Yes , there is a charging circuit , yes there are performance CDI's , coils , etc. , personally I don't think you get any benefit from those unless you're going with a big bore kit , or performance head , cam , exh. , etc. Slugs'? No , not if they're running right and the CVT is working right . They do the job , remember they're just 150cc . There are lots of suspension , chassis mods. to be had . You found the right forum , See Ya .
