Sticky Secondary: what problem could this cause if any?

[F-22 Raptor SHO]

This is one of those "I know cause before I know what the problem is"

I just painted a spare intake I purchased over this past week (they look good BTW) and was assembling it in my living room when I noticed something that may be a problem later: my rear butterflies seem sticky. They close ok by hand, but they dont snap all the way open like the other secondaries do, rather they just ease their way open (like either there is paint on a moving part, or the spring is weak). This would affect my secondaries above 4 grand opening as efficiently as they could. Now I know vacuum holds these closed until 4000 when the vacuum is removed and the butterflies snap open under spring tension. Dont know if the air pressure would force them open any quicker than the spring tension, or if the engine relies totally on the spring tension to snap the butterflies open.

Here are some observations:

1: I dont think there is any paint on the moving parts as I was careful to tape them off. I am going to take the actuator arm off tonight and see if the butterflies behave differently.

2: The 2 holes on the diaphram (one underneath and one on the ******) are not plugged, at least not on the outside.

3: I cleaned the butterflies with Berrymans prior to painting and just lubbed the butterfly shafts with some Pb blaster to see if that helped...it didnt.

Question: anyone ever have this happen before? I dont even know if this will be an issue, but if the car doesnt run perfectly later (or seems sluggish as it goes past 4000 rpm), that this could be the cause.

Thoughts?

I had the same problem with my set of rear secondaries. Mine would either open very slowly or not at all, so I just kept spraying wd-40 or any type of lubricant in the opening where the shaft from the actuator attaches to the secondaries. Then I worked them back and forth by hand several times which seemed to loosen them up and now they work fine.

and the SHO/Borg Collective has paid off once again with experience teleporting from Canada all the way to me in Arizona. I will give this a try. Dont know if this was a problem that the previous owner of this intake had or not...all I know is my intake is nice an' purdy'...probably wont work worth a $%#$@ but I will be the best looking car on the side of the road waiting for a tow, thats for sure.

any other comments from the collective?

Check them once you have them bolted to the intake. It may be that the metal is sprung just a bit and bolting it up will loosen everything up. Try spraying or dripping something like Tri-Flow teflon libricant onto the shaft. A local bicycle shop will have it in a drip bottle for less than $5, and it works wonders. You can also use it on your throttle cable, clutch cable, sticky speedo cable, not to mention many other things around the house. Its like 3-in-1 oil, but better

Would it work on a sticking cruise cable or is that being too hopeful? shrug This is not a necessity (I have it disconnected right now because it sticks so often) but I do like having cruise control for the highway.
