Sounds like the clutch throwout bearing. This bearing sits against the inside of the clutch basket outer and works against the springs when you operate the clutch. If the noise goes away when you pull the clutch, it is usually the throwout bearing. Also check the main clutch bearing, as a loose one will cause chatter and will also wear the throwout bearing.

The digital speedo works off of a couple sensors that I would have to do research to find. To begin with start by testing with a mutil meter at the plug at the speedo to see if you are getting power. That would elimate all sensors, then if you are not getting power you would know it is electrical and not a sensor. If you get power then It would indicate that a sensor is gone out, most likely the speed sensor. If you dont have power you will need to first check the fuse that controls that circuit, if it is good then all you can do is follow the wires to the problem by checking the OHMs from one section to the next until you find the breakdown.

I'm new and I see peeps changing their tires on this forum around 5000 miles or so . Maybe a stupid question but how do you tell? Obviously if you don't ride much and have some dry rot goin' on would be definitely a good time to change. Is there a typical measurement of tread showing that will tell me when it's time to change?Hey Dave. If you look at your tires between the treads there are little raised tread wear indicators. When the tread wears down far enough to make those indicators touch the road it is about time. The exception this is the Metzler Z6, the tread wear indicators are really tough to find on those. You will find that mileage will vary greatly. I seem to get about 3000 miles out of Sport tires and was only getting abut 4000 or so out of sport touring tires. Some guys here seem to get double that or more. I think that mileage will be dictated by terrain you ride, the pavement type (very course here) and your right hand.,,,

Sounds like there is too much of a load on that circuit. You need to do a battery/charging/draw test first and foremost. You can normally have these tests performed for free at your local auto parts store. It could be a bad starter pulling too many amps for that circuit,or it could just be that the valves need adjusting. But get the battery/charging/draw test done first,and that should point you in the right direction.If the tests come back in spec,..then i would start looking for a bad ground,or a pinched wire.Especially around and on the handlebar controls.

Get another person 1 hold the key like their trying to start it while the other TAPS not hit the starter with a hammer idk what kimd of car so I cant really tell u where the starter is located.

Hi Im not 100% certain what the hyosung diaphram looks like, but most are held in with 4 small screws holding the plate where the vac line goes. There will be a spring and plunger activated off the centre of the diaphram. This should come with the new diaphram.
You will need to remove the fuel tap first, or have the tank upside down on something soft.
You are only dealing with a few screws and a couple of parts, so just go slow and remember how it came apart.

a thin smear of rubber grease my help fit the new diaphram, do not use silicon, it can stop the diaphram moving and is not petrol proof

Question edited for clarity, typos, add CAPS. Did the take the connectors away? Otherwise, use bullet crimp connectors and shrink wrap sleeve same colour to same colour. https://www.google.com/search?q=2011+hyosung+gv250+efi+wiring+diagram ..

Check the actual switch on the handle bar. These can sometimes fail and stick in the on or off position. This could also be a faulty solenoid between the battery and the starter motor. Try this. Find the Solenoid. It's usually a small, black, round barrel shaped block. It will have two small and two large cables attached to the top of it. Disconnect one of the Small wires and reconnect the battery. If it kicks over it is most likely the solenoid. Disconnect the battery. Refit the Small wire then reconnect the battery. If the engine kicks over it could be the actual starter button.

Question edited for clarity and toss in some CAPS. Charge the battery up whilst it is still in the bike. If the voltage is lower than 11 volts or so with the engine being drained by the starter, there is not enough power to operate the fuel injection. The battery needs to be 12.4 to 13.2 volts. https://www.google.com/search?q=2018+Hyosung+GT125R+crank+won%27t+start ..

That was not the drain plug you pulled. Here is where i learned alot about my bike great source for information. And dyi guides. Idk when this was posted but you want to go here before you get into alot more of a project. https://hyoriders.club/forums/topic/wrong-drain-plug-for-oil-change/

There could be several possible causes for your 2002 Hyosung GV250 bogging down when starting out. Here are a few things to check:

1. Fuel system: Ensure that the fuel system is functioning properly. Check for clogged fuel lines, dirty fuel filter, or inadequate fuel supply.
2. Carburetor: The carburetor may be dirty or clogged, causing a lean fuel mixture. Clean the carburetor or have it professionally cleaned if needed.
3. Air filter: A dirty or clogged air filter can restrict airflow to the engine, leading to poor performance. Check and clean or replace the air filter as necessary.
4. Spark plugs: Worn or fouled spark plugs can cause poor ignition, resulting in engine bogging. Check and replace the spark plugs if necessary.
5. Exhaust system: A partially blocked or restrictive exhaust system can cause poor performance. Check for any obstructions and clear them if necessary.
6. Electrical system: Ensure that the battery and charging system are functioning properly. Weak battery or faulty charging system can lead to inconsistent power delivery.

If these steps do not resolve the issue, it may be necessary to have a professional mechanic inspect the motorcycle to diagnose the exact cause of the problem.

No one has experienced your issue although there are some electrical issues in the link. Check the all the connectors around the cluster. Break the connections, spray with switch cleaner and remake the connections. https://www.google.com/search?q=2013+Hyosung+GT250R+cluster+not+working ..

i know this may seem drastic but in my experience i have found that the Chinese electric connectors are normally at fault first thing i would do is chop the connection block out and either put your own bullet connectors in or solder the wires together either way it is the connector at fault and needs replacing

The fuel gauge is faulty and should have to be replaced.

It sounds like there may be an electrical issue with your motorcycle. Here are a few things you can try:

1. Check the battery connections - Make sure the battery cables are securely attached to the battery terminals and that the connections are clean and free from corrosion.
2. Test the battery - Use a multimeter to test the battery voltage. A fully charged battery should read around 12.6 volts. If the battery voltage is low, try charging the battery or replacing it.
3. Check the fuses - Check all the fuses in the fuse box, including the main fuse. If any of the fuses are blown, replace them.
4. Check the wiring - Inspect the wiring for any damage, loose connections, or corrosion. If you find any issues, repair or replace the affected wiring.

If none of these steps help, you may need to take your motorcycle to a professional mechanic or dealership for further diagnosis and repair.
