What did the old spark plugs look like? This is the first place to start your diagnosis. This does not sound like a motorcycle.

no you dont need to bleed system, sounds more like youve knocked off a wire under the tank

Is there a shut off valve at the bottom of your tank? Possibly you shut it off and just forgot to open it . When you drained your tank, did you rinse out the inside with gas, to make sure the screen at top of shut off valve was not clogged. Is the shut off valve clogged? If there was grime in your tank it could have gone past the shut off valve to carburetor, causing a clog. You may have to do some cleaning, take your time. GOOD LUCK FRIEND.

Parts department should be able to advise about this

You'll have to remove the plastic around the ignition switch. There should be 3-6 screws holding this in place. Once removed, you will see that the ignition switch has a holding screw/bolt on each side (2). Once removed, the wiring will have a connector that needs to be disconnected. You can now install your replacement, connect wiring, two bolts, test ignition before replacing the plastics...

The fan should come on after the temperature gauge pivots past a certain point. you can unplug the fan and run a wire from the hot (red if showing) wire to the positive battery terminal.

Sounds like an ignition failure replace the spark plugs first ....then check your crabs by opening the bleeder screw at the base of the crabs if trashy gas comes out,, clean the carburetors..

Need wire colores for mini chopper

is it running ? could be the water pump or thermo state

Kill switch is likely burned out and needs replacement.

you have a fuel blockage problem. The fuel gets into the carby slowly and allows you to start but the rev increase is an indication that the air/ fuel ration is going lean and then the motor stops. The same as if you turn off the tap and let the engine run until it stops. It won't start again until there is sufficient fuel in the carby bowl to get to the main jet.

Whoever sold it to you gave the bearing a shot of heavy oil then smiled as you drove away. The engine has to come out and the center case has to be split apart to gain access to the bad bearing. This requires some special tools. Your best bet is to trade it in on a Honda scooter. At least you can get parts and service when you need it. I am really sorry you got ripped off. Some people have no honor.

I have the same scoot.Use premium gas,change oil monthly,replace spark plug often.The best info and prices on parts I have found is scrappydogscooters.com, also you can buy a cd-rom off e-bay that has all the info and diagrams you could ever need for your GY6 139QMB engine. Good luck!

I can't find a diagram. The small potentiometer on the control board likely serves as an adjustable component to fine-tune specific parameters. Here are some possibilities: Voltage Regulation: The potentiometer might control the output voltage. By adjusting it, you can set the desired charging voltage for different battery types (e.g., 6V or 12V). Current Limit Adjustment: It could be used to set the maximum charging current. Adjusting the potentiometer allows you to limit the charging current based on the battery's capacity and condition. Sensitivity or Threshold: Some potentiometers act as sensitivity controls. For example, it might adjust the threshold at which the charger switches between charging and maintenance modes. Setting the Potentiometer: Without the specific circuit diagram or detailed information about your charger, I recommend the following general steps: Observe the Potentiometer: Identify the potentiometer on the control board. Note its position and any markings (if present). Consult the User Manual: Check the user manual or operating instructions. It might provide guidance on adjusting the potentiometer. Trial and Error: If no specific instructions are available, start with the potentiometer set to its mid-position. Gradually adjust it while monitoring the charger's behavior (e.g., charging current, voltage). Observe how the charger responds to changes in the potentiometer setting. Fine-tune it based on your specific battery type and desired charging characteristics. Remember that precise adjustments depend on the charger's design and the battery you're charging.

The lift cables on a 1993 model 2693 Hilo camper are 30 feet,2 3/4 inches long and fit the standard height lift of 11 feet 8 inches high to the top of the overhead. The lift uses two cables. According to a Hi- Lo camper travel trailer forum, cable replacement is basically the same on all years and models, with the main difference being the length of the cables from model to model. You can use a cable cut chart to find what cable length you need for your camper, and you'll need to know your year, model name, and box (body) length: Lift cables typically wear out after three to five years, so it's important to replace them as needed and keep them regularly maintained.

Check fuel delivery ,or fuel filter

The bike doesn't exist as written. https://www.google.com/search?q=410JS+1000cc+santana We are better with 'year make model 1000cc'. Better to not try and do better than the bike engineers. A mechanical pump runs when the engine is turning, an electric pump will run as soon as the key is turned and create pressure all the time. It would have to be an in tank electric pump or it will burn out. Electric pumps are cooled an lubricated by the fuel passing through it. If it is a carbureted engine, you are pressurizing the carb bowl. If injected, it may already have a fuel return. Check the mechanical pump for a torn diaphragm, they are easy to change. ..
