Went from a decatted stock head pipe, slip ons, a SE air cleaner, and a PCV. To a fuel moto 2-1-2 headpipe and a powervision. Noticed after the install and its maiden voyage I have more vibes when letting off throttle and higher RPM applications. Would yall say this is a result of the new harmonics of the new headpipe or do you think there is a possibility my crank has slipped with just 3500 miles? Bike is rode hard I take care of it but when I ride I do ride it pretty aggressively.
