Been Around the Block
The instruments are a headache, as want to use OE looking set, but they are mechanically driven, which can't do anymore on my bike. I can buy an OE electronic tacho but no one seems to make a matching speedo. More thought required.
Drive the speedo off the front countershaft sprocket via a VFR750/RC36 drive mechanism. Quite a few Zrx1100/1200 owners do it when swapping out to a Zx/Zzr14 front end. There’s a kit on Webike for the older Kaws. I’m making my own setup for my ‘78 that I’m swapping Ducati GT1000 spoked wheels onto. I ordered a speedo cable from Germany for a CB1000 or CBR1000F. I think the length is 1040mm or something like that.
Just a thought….
