Question about Razor MX350 DIRT ROCKET - BLUE
I have an older electric Razor MX350 dirtbike (101520-04-05090035507). It has sat for about 1 year and I have purchased a new battery. It then ran fine but over a short time always seems like it has a dead battery. Symptoms: 1. When I first attach the charger, it quickly goes to green. 2. When my 42 lb boy rides, the yellow light on the throttle comes on and it goes about 2mph for 50 ft. 3. When I take off the battery covers and measure voltage at the back of the connector with the red and black larger gage wires (maybe 10 gage or so), I read about 25 volts. So, I thought geeze, the battery isn't dead, the power just isn't getting through the controller. So.... 4. With the power turned on, I put my meter to the blue and brown wires out of the controller and throttled up while holding the bike still. I read a max of about 4 volts, but it quickly goes to 0 at about 3/4 throttle. The yellow light for low power remains on if giving throttle while loading the bike by not letting it roll. Do you think it may be: 1. controller 2. bad throttle 3. bad power switch 4. bad motor or something else.... Thanks, Joe

I would take it to a shop only because the tire has to be on almost perfect so there is no wobble.They have the proper equipment to make sure it is aligned properly.If you are going to go around 40-50 mph alignment is critical.Even jumping moguls and turning alignment is critical.
