Could be as simple as a mal-adjusted pushrod... but I'm certainly no authority in this forum. Will sub to the thread. For what it's worth: pushrod actuated air-cooled engines are supposed to be noisy like a 1920's sewing machine. I've got an angry one in the garage.

I found that when I went to adjustable s&s pushrods they would touch my stock pushrod tubes. Causing a tick. I chased my tail doing rocker lockers which helped but didn't kill the tick. I even shimmed the rocker arms to take some of the slack out. Added half a turn on my pushrod adjustment.

thank you I will take my covers off and see I did take out the webbing where they said to in the instructions for the roller rockers.
Not sure how different the covers are from 09 to 15 . I am running the same cams in my 15 rgs with my 107 build and didn't have to clearance the covers.

Are you running new rocker plates with S&S Roller Rockers? The arm for the valve is a lot higher in the forging to increase the support for the roller.

Checking for witness marks on the underside of the rocker cover is a good idea. However, Wood cams are know to have faster ramps; roller rockers are noisier than OEM and if stiffer valve springs were used in the heads, what the OP is hearing may be just a case of "it is what it is"; didn't sound alarming to me.icon-wink:
