hi names michael . My tanaka 47 r motor on my golden egale set up has pushed me to 47.8 mph. Tuned pipe ,boost bottle ,advanced timeing key, 91 octane chevron gas, 46 to one tanaka oil mix.Tanaka Best motor ever built!! Jemma read couple of your other threads don't cut your tuned pipe, get a tuneable walbro carb ,allso advanced timeing key.Your tuned pipe has been set up allready for your engine size. changing length in manifold length will ruin everything!!! Get a tuneable carb.
