OK, I finally have the kids SSR/Z 50 bike done. I just put in a 88 kit from TB and a 18mm Mikuni carb. It has quite a bit more juice now but, it seems to continue reving a bit after letting off the throttle. It seems like the slide is closing right away but it still revs a bit before spinning down?? What should I look at? It is also a pain to kick over now, but runs A1 once fired up. Is that right?
