actually, (14mpg * 1.5 = 21mpg) 50% increase in gas miliage, only ($3-3.50 est) 15-20% increase in cost... size of tank a complete nonfactor (more gas, less fills, you pay per mile used afterall) so yea, 30-35% less in cost per mile fuel, and $37 less every 6 month insurance bill, and no $470 plastic hose connector dripping away ruining $45 ignition coils... added bonus, I can plow snow (truck will be comming with one) and put the motorcycle in the back with a small $150 invesment in a ramp, 4x4 for snow, and 420 ft-lbs torque to push commuters who are too busy doing thier hair while posting on facebook out of the way in the fast lane as they choke on black coal fumes of power.
math works great around the board!
