Ok, I have a '92 Honda Nighthawk 250 that just came back into my possession after 8 years of sitting in someone's back yard. It runs/starts perfectly, and my only complaint is the top speed. I realize this bike has a very limited horsepower, but right now it tops out at about 70, and if the wind is blowing, 65. I would like to feel more comfortable getting on the interstate by getting a few more MPH and not have to keep her maxed out just to keep up with traffic. This bike was put through a lot, and I am not looking to make miracles or spend a lot of dough, but is there any suggestions for getting it to run around 80? OR was this thing just meant to be a trumped up moped from the beginning?
