Your description sounds likely an exhaust valve is leaking.

if it stops when you turn the fuel tap off then i think your carburater floats are faulty maybe a hole in them

It is a 4 valve, 4 stroke engine so only one of the strokes has both sets or valves closed. The is called the combustion stroke. With the spark plug removed you can turn the engine at the crankshaft bolt. Drop a pencil into the combustion chamber at at TDC you will see the pencil rise to its highest point before it starts to go back down. That is when you measure the valve clearance.

If your 2002 Honda VTX 1800 loses power to the wheels when it gets hot, it could be due to several potential issues. Here are a few possible causes to consider:

1. Overheating: Check the cooling system of your motorcycle, including the coolant level, radiator, and cooling fan. If the engine is overheating, it can lead to loss of power. Ensure that the cooling system is functioning properly and that there are no blockages or leaks.
2. Fuel delivery issues: When the engine gets hot, fuel delivery problems can occur. Check the fuel system components, including the fuel pump, fuel filter, and carburetors (if applicable). Make sure they are clean, free from clogs, and functioning correctly. If necessary, clean or replace these components.
3. Ignition system problems: Heat can affect the ignition system, leading to weak spark or misfiring. Inspect the ignition coils, spark plugs, and spark plug wires. Ensure they are in good condition and properly connected. Replace any worn-out or damaged components as needed.
4. Exhaust system obstruction: A partially blocked or restricted exhaust system can cause a loss of power when the engine gets hot. Inspect the exhaust pipes, mufflers, and catalytic converter (if equipped). Look for any obstructions, such as debris or carbon buildup, and clean or remove them.
5. Clutch issues: If the clutch is not engaging properly when the engine is hot, it can result in a loss of power to the wheels. Check the clutch assembly, including the clutch plates, springs, and cable (if applicable). Ensure that the clutch is adjusted correctly and operating smoothly.
6. Electrical problems: Heat can affect electrical components, leading to intermittent power loss. Inspect the wiring harness, connectors, and electrical connections. Look for loose or corroded connections, damaged wires, or faulty components. Repair or replace any problematic electrical parts.
7. Engine performance issues: If none of the above issues are present, it's possible that there could be internal engine problems causing the loss of power. In this case, it's recommended to consult a qualified motorcycle mechanic or Honda dealer for a more thorough diagnosis and inspection.

Remember to follow proper safety precautions and consult the service manual for your specific motorcycle model during the troubleshooting process. If you're not confident in diagnosing or fixing the issue yourself, it's best to seek professional assistance to ensure a proper and accurate resolution.

Here is a basic wiring diagram for the CDI power circuit on a 2018 Honda Grom:

1. The CDI power wire is typically a red wire that runs from the ignition switch to the CDI unit.
2. The ignition switch is usually located on the right side of the handlebar and has three wires connected to it: a red wire, a black wire, and a white wire.
3. The red wire from the ignition switch connects to the red wire on the CDI unit.
4. The black wire from the ignition switch is typically a ground wire that connects to the frame of the motorcycle.
5. The white wire from the ignition switch is usually a power wire that supplies power to the headlight and other accessories.
6. The CDI unit converts the power from the ignition switch into a high-voltage spark that ignites the fuel in the engine.

Note: This is a general wiring diagram and the wire colors and connections may vary depending on the specific model and year of the Honda Grom. It is important to refer to the owner's manual or a detailed wiring diagram specific to your motorcycle for accurate information. Additionally, modifying the electrical system of your motorcycle may void the warranty and could cause damage or injury if done improperly

The hose on the bottom of the carburetor of a 2007 Honda CRF 100 should be connected to the carburetor overflow drain tube. The overflow drain tube is a small tube located on the bottom of the carburetor bowl. It is designed to allow excess fuel to drain from the bowl and prevent flooding of the carburetor. To connect the hose to the overflow drain tube, first locate the tube on the bottom of the carburetor bowl. Next, slide the end of the hose onto the tube and secure it with a hose clamp if necessary. It is important to make sure the hose is securely attached to the drain tube to prevent fuel leakage.

It sounds like the issue with your Honda XLR125 (1998) not picking up speed in top gear could be related to a clutch problem. If the clutch is slipping, it could be causing the engine to rev high and prevent the bike from reaching higher speeds. Clutch slipping is often a result of worn clutch plates, which can cause decreased friction and ineffective transfer of power from the engine to the transmission. Based on your description, it may be necessary to replace the clutch plates to resolve the issue. If you're unsure about the condition of the clutch, I would recommend having a professional mechanic inspect it to diagnose the problem and recommend the appropriate repairs. It's important to address any clutch issues as soon as possible to prevent further damage to the engine and transmissio

There are a number of issues that can cause a motorcycle to spit and sputter, including problems with the ignition system, the fuel system, or the engine itself. Since you have already replaced the coils, spark plugs, and wires, it is likely that the issue is not with the ignition system. Here are a few other things you can try to troubleshoot the problem:

1. Check the fuel system: Make sure the fuel filter is clean and that the fuel lines are not clogged or damaged. Also check the fuel pump and make sure it is functioning properly.
2. Check the engine: Look for any visible signs of damage or wear on the engine, such as leaks or broken parts. Also check the engine's compression and make sure it is within the specified range.
3. Check the exhaust system: Make sure the exhaust system is not clogged or damaged, as this can cause the engine to run poorly.

If you are unable to find the cause of the problem after checking these items, it may be necessary to consult a service manual or a professional mechanic for further troubleshooting.
