Gear / RMP ?

[Norton22]

Can someone help me out I am trying to determine how many RPMs I will go up by changing my gear and going up 21 points

Thanks for any help

Think I found something Dave posted 125RPM increase for every .1 I will go up so it would gain 262 RPMs is this correct

that should be close i have always had between 100 & 125 rpm per point
