So I have a 1980 Cb750c, it had comstars on it, and Im changing the wheels to the wheels from a 1981 CB750K 19" Front 17" Rear. My questions is, do I need to get a new speedometer drive unit from the K model, or will the one on my custom be fine? And lastly what's the speedometer ratio i'm looking for? some people said 1:7, others said 2240:60
