I am not very adept at wrenching nor am I knowledgeable about engines. I try to do some things myself when they are simple enough. So my question is what is behind the Derby and points covers and if I replace them myself am I likely to get in trouble? Looks like a simple unscrew and replace job to me but are there any fluids behind the Derby cover? Also I am thinking of installing a Road Zeplin seat. What is involved with that? Will I need to cut and splice any wires or is it a plug in job? Thanks in advance for your assistance.
