I am wondering if there any aftermarket parts that would give my Vinson better throttle response any advice would be good to hear!!!  

check to see if there is a profire coil offered,
and maybe a hotter cdi box.

you can rejet the carb, but iam not sure it will actually have the desired effect on a four stroke without boring the engine or reworking the valves.

so it would be simpler if they offered a hotter coil or cdi box, to buy those and plug it up.

also you could put a uni or k&n filter on it to help it breathe a bit better. I actually prefer the Uni filter over the K&n.  

Are you still looking for more power and throttle response? Have you modified it any so far?  

Well to give you an up date I did put a profire on and it seems to have made a diff. but not all that I want, I already had a K&N and  HMF pipe but now from what I hear I would really like to find a CDI but no luck so far!! I appreciate your replies and would like to hear any more you might have for a CDI.  

did u tune it after u put on the pipe and filter?
