Installed the roller rockers...
Tick, tick, click, clatter, they're installed along with forged supports. Got a little spit back from the throttle body this afternoon on a start-up. I'm wondering if I'm going to have to go back in to install some adjustables push-rods. The solid push-rods never actually became finger spinable, too tight?

RE: Installed the roller rockers...
08CVORK,
Let me know how this turns out would ya? I'm curious about those adjustable push rods (kinda skepticle actually). I've never dealt with them, so I have zero knowledge, but I'm considering a set of Andrews geared cams in my 06 softail & had still haven't decided on the pushrod end of things. Thanks

RE: Installed the roller rockers...
The '06 cam drive is fine - re-engineered from the 'silent chain' (hard to rotate) system. The tensioners were the problem with that system but the '06 has a roller chain and is much easier on the tensioners and bearings. You can find great cams for the stock system now so if you wish to avoid all of the tribulations of setting up the gear driven cams, leave your system alone....Adjustable pushrods are a basic pain in the butt because of the need to adjust them to start with. The procedure to correctly get them adjusted is much diddling around on a good day!
I chose to install Screaming Eagle roller rockers for the simple reason that the geometry is exactally the same as the stock rockers therefore I could use the stock length solid non-adjustable pushrods. In this situation, I'm looking for source of the noise - tick, tick, tick, that this engine has had from the assembly line and shimming, then replacing the rocker arms is to that end. Evidently the rockers were not the problem - now I'm headed down the system to the pushrods thinking that the stock ones may not be quite right.... that's all.

So your telling me my 06 cam chain setup is different? Are you 100% sure? I hope so. So, are there still teflon shoes...or do the use a tensioning sproket of some type? If it's still plastic shoes...wouldn't you still have the friction of a chain sliding over plastic? Also, are the 07s/08s the same setup?
Thanks for the info dude

Yes totally sure and yes the '07 and '08's have the same set-up. The tensioner plastic is a hard polyester similar to the earlier ones but a different material. They are also hydraulic tensioned with lube oil pressure, not just spring loaded. The tensioners are still a wearing part but not as severely worn as the pre '06 models with the 'silent' type of chain. The service interval is greatly increased.

Thanks, I did clearance the covers. I was wondering about the pushrods....My best bet is to go back in and install these Crane Cams adjustable pushrods. The fact that I could never rotate them with finger pressure worries me - as if zero lash....

If you put in adjustables, get the turns per inch of the threads on the pushrods. Then when you install them and set them to just contact the lifter [lifter on the base circle of cam or engine at tdc on compression for that cylinder] you will know how many turns down you have to go to preload the lifter .080 to .100 in.
Example: 24 threads per inch will give about .041 in per complete turn of pushrod adjustment.
32 threads per inch will give about .031 in per turn.

RE: Installed the roller rockers...
I went so far as to install and adjust the adjustables, lift the rocker assemblies, remove the push-rods and measure the length. They came out identical to the nonadjustables, I and E. The adjustables are Crane Cams, have metric threads and look very close to 26 TPI (.038" pitch so 2.6 turns). The solids are correct so don't need the aggrevation of adjustables. They are working fine and along with some Lucas 20W50 synthetic (had some 50W mineral in it), the noise is almost gone. Roller rockers aren't as noisey as some folks say, at least in this engine they work almost silently (as they should). The intent is to put some miles on this application before a judgement is made. Thanks for the advice, appreciate it!
