Speedometer Ratio?

Post by DragonRider »



On an 1982 GL1100 aspencade what is the speedometer gear ratio? I have seen speedos with 1:1 2:1 and 2240:60 gear ratios but I dont know what the factory speedo is. Can anyone help me?

Alright so I used the Mostyn Industries webpage as a reference and ordered a 1:4 mechanical tachometer from Amazon. When I installed it, though, it showed about half of the true RPMs (around 500 at Idle). Did I get sent the wrong tachometer or is the Mostyn page in error?

I am wondering if, because the takeoff gear for the tach is on the camshaft, the Mostyn page is wrong and a different ratio is needed.
