help needed

I've got a motor issue. When pulling my trailer with my King Hauler(55t motor and 9 tooth pinion) when it gets into a little strain going up slight incline the motor starts cutting out. This is in 1st gear. Any suggestions as to the problem. I never noticed it with no trailer

Mine kinda does the same thing,I just give it more throttle. I have the same set up 55 turn and a 9 tooth gear. With 50#of load I really have to throttle up on an incline. (my daughter sits on the trailer)

Re: help needed

how much more mods are needed for a 6tooth? the 9 tooth needed a spacer between the motor and trans, but i may need to re adjust mine as i get a geary noise in first gear.. idk
