I read this evening that if I’m running a 19 tooth driven gear and my speedometer is reading 50 and gps says 55 mph that I should add a gear with MORE teeth. I ordered a 22 tooth driven gear and hopefully this will get mine real close... 3 more teeth will get me 5-6mph.

Does this sound right?

The guy at the auto parts store said the same thing.

Thanks for all the replies.

Greg

I’ll post my findings when I know for sure.
