Hyosung GT250R Tacho not working

Hi, I adjusted my clutch on my Hyosung which now is working perfectly, i then fueled my bike and seemed to run ok. A week later i went out and rode it and the bike dramatically loses power up the slightest of inclines. I thought it may be dirty fuel so drained all bar a couple of litres and went and fueled up with premium. I have ridden round for an hour and it is a little better but the bike still loses power on inclines. Can anyone help me or advise what i can do to fix this issue?? Cheers

These bikes are never senen with many miles on them when for sale, invariably they have issues uncommon to a newer bike, this sis due to the workmanship and metalurgical issues etc, they are clones but thats where the similaritys end, they nevr last from all I ever saw of these bikes.
If you mean loses power on hills due to clutch slippage, the springs i know get weak fast and lose tension sufficient to engage fully thus allowing plates to slip and losing power to the rear wheel, if you mean otherwise nobody can tell you this way correctly.

SOURCE: Oil type

there usually is not a break in period anymore but when you get your first oil change refer to your owners manual. you did not say where you live but a 10w30 5w30 is recommended most. Always use a Multi viscosity oil like 10w30 the 10 is the viscosity at start up so your engine starts better. The 30 is the viscosity at operating temp. the w means that you can use it in winter. The API that you see on the oil can means American petroleum institute. SAE on the can means society of automotive engineers Viscosity means flow rate and you need to keep oil flowing at all times

SOURCE: Gearbox oil change

There should be a drain plug either on the bottom of the gearbox or on the side of the gearbox at the bottom. Put in fresh 10w40 motor oil. There will be an oil fill screw either on the left or right side of the gearbox case.

SOURCE: 2008 hyosung wont start

I am assuming you mean with the starter button.

If thats the case check that you have power to the button, and if so powewr coming out of the button.

If all is good this far, check the starter solenoid and starter for operation.

try taking 12v directly to the starter and see what happens..if it turns then the problem is before the starter.

Hyosung GT250R 2006 Miss Firing In One Cylinder


If everything that you checked truly is 'running perfectly' than you wouldn't be having these issues. Compression doesn't change - either it is good or it isn't. ignition either works or it doesn't most of the time - with the exception of it running til it gets hot then quits until it cools off. so that leave us with carbs. Obviously one of them isn't delivering fuel consistently or evenly or maybe your not giving them fuel all the time(water in the gas?). If you separated the carbs they are more than likely not 'sync'd anymore. That means that one is opening faster or later than the other so one cylinder is getting to do more work. Your best bet is to take it in and have it serviced so that the carbs can be checked over and re tuned so they are opening correctly.

Hi, Ron and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a "LOAD" test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.

2008 Hyosung GT250R will not turn over


Hi, Mcle_cool before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.
