I am a beginner to this sport and have purchased a 96 KLX 650. I think it is too much bike for me(not weight wise but speed wise). In first gear you have to be going about 10 to 15 miles per hour or you stall out. Does anyone know of any type of modification I can have done, short of buying a new bike, that would make this bike more manageable at low speeds? I need to slow this thing down. Help!
