I have a two wheeler i.e. bike (Honda company, four stroke) which has four gear. While driving my bike, when I come to downhill slopes, I shift the motorcycle to neutral to save the fuel. (The slopes are not very long, so I cant turn off engine because I have no starter to quickly start it :) ).
But one of my friends suggested not to use neutral, but only hold the clutch while the bike is in gear. So I want to ask, what saves the fuel more between these two cases, shifting to neutral, or just holding the clutch? Or are both of these useless?
