I am running a predator class in a flat kart for the first time. 5000 rpm limit. i have my motor but i'm not exactly sure what to do to it to get ready, i know drill gas cap but how big of a hole? Also i know i delete oil pressure sensor but how? how to set governor to 5000 rpm limit? should i use just standard oil or the thinner stuff used in clones? and lastly do i run 87 ethanol or can i run higher octane? thanks in advance to all that are helping it is greatly appreciated
