Hi, Do you think you will need to modifie your KLX250 to suit your need for better power? I just bought one myself, but haven´t had a chance to ride it yet. I did take it for a ride around my mother´s lawn, but didn´t have enough room to get out of second gear. I thought that 1st gear would have been lower. I´m also being careful not to go over 4000rpm´s until I´m suposed to. David
