To add to Pauls post, I also have a 700. I use SeaFoam ALL THE TIME. I usually put in one ounce per gallon. SeaFoam has an octane rating so you can use as much as you want per tank. I would suggest to use 2 ounces per gallon fo a couple tanks. Then drop it to 1 ounce per gallon of fuel. Also gas mileage is a little lower on My Hawk because of the ethonal used in gas now. That might make a slight difference in mileage. I usually get 150 to 175 miles per tank. Now it is slightly lower, But not much. As far as the dashboard issues, You might have a wiring issue. Other than that I don't know what it could be. Good Luck

You can find SeaFoam at most auto parts stores. (Expect to pay around $8 - $9 a can.) Give that a good shot and see if that doesn't make a difference.

The speedometer works fine and the lights but the others remain out. Occasionally they will fire up for a few minutes at a restart but rarely stay on long. I have checked fuses (in the center of the handle bars) and they are fine. It seems to me that the clutch pedal has something to do with it. I have seen something that speaks of the silicon recitifier as a possibility. Also, I consistently get about 25 mpg in town and around 40 mpg on highway only. It seems that it a good 25-50 % on the low side. Do I need to take apart the carberator for a good cleaning? Tire pressure is correct and idle speed has been adjusted, however the Nighthawk actually gets less gas perfomance that my Hyundai Sonata car.
