I have Aquin 250cc. I bought it not going. I got it going and it ran for a week, but stopped all of a sudden. it has spark and petrol is getting to the carbs. Have by passed the kick stand switch, but still nothing. Can you help.

To change your oil filter remove oil drain plug drain oil into an oil pan clean and replace oil drain plug, then remove oil filter, pour a drop of clean oil onto a new oil filter, and lube gasket, then replace the old oil filter with the new oil filter. Finally, add clean oil to the motorcycle until the oil level window shows oil in the middle of the viewing window when the bike is upright. ,,,

You may want to try a 'color match ' polish.Try your local Detail Shop to get the best suggestion as to what they use.

Under well-lit conditions look for any signs of punctures (such as nails or shards of glass) which might potentially lead to a loss of pressure or a blowout. Bulging or cracking might also occur on old tires; make sure you roll your bike forward in order to see all surface areas that come in contact with the road.,

You may just need to locate the idle adjustment and turn it down a bit.

Check the drive belt for wear. If sides are worn you will not reach top speed.

Some common causes and potential solutions: Air/Vacuum Leak: If your Harley develops a vacuum leak in its air intake system, the air-fuel mixture becomes too rich. This can cause frequent stall outs, especially after the bike warms up. Vacuum leaks often occur due to dried-out or cracked air intake boots, faulty gaskets, or worn-out carburetor seals. When air escapes from the intake system, the fuel fills the empty space in the combustion chamber, altering the air/fuel ratio and negatively impacting combustion. Severe vacuum leaks can lead to excess fuel flowing into the exhaust system, causing backfiring and stalling while riding. Clogged Fuel Tank Filter/Fuel Injectors: A blocked fuel tank filter (due to coagulated fuel, moisture, dirt, or corrosion) impairs fuel flow, resulting in a lean air/fuel ratio. On fuel-injected Harleys, clogged fuel injectors produce similar symptoms. Regular maintenance, including cleaning and inspecting fuel filters, helps prevent these issues. Faulty Cam Chain Tensioner: A malfunctioning cam chain tensioner can affect engine timing and cause stalling. Regular checks and replacements are essential to avoid this problem. Faulty Cam Position Sensor: The cam position sensor plays a crucial role in ignition timing. If it malfunctions, it can lead to stalling and backfiring. Clogged Air Cleaner: A dirty air cleaner restricts airflow, affecting combustion efficiency. Regularly clean or replace the air filter to prevent this issue. Ignition System Failure: Faulty ignition components (such as spark plugs, ignition coils, or wires) can cause misfires, backfires, and stalling. Inspect and maintain these parts regularly. Compromised Battery Terminal Connection: Poor battery connections can disrupt electrical flow, affecting the ignition system. Ensure clean and secure battery terminals. Remember that diagnosing and addressing these issues may require professional assistance. Regular maintenance and timely repairs can keep your Fat Boy running smoothly on the road.

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.
