At one time there was to be a 2 step cam. It had 2 lobes side by side and it would move to open the valves more for more power and run on the other lobe for cruise. It may be the solenoid that would move the cam.

My lawn had rosebushes and the rider mower tires had lots of stickers and about 3 ounces in the front and about 5 ounces in the back tire took care of most of the problem BUT the tire stores don't like to work on a slimed tire.
From past info "All Elios come with the production fenders, If you want the RETRO fenders they will be extra" You will have 2 sets of fenders for Your Elio.
