It's a good thing the Royal Enfield's don't have a knock sensor.All of the normal "ticks" and "tacks" and "clicks" and "clacks" would drive it out of its mind. Thanks for the help!
..still a bit more backfire than expected since i put the EFI pipe on. Should i have to change the FI mapping? or spark plug? anything?
So with the small tank of the enfield you may find me lurking at gas stations and then running up to the pump that the new BMW's and such pull away from!
I agree for the most part now a days. Only in cars with fully computer managed engines have I seen in increase in fuel economy with premium in the tank. Example my moms car with the north star V-8. The ECU controls both the ignition and EFI. It continuously adjusts mixture, advances timing and adjust timing curve to optimal settings based on the feed back from at least a shoe box full of sensors. Each cylinder has it its own knock sensor I do believe and there are at least two O2 sensors on board.
What size is your tank? I put 11 litres of petrol in mine yesterday and it had only just gone on reserve.
