Reply To: 2007 hyosung gv250 slow acceleration.
2002 yamaha yz250f, I understand the weight difference but still the hyosung in so slow
The same GV250 engine used in New Zealand GTR bikes for Hyosung racing they can push 95mph when tuned right.
The torque can be forgiven due to Yamaha being lighter in fairness but really all depends how well the GV250 was looked after ? And if the engine needs an overhaul if its been too old of neglect
1 tooth down on the front sprocket helps but you lose about 10mph of whatever top speed it has on now. Id focus on the engine health first 🙂
