speedometer woes.

Post by ZOSO »

With my recent regear my speedometer is now fast. By about 18%. So doing the math I's need a 24 tooth driven gear. Well they only make a 21 max. Current is 20teeth. Not sure what the drive gear tooth count is. Any ideas on how to correct it with out buying a new digital cluster?

Replace the speedo drive gear on the output shaft with a 6 tooth version.
