At that mileage (77K ?) many things are possible. I would not rule out simple wear and tear. A complete holistic approach to determine condition and state of tune should come first. High mileage introduces too many variables. Eliminate them first. Replace plugs, air filter, clean and sync carbs. Now, how does it run ? Fuels with a high dye content eventually restrict jet openings, Wear in the slide bores will cause a strange behavior since there is air leaking around them. A leak-down will show any imbalance in cylinders. How much ethanol is common in your part of the country ?

I'm wondering how old your bike has to be before it has these problems. Is the 91-03 Nighthawk 750 affected? I've noticed a greater difficulty starting lately and a surging at low RPM which clears up at normal speeds. My bike now has 77M miles on it and I'm wondering if years of 10% ethanol gas may be causing deterioration inside the carbs. Jay S 92 NH750 South Florida A Good Credit Score is 700 or Above.
