What is interesting about this project is that because it is a shaft drive reducing engine rpm by changing final drive ratio is not practical or easy. Therefore if I can get 2.7L/100km [87mpg] in the Vegas/Barstow challenge with a 500cc V-twin, it will be quite an achievement and will show that if the rpm of the engine could be reduced [from 5000rpm at 70mph to 3000rpm at 70mph] then over 100mpg is within the range of a 500cc bike.
Changing main jets on this bike is a pain because the carbs are 'wedged' into a small space and must be partialy removed from the engine to gain access to the float bowl.
