Gears and compression are the road to efficiency, for sure.
When stock with low factory compression my 1000cc GSPD got anywhere from 13-16km/liter. With 1050cc pistons, modded '77 S heads running higher compression (12:1 estimated and making much more
power and torque) it netted 20km/liter pretty consistently.
Don't know how it'd run on Nepal's gas, though.
I've been riding airheads since '83 and know them fairly well. If I left today for a round the world adventure... I'd take my KLR.
