What is the best size sprocket to go with.Im putting a 440 kit with a stage 2 hotcam.I ride mainly on trails,but love to race around.I was looking at the 16 tooth.Would i lose all bottom end with this?Also should i use a performance cdi?I was thinking of using a AMR stage 2 cdi,but dont know too much about them.Please help!!

 

more teeth slower acceleration, about 15, less teeth better acceleration, about 13,

 

So,a 13 would be best?How does that do on topend?I know the cdi goes up on the rev limit,but what else does this do?

 

i put a 15 on mine and it was a shitty launch, but a great topend, 13 or 14 is best on both in my oppeninon
