2008 Hyosung GV250
I enjoyed owning this bike
When buying it, the dealer said to leave the petcock "ON" at all times, which led to most of my problems.
When parked, the front cylinder would sometimes fill with fuel and hydro-lock; not enough air space for the piston to go up and the engine would not turn. This caused a broken starter gear, and later a broken keyway, which caused the engine to lock up. I learned through experimentation that if you take out the front spark plug (easy access and the tool is included with the bike) and bump the starter, any fuel in the front cylinder will shoot out the spark plug hole and go about 20 feet, then replace the spark plug and it would start easily and run great again.
At about that time the dealer got a service bulletin which said that the petcock had to be turned off any time it was being parked. After I got in the habit of doing that, I never had any more problems like that.
The bike had a vacuum driven fuel pump, and when the throttle is wide open it generates very little vacuum. Sometimes in climbing a long hill at 65 mph or more when the throttle was mostly open, the engine would start to hesitate because it was starved for fuel. Once you reached the top of the hill and could close the throttle a bit, it evened out and had full power again.
Good acceleration and could keep up with bigger bikes except on the interstate; it could hold 75 mph on level ground, but not always on hills.
Good looking bike! People would stop me on the street to compliment the looks of it. That no longer happens on my current bike.
The seat was uncomfortable on long rides.
Lightweight, low, easy to handle.
Hard to get parts and accessories. A few US places are starting to carry them, and some places in Korea were offering decent shipping rates.
Would you buy another motorcycle from this manufacturer? Yes
