to the intake manifold. It applies manifold vacuum to the crankcase anytime the engine is running. The rear hose is routed from the rear head to the carburetor backing plate (or other suitable location). Its purpose is to relieve excess crankcase pressure at all rpm's. Unlike the hose on the front head, the hose on the rear head doesn't do anything until pressure builds in the crankcase. Just remember, the front hose sucks, the rear hose blows. The rear head breather hose on an SSW+ engine performs the same function as the breather bolts on an Evo engine; that is, venting excess crankcase pressure to the outside, without allowing outside air back in. Both engines use a check valve to perform this function. Evo engines use a pair of umbrella valves located inside the rocker boxes, while SSW+ engines use a one-way check valve, S&S Part #50-8122. It is located outside the engine, placed in the aforementioned rear head breather hose. The one way check valve must be used with the rear head breather hose, no exceptions. (By the way, SSW+ rocker boxes will have provision for Evo style venting, but it is not functional). The front breather hose supplies vacuum to the crankcase as added insurance against engine blow by. In most applications it is beneficial. However, there have been a few cases of this hose pulling oil into the intake, causing the engine to smoke. Using the front hose is optional. If the front hose is causing a problem, it can be removed and the fittings capped. If the front hose is removed, a check valve is still required in the rear head hose. The one-way check valve is critical to the engine's operation. It must be installed in the hose so that air can flow out of the motor, but not back in. The valve is light colored on one end, and black on the other. You can blow through it to determine which end faces the motor, or, if you'd rather not wrap your lips around the thing, just remember--"black out"-- the black end always faces out, or away from the engine.

Ray,
Ever since you jumped someone's ass for not doing a proper introduction, you've gone soft. Mamma must have jumped that ass and cut you off for being a meanie!

Dude, your mixing me up with others. Im not the one that makes the introductions such and important part of being a member here! Same with the reflectors and stickers. :2thumbs:

I ... know the difference.

clearly you don't.

I think putting an 05 in the vintage section is a touch harsh too
