help please and sorry for the novice question.
i recently changed from stock to tekin 5.5 motor. initially used the stock 18T spur gear and it heated up. than changed to 14T and a lot cooler but it seems i have a lot less power. struggle to clear triple jumps. with stock did it easily.
its nice its sensored so a lot smoother throttle but lost power.
advice? thank you in advance.
