Like I said I have only rode for maybe two hours on it but in that time I went through all ten of the settings. Two of them are stock and two are reserved but out the choices given I have mine set on number 5. I mostly ride on tight trails in the woods so with that setting the power hits a lot sooner then stock setting. I'm impressed with the results but I know I will hang on to my stock cdi unit just in case something would happen to the rm stator even with the one year warranty theres no point in not being able to ride for a few weeks if you have to send it back for a replacement.
