    Hello, I'm looking into dime city's 2.5" tachometers, the question is they offer two ratio settings, a 1.5ratio and a 1.7 ratio. Can anyone tell me what ratio would work with my 81 xs400 special II Yamaha?

    Thanks.

    The first result when inputting "tach ratio" with quotes into the search box to the top right will have you answer.
