have a 2003 roadking with a 106 kit. Put the harley screaming eagle stroker in it and the new s&s 106 top end with Branch heads. Have Bob Woods 408 cams (650 lift), what Bob recommeded. Also have his new directional lifters, s&s roller rockers, and the red billet rocker arm support plates that gary williams makes for bob that move the pushrods inward to keep the pushrods from hittin the tubes and correct the geometry and a 55mm HPI throttlebody. Runs very well. 120hp and 121 tq. However at 50 mph it sounds like a little man is inside with a hammer. At 60 mph it gets worse. At 70 mph even with the stereo up it sounds like that little man is beating his way out of the heads. Is this the normal Bob Woods cam noise others talk about or is mine as I have discribed it worse.

Thanks for the info. the front cam thing you talk about makes sense. I will ask those that are more able then I. IF this can fix it I will go gear drive. If that will take half of the noise away I will be pleased, and can live with that. It's just when it sounds like it's ready to come apart makes me uncomfortable to say the least. If this is the fix it's going with billet cam plate and gear drives. I guess Gary Williams will know. Again thanks to all.

Before you go chasing this issue , i would just throw a set of other cams in like ss 625 or something cheep if its quite you have answer , i had woods tw8g did every thing tried every lifter, did every shim , tried diff. spring rates no help , fast closing exhaust ramp speed is the issue, there are other cams that do have power and are not as loud, Tman has a bunch, i am not bashing woods because i still feel his cams hit the hardest , and i loved the TW8G , the TW9b seems to be quite enough for me , in my 116" but just save time anb money test another cam if its quite and has same or close to same lift and TDC lift you have your answer.
His carbs go on Reher-Morrisons engines or at least they used to. Interesting to see some of the car and snowmobile guys are into Harleys also .

I have the woods 408-6 cam in my 117 and it is very loud. There is nothing u can do to quiet it down. Do like others said change cams to a diff brand is about the only thing I know of.

I have the same cams and 117" motor with big heavy valves and 188# valvesprings and the only time I hear anything more than a slight tick is on the hottest of days in traffic. Very quiet overall

I bought a 2008 FLHTCU that the previous owner had built. He had the TW8G cams installed along with going to 103. I have been riding since 1968. Many different Harleys through the years. Even worked for a couple dealerships and had my own shop for a bit. Did nothing but speed work on shovels and evos. This is the noisiest cam set I have ever endured. I even called Bob Wood, and he just said check the pinion runout. What? I like the idea of swapping cams and seeing what I can come up with. I do not trust this engine for a long trip or even a 500 mile ride. It is back at the dealership at this time and I want them to make it right. I talked with the salesman today and he is going to get on it Monday. If they can't fix it I will be getting a different bike. Too bad I really like the looks of this machine but cannot stand the noise!

I ran the woods 8 in my own bike couldn't stand the noise, swapped out to the very similar Tman 590 silent ramp design cam, lost a little peak power but have better roll on power and a small amount of valve train noise.
I finally have my woods 408-6 cams running pretty quiet. After putting woods lifters in, that cut the noise in half almost. Then, I put my TP rocker boxes and Jims roller rockers on. Noise reduced half again. Finally, I recently installed a Feuling race pump and plate, it sounds great! Woods lifters rattle a bit when cold, after a few miles, they do the job.

They didn't fall off, they got blown off.
