Quoted from speederice:
Joining the club shortly (just waiting on it to ship). Is there an index or key post of must-have mods that I should seek out first? I know ColorDMD is on the list now....
For Premium/LE (most apply to Pro):
Adjust height of drop targets
Adjust spring on drop targets (20-25 coils up)
Check & change balls
SLIMER butt nut - check slimer positions and butt nut
Put a washer under right ball guide (blue rubber bumper) to help playfield damage
Put mylar down - where the ball lands when shot out - shooter lane. Or install Cliffy's
Get the green spring for the manual shooter rod, and the high compression spring for the auto-launcher
Install the plastic air ball protector and right orbit protector (CPR9999 makes the best!)
Adjust the coil power in the service menu ADJ > G.B. > Feature Adjustment #11 - Trough Eject Power. Mine is set the lowest power 176
Check 14th street subway switch to make sure ball is changing switch state
Ball guide rod 1/4" higher - hit with hammer (behind each sling shot area - this prevents ball jumping in the drain areas)
Hex spacer 1 5/8" (or 1 3/4") - change this on the right plastic 1/2 circle ramp (this shorter hex makes it easier for ball to go up).
