****************CROSS MULTIPLY AND DIVIDE-------------------------
Good racers pay attention in school it ashame school don't have many racer teachers.


9500 rpm is to 11.25 as

12000rpm is to X (what I want to know)

12000 x 11.25 = 135000

135000 divided by 9500 = 14.21 to one gear ratio needed to get to your desired rpm if the motor will do it. That should be like running in 1st gear.




The 14/51 gear is equal to 3.64 x 3.32 (ratio in second) = 12.08 to one

the 16/54 gear is equal to 3.38 x 3.32 (ratio second) = 11.22 to one

this would require 16/58 3.63 x 3.32 (ratio second) = 12.03 to one or

16/59 = 3.688 x 3.32 (ratio second) = 12.24 to one You pick probably need to talk about that front sprocket and fold over washer and impact wrench now. Check your gears again because this seems more like a 3rd gear ratio # that you are giving me.

Now would be a good time to go back and thank that math teacher for teaching you something you can use, It would have been a lot easier for you to do math if you could have seen the use for it in racing in the future.


If you could change the front sprocket to 15 teeth. 54 divided by 15 = 3.6 x 3.32(second gear ratio) equals 11.95 to 1.

PS. "Dant" when did "Big Daddy Roth" get a ride in a 270 sidewinder or is that ol "Rat Fink" in there?
