Hello guys, i have a 73 TX500, i'm looking to change both my tach and speedo to a smaller mini gauge set up. My question is what raio speedo do i need to use. 1:1 OR 2:1 or maybe something different? also will any aftermarket tach be the same as long as the cable fits? Or is there a certain ratio i need to use? Thanks for any advice you have.

Got a new toy the other day and i need some help with a few things but i will start with this question. Which coil goes to which cylinder? The coils are mounted under the fuel tank and they are one on top of the other. Thanks for any help.
