Question Lift Front End of Motorcycle - Good or Bad for MPG?!

Hey guys, so I HAVE to lift the front end of my motorcycle via some 2" fork extenders. This is to have slightly more ground clearance on the front skid plate, and to 'relax' the riding position a bit since I do very large distances.

Do you think I am going to get better 'aero' and actually bump up my MPG's?

My thoughts are that my whole body will become more of a teardrop shape by tilting i back about 1/2", and so the 2" lift of the front will actually help the rear profile of my bike (with me on it of course).

The way you sit will probably be the answer. I'd need pics to give a better guess.

I would think it would increase your drag by raising the front. Lowering the front would give an improvement I would expect.

Not sure you would notice any significant improvement or penalty either way unless the change was really significant.

Net lift or downforce or side force are all bad for drag.

A relaxed position could help you lower your speed => that's your best bet for FE gains I am affraid ...

Could also reduce the drag of the fins if it is an air cooled engine ...
