Adding teeth to the front sprocket will increase top end speed but reduce the power of the bottom end.

Every one tooth you add or remove from the front sprocket is equivalent to 3 teeth being added or removed in the rear. Sprocket chart below

A fuel tuner is always recommended when installing a full exaust system. You have now eliminated excessive exhaust resriction which the OEM ECU has been tuned to run with. By including the fuel tuner you will not only increase the HP and power of the bike, but you will also be helping the bike to run smoother, eliminating and flameout issues and cutting down on decel pop.

Dyno and field tested, the Power Surge 6X will allow correction for humidity, temperature, air pressure, along with race fuels and motor modifications. The tuner adjusts in a matter of seconds in 6 zones, including an accelerator pump feature for more throttle snap response. The tuner can add or subtract fuel from the injection system. Conditions like rich or lean running, and stalling from flame-out at low revs can be corrected
