I bought my wife a Wildfire R5, the owner of the shop showed me a neat way to modify if for a little more speed. There is a tube that goes into the air filter case, the end of that tub has a cap on it with 4 holes in it, I took that off and now it rides great, can even go faster then my Kmyco Agility50. Can some kind of airflow modification be done to the kmyco? I really hate to mess with the CDI.. Thanks, am new to the fourm, hope to hear from you all soon!
