16T front sprocket. you will need a speedo healer if you do it to keep speedo accurate. the gen 1 FZ1 sprocket is the one you will need.
How is that? all the info comes from the same place so if the speedo is correct the odometer is correct also. It just compensates for the gearing change. Not correcting the speedo will make the odometer inaccurate.
So if you set it up with the exact same amount of Speedo inaccuracy as the manufacturer put into it all will be the same. The problem is I guess that people never figure out how inaccurate there speedo is before they correct it.? I have checked my odometer against other bikes after the change and it has been correct.I have found that to be incorrect. In my experience, bikes are designed with a speedo variance intentionally. The manufacturer purposely makes it optimistic but the odometer is accurate. This is my experience with the bikes I've tested and what I've read online. My VFR, 919, FZ1, SV650 and my FZ600 have all been 8-10% off with the speedo and within 1% for mileage, verified with both GPS and mile markers. Several people here have found the same thing as well.
The speedo healer does not adjust the speedometer and odometer separately it adjust the signal being sent to the computer by adjusting the voltage so the computer thinks the gear ratio was never changed, it is just a simple math thing. Both the odometer and the speedometer use the same input signal so there would be no change in the correlation between the two.I guess it gets to be a little tricky when you set it up. I've never used a SpeedoHealer or anything like that but I suppose if you maintained the stock 'ratio' (for lack of a better word) between the factory speedo & odometer settings, you'd be a-ok
If you corrected your speedo 10% to match actual speed/GPS readings, your odometer would read that percentage too low. It's just something to keep in mind when adjusting that stuff. My 919 was 11% optimistic with speed but almost exactly correct with mileage. If I adjusted the speedometer 11%, I'd be reading mileage 11% too low for example.
Feel free to correct if I'm wrong :angel:
