I have a problem with my BDK. I love this game but there is one thing that drives me a bit crazy. There often are dropouts/ball reflects from the gate behind the joker drop target. I tried to tweak it but the more I play this machine the problem getting worse.

If I have a fast ball that should go through the gate and then at its way back it should get stopped by the gate so the ball could fall into the lock I don't know if the ball gets reflected by the gate or if the gate is not closeing fast enough, but the result is that fast balls won't go into the lock.

The gate should close fast, there is a spring plate that should speed this up. And when I test it from hand it's good, only ingame I need 4-5 shots at the gate until the ball gets in the lock lane.

The problem is I don't know how I have to tweak it, so that the gate would behave the right way.
Thanks for your help.
