Couldn't get a response anywhere else, and I figure there are some knowledgeable people here that can help me. My dad recently purchased a 2006 honda Nighthawk 250, and while it is fun to ride, the acceleration is not enough to make me hold on tight. I was thinking that I could up the jetting, possibly get a bigger carb, and maybe go down 2 teeth on the back sprocket. Is there anything else I can do to it , such as taking some sort of restricter off the carb? I know they come lean to meet EPA emissions. If i were to do the above mentioned, what kind of increase in acceleratin would I notice?
