CB350 Tach

Hello all,

Long time reader, first time poster. I recently purchased a 1972 CB350 motor and frame, and am in the process of building it into hopefully something cool.

Besides the motor, half of the electrical, and some ebay purchases, I am pretty much starting from scratch. So, starting front to back, I am in need of all the gauges, controls, headlamp, bars, etc.

So that brings me to my first question, what is the drive ratio for the cb350 tach? I would like to go with an after market(smaller) set of gauges, and I would like to know which ones will work.

Thanks in advance for your help.
