Hi guys I have a question for yous I have a 79 sprocket an a 13 clutch also a 66 sprocket an a 13 clutch which one will I hit the 13k first an what can I use to hit about 90mph. Thank You Larry.
79T will hit 13k quicker. 66T will yield a higher top speed.
There is a formula which I am the last person to ask ask about it! But with a 16/70 my friend figured it was 95mph.
Larry, it took me all of 5 seconds to look this up on the internet, maybe you could do a search and figure these things out yourself.
Anyway, here is how to calculate gearing and speed.
