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: Air Filter GT250r
hold it up to the sun and look thru it if you can see thru it just blow it out and run it until your next service and check it again
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: my 2008 hyosung gt250r doesnt start, all light and
does it crank over?....if so check spark...fuel...etc...try to narrow it down to a actual problem such as carbs clogged, or injector not working, other than wont start, not able to tell much from that.
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.
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c
