They do not do CADMIUM plating. What you had done was bright ZINC plating a totally different metal. CADMIUM is no longer legal due to toxicity of the chemicals.
If you have stock exhaust (notR3), then you can extract the starter without removing anything else. Slide it rearwards until the nose clears the opening, then tilt it down and the far end up.
The boost goes up as a square of the RPM. double the RPM get 4 times the boost. Up to a point when the tips of the impeller reach speeds where there are shockwaves, the boost stops. (The tips can actually break the sound barrier).
Often a poor ground on the switch will mess with proper wiper operation. Check by clipping a ground jumper wier from the switch case to a known good ground. Then if it doesn't still work try adjusting the park position tab on the wiper motor itself.
Did you not read where the pads have to be special and NOT the Bendix Type? Stock pads will NOT work with these pistons. You need the thicker backing plates of the new pads.
