Speedometer and tachometer ratios

[rappz7]

Hey there everybody. I'm looking to put a smaller tach and speedo on my bike, thing is im not sure what the ratios are. Can anybody out there help to shine some light on the subject? Thanks. Also, I am aware that I could have searched for this information and it "might" have helped but as some of you might know its kind of a pain in the a$$.

Thanks again and all input is appreciated.

I like them a lot, the speedo has idiot lights built in. I see its out of stock there though. They have cool trim rings for them now too, going to have to get me some of them.

Edit: they have black faced ones w/ lights in stock.
