Clutch & Bike fuel efficiency?

arush_in questioned:

I am so fuel efficiency concious.I subdue now strongly belive that disengaging the engine increases the fuel efficiency. Therefore even when I anticipate a small slope in the road,I accelerate the engine a bit more before the slope & then take in the total of the slope with my clutch engaged.That is without using the engine at all.This not only disengages the engine but riding with the clutch is more safer and less requirement to apply brakes,therefore no wear and tear of potential owing to brakes.Recently a name told im doing a mistake.Can any one give a real in rank on this delight?.Im looking only for honest forwards answers for my privileged than Qn, as I know very well that applying clutch and unreliable gears and accelerating with the clutch and applying brakes at the same time are all most terrible driving practices.My Qn is unadorned, Will transmittable the clutch and disengaging the engine at slopes boost the fuel efficiency or not?if no why?Also in view of the fact that the vehicle is tender closer in slopes with clutch,why engine?
