if you just put on a good cdi you increase mph.
just up jetting is questionable with a cylinder kit and pipe..you need a new carb17-19mm
never go by anybodys recommendations for up jetting
you probably live in different conditions than they do and elevation is critical too.
hot/cold have different air conditions hot is thinner cold is denser and may have more moisture.
you may have to re tune for summer or winter if you ride year round.
