8600 rpm with a 44t on the back would be 39.001 mph. To reach 50 mph with a 44t on the rear you would need to spin at 11025.2 rpm. With the 32t you need to spin at 8018.3 rpm to hit 50 mph. You are also now running a 13.12:1 reduction. That's a dog on takeoff with these small engines unless you bump up the power.
