Exclamation Team Motorcycle battle plan

Congratulation team, we are number 1 with 68,52 MPG

That is 5 MPG more than our second in competition : team diesel.

We are also 15% above EPA wich is good but not as impressive as the third in competition : team Metro @ 42% or team Honda @ 52%.

So we picked the good vehicles (light and efficient at least on a power per litre point of view) with plenty to gain on an aero point of view and easy hypermilling techniques : resist the urge to let 'em sing !

But let's be honest, on a MPG vs vehicle weight ratio or MPG vs potential number of people on board, we suck !

So if you guys are up for a friendly competition spirit, let's discuss the topic with a team point of view.

My first analysis is we lack our champion in the team, Euromodder for example.

Second item to think about is engines.
Motorbike engines are too powerful hence wasting gas.
Why is that so is because they have high power per litre ratio and narrow power band and the need to have narrow gear ratios, the lack of ratio being made up for with the high rpm potential.
What about shorter cams with high compression ratio ?
Can it do for a harsh ride with rear wheel lock when downshifting or whatever else ?
The target would be to make them pull the same torque at a lower RMP.

How can this be done ?
