Output shaft help

[Kieran]

Does anyone know the size (diameter) of the output shaft on a blaster, im trying to find sprockets for my bike and hoping i can use a blaster one, just stuck on the size.

Thanks

I have a brand new sprocket here and the demention inside the inner teeth is 15.22 and the larger part of the inner teeth is 19.81 hope this helps. i hope you understand what i'm talkin about. the gear like teeth on the inside of the sprocket that lock it in place on the shaft are the measurements i gave you

on the same topic, its a 250 4 stroke, that had origionally a 12tooth, what difference would giving it a 14tooth make? giving that its a different design of engine

 

[scotj77]

gear ratios are gear ratios no matter what they are strapped to. more top end & less bottom end with a 14 instead of a 12

thanks i wasnt too sure since its a 4 stroke, as most talk on here concerns 2 strokes.
