I'm in the process of improving my BK. I've noticed, in playing it, that when I hit a few of the targets, that some have a harder time dropping than others. Is the best way to fix this simply removing the target enclosure and cleaning them? Is that what causes them to stick "up" before falling with a harder hit?

See these pix for shots of the targets after they've been hit, but before falling.

I'd take them apart and clean them, making sure they slide freely in the plastic channels. Consider replacing the small coil springs and check that the large leaf springs don't have too much pressure.

Thanks. What do you recommend cleaning them with? I know that stuff like WD40 is anethema - what do you recommend?

I usually clean those with some windex or simple green. No grease or wd40.

There is a metal strip attached to the back of each drop target that holds the drop target in place. After cleaning them, you might try bending that strip inward just a bit to allow it to fall a little easier.

Must be a common problem, mine is doing the same thing. I also have one target that causes the machine to tilt when it drops.

I had this cleaned them all out, replaced the copper T slides at the rear.

Also got the target art and printed to decal paper and re-did the decals. Spray of clear coat on them. Looked nice.

Sounds like a switch matrix issue. Start another thread and someone will give you a hand with it.

yeah you gotta pull those out, take them all apart and clean them. i usually drop the parts in the utrasonic for 15 minutes and hit them with a toothbrush. you can use a degreaser like simple green or lightning and a toothbrush if you dont have utrasonic. when you get them all clean hit the surfaces that are making contact in the sliding motion with some cleaner wax and make sure you get it all off. this will make them drop like silk.

Well my boards are being repaired right now so I can't tell you how they play just yet. Hopefully I get them back soon and then I can report.

I had that problem on one of mine after being stored for a while.. I have a friend who used to repair pinballs for a living, and he suggested cleaning the metal where it contacts with some steel wool, and then loosen the screws holding the bar that goes across them all just ever so little.. I did it, and it works great now..

Good luck!

I used 1 drop of synthetic oil where metal meets metal - the drops are snappy now. New springs didn't hurt either.
