Question about 2005 Hyosung GT 250

2007 Hyosung GT250R CHOKING at top end

As long as I am contantly accelerating and breaking, city traffic, the bike is responsive and bad ***.  Once on the highway in 5th gear it won'tlast about 1 to 2 minutes before it begins to choke little by little until I've come to a complete stop.  Where can I control the amount of air to gas ratio, i think it might be getting too much gas when the throttle is all the way or close to all the way down for a long period of time.  This bike was bought after it had been without use for a couple of months, maybe a year.  Ive used about 3 to 4 gas tanks worth since I got it early december.  The first time I rode it in november i took it for a long ride to a dealer to have it checked and it made the trip there and back without this problem.  What could have changed?

Hi ..... Lots of variables on this one. Pull the petrol pipe from the carb(s) and ensure you have a stong/steady stream of petrol. Remove the spark plugs and have a look at their colour, should be a light tan. The petrol tank has a breather hole near the petrol filler OR through the filler itself make sure this is clear and unabstructed.
Let me know how you get on.

-this is probably some kind of overflow for unspent fuel - or oil vapours - one line will lead in - the other is probably a drain or overflow - which usually drops excess fluids on the ground - without a picture its hard to tell

Hyosung GT250R Tacho not working

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.

I haven't started my bike in almost 1 year. The starter does not even turn engine. I replaced battery and lights work. No noise at all when I press starter.

i have a 2007 gt250r and had a similar problem, on the right side beside the battery between the fairing and the frame is the starter solenoid, you can test it with a test light by putting the clamp of the test light on one side then the light on the other side, hit the starter button if the light doesnt come on it is the solenoid, about $50 off ebay
