New to clone engines so bare with me...my 11 yr old son is running a 2016 QRC Intermediate Wing Kart with a blue plate clone motor (came with kart so don't know much about it) on a 1/5 mile oval dirt track with very slight banking in curves. Weighs 324 driver & kart; running hooiser treads; & bully clutch. Per the mychron 4, it isn't getting over 5000 RPMs during a race no matter what gearing we have tried. What gearing would you try with the information listed above. I am pulling it to have it sent off to be refreshed now that the season is over but would be grateful for suggestions.
