hey everyone wondering if i can get a little advice.Im running stock 17.5,with the timing on the motor turned up a little passed center,and nothing in the speedo,Im geared at 76 28 for a indoor clay track....westcoast raceway,and im coming off the track close to 185 degrees for a 5 min main....wondering why its getting so hot? Also I use those protek 70 c 6400 mah batteries,and I notice that after about 5 laps I dont have the same punch as from the start,could it be these batteries,or that the motor is getting so hot that is loosing a little power?
