Any pics of these new engines? I raced my A52 for the first time yesterday with the 801 pipe. The motor performed great had awesome power tons of bottom end. Had 2 flame outs in heat race changed from OS P3 plug to Werks 5 plug and problem solved. Too bad its may be my last race of the year with it. I Look forward to getting another one of these mills for next years season.
