Speedo convert, wire -> sensor
I have converterd my wire speedo to a sensor type and having calibration problems.
I have changed to this speedo with rpm indicator.
The bike is a chopper build with -99 evo and -05 5 speed ultima gear box. I down now about gear ratio, probobly not original.
I have tested the speedo and the problem i have is that is not showing near by actual speed. If i do 80kmh the speedo shows 50kmh.
I know there are some calibration tools but i think the fault is to big. S&S calibrator can fix up to 69% wrong and now this is 60%.
And also one thing is that 50mph is near 80kmh. Is this just random ?!
Anyone else tested this speedo with the same issue ? Should i just buy the calibrator and calibrate or could there be any other problem ?
