Quoted from quazimodem:

Pop bumpers
They work but not as well as one would expect. It seems to work only when it is hit on specific angles. Often times, doesn't even pop at all.

They probably just need to be adjusted. Make sure the actuator is perfectly centered in the spoon and that the switch gap is close but not touching. This is an excellent video that explains the basics of pop bumper adjustments ...

Quoted from quazimodem:

Star rollovers
Working as well, just has to go exactly over the middle of the star roller to register.. is that normal? Would like it to be a bit more sensitive.

Check to see if there are capacitors on the rollover switches. If they are not there, or if one leg is cut (see photo below), you will want to buy some new ones and solder them into the circuit. The capacitors help the game to register very brief switch closures. What is probably happening with your star rollovers is that the ball is moving over them too fast for the game to sense. Of course, you should also make sure that the switch is clean and properly gapped.

You may also find that your standup targets don't register quick hits either. There should be capacitors on them as well. Here is some more info on the subject ...

And here is a link to the proper capacitors ...

I also forgot to mention that you can check to see if a switch is working properly using the stuck switch test. It's option 94 in the menu.
