Plates on my chain?

[Venom]

Hi all,
I need to know how many plates are on my chain. I dropping one tooth on the top sprocket and the store I called to get that sprocket asked me "how many plates wide is my chain".

Cheers.

im pretty sure vipers are a 3/4" hyvo, not sure how many plates though. you need a spacer if its not a direct yamaha replacement, like a polaris gear.
