I'm going to start with adding one of the fuel controllers first. I figure this bike was programmed and tuned in optimum settings, humidity, temperature, elevation/pressure. This is probably one of the reasons for some of the varied performance reports. If money is no factor at ALL, what would be the highest recommended fuel controller. I am pc literate (associates) and just previously worked 3 years as a auto mechanic.... not motorcycle.... but an 02 sensor is an 02 sensor. What would you folks recommend? and why? other than cost.
