Thanks GO and racefactor. I have loyally used Go engines from the beginning of my racing adventure and hope to have many more wins with the. +1 with Will G. Go engines by far capeable of domination other engines I cant wait for the ebm5 engine for my truggy. I am doing bearings and con rod and pins and clips in mine as per Russell to keep my 5 port (5+ gallons) in tip top shape. They are the only parts I need at thie time. I am only doing it cause the fromt bearing is starting to suck air and after 5+ gallons and that is fine with me that engine has spun prob 2,304,000,000 full rotations in its 128 tank life (think about that for a second) it is a rough guess as i did the math in my head so... anyway. Go engines and Russell of Racefactor are whre my loyalty will continue to stay. Thanks Russell I ran both my Go's this weekend and the 7 port is a monster in the buggy I love it and the bearing gave up the ghost in the 5 port in truck. Oh well Ill get em next time. Thanks again Darrin @ Brujeria Cutsom Graphixxx
