Hi all, I have a 1939 WM20 near complete (1939 frame and later motor), I have a speedo drive on the front axle but no speedo, when I look at E-bay there are a lot of aftermarket Smiths but have different modes or ratios. Can anyone inform me of what is needed in a speedo to match the drive and they also vary from 0-90 upto 0-240, knowing the bikes limited capabilities again which one is correct ?
I am in Australia but if anyone has what I need freight is no problem
Regards
Kevin
