ok, so I got a speedometer and rpm gauge, I suspect they are both off. Speedo is off by like 50 mph and the rpm gauge is a 1:67 ratio and I read ours are 1:5 supposed to be. I’m trying to figure out how far off the rpm gauge actually is. I’m running the standard 16t front drive sprocket with stock 39 in back for my 78 xs400e.
Can anyone help me figure out what my rpms are supposed to be standard and what they would read on the one gauge that’s off? Let’s make an easy number of comparing 1000 rpms. So if I’m at 1000 rpms, what is my gauge going to read?
