Greetings everyone.
I recently bought a 1997 Road King off a friend who passed away before I could get more details about the bike.
I seem to have 2 minor issues that I hope someone with experience and tech background could help me with.

1) Fuel Gauge - totally off, reaches E when tank is still half full.
2) Speedo reading is off (Shows 60km/h when actual speed is 100km/h)
Some say because the bike has 18 inch rims (original were 16 inch) now that's causing difference in reading,
others say it's because the bike has a Jim's 6 speed on and that it has a separate module to calibrate the speedo.

Greatly appreciate any info you guys may have.

Regards from Malaysia!

 

1. More than likely you need to clean the varistor in the tank. Scotch Brite works for this.

2. Yea, I'd bet it's the 6sp transfer causing the ratio difference to the speedo. There's various calibrators out there for about a hundo.

 

Are you sure you don't have an American Speedo. The number you are saying are close to what an american speedo would read at 100km/H

 

Yes, mine's in km/h.. probably cos export model.

 

Look at odometer.
Measure a distance ridden.
GPS is good for this.
Confirm that unit is not measuring in MPH.
There have been times that folks changed backing on speedometer in order to export but unit calibration was unchanged.
Basically, confirm that needle matches the odometer (distance traveled).
If not then a calibrator will be required that works with a 6 speed.
Dakota Digital might be such a unit.

 

Will look into this asap.
thanks buddy.

 

So i did a lil researching and found that there's a re calibration module that can sort my problem out however would appreciate if any of you guys can confirm this?
See oic attached. (I've emailed them but still awaiting response)

 

That's the one I was thinking of. Never used one though, but they do what they say they do.

 

" More than likely you need to clean the varistor in the tank. Scotch Brite works for this" True ALSO check any connectors in the fuel gage circuit for corrosion.
