2003 Hyosung GV 125 Aquila - Page 4 - Answered Questions & Fixed issues

Hyosung used a very bad quality side stand switch on some models. I just removed the switch located at the stand's pivot and short the leads to bypass the switch. Note that you are not protected by this safety feature any more and must be very careful not to ride with the stand down. It is not a big deal and you get used to checking that as you become a better rider.

check air filter, spark plug and fuel delivery in that order. then check for plugged exhaust, valve adjustments and then timing. in the mean time answer these questions. is the gas fresh and from a known good source ??? did you do anything to it recently ??? is the engine revving high while you are moving ???

yes it needs a ground try welding it or jb weld or zip ty

Is your bike a fuel injected? if yes most chances are a faulty fuel pressure valve.Just enough fuel to idle but when you open throttle it will choke(starve)and die.Carburated? Main jet clogged or a Mal adjusted float height

Check vac. Reading. Am thinking you will show very low vac. Check yr crank to cam timeing i bet yr out of time

Hi there. Are your carbs balaced? The detonation causes a similar sound

Use a multimeter and monitor the kill switch or whatever switch shuts the unit off normally. It may be failing when warm. Sounds like you covered the basics already.

Sounds to me as if you've bleed over between tach and speedo.Maybe a wire cross and touching between the two.Possibly a Faulty pickup on the speedo too.

im not sure on the gear indicator, but your main bearing might be too tight or need lubricating. sorry its not much help

It is possible to rebuild anything that a human has put together. The real question is, Is it worth it? You can get a service kit and rebuild it that way. But, it would depend on the reason for the failure of the pump.

Tune up.

It seems there is fuel starvation when you reach that speed or the spark plug seems to fail.(1) Check the spark plug and also see if it's of a correct specs per the manufacturer's recommendation.(2) There could be a blockage in the carb's main jet which restricts the flow of fuel at that speed.Hope this helps!

Assumeing you have been trying to bleed the brakes and assumeing you tried that because your brakes quit working. Check a couple things. First try opening the bleeder first then pushing the peddle and see if fluid moves. Next make sure the piston in the master cylinder has its full range of motion ( not a lot of slop in the pedal at rest ). If you have these symptoms then you likely need a master cylinder rebuild. If you keep losing fluid you have a leak, and if you just changed a a bunch of stuff then its start at the beginning by bleeding the master cylinder.

If you have a battery charger, remove the battery cover to expose the battery terminals then you can connect the battery charge to the battery.Make sure you connect the positive lead from the charger to the positive terminal on the battery and the negative lead from the charger to the negative terminal on the battery before you power up the battery charger.When you have finished charging the battery, power off the battery charger before you disconnect the leads from the battery.

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.

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. ..
