Top speed calculator

Post by 72 »

Came across this a few days ago. Could prove useful for anyone thinking about playing around with different sprocket sizes or different engines. Sure beats doing the calculations longhand.

I use 3.25 for wheel diameter. Keep in mind the rpm is PTO rpm so you need to cut it in half due to the gear reduction (1.93:1 I think). If you have a stock kitty engine, enter 3000rpm. Stock driven (axle) is 42 teeth, stock clutch is 11 teeth all this equates to 8mph. Hope this saves someone some time.
