Thank you.
Need chain and sprocket advice please.

1. Is chain size 428 strong enough? Because I found all the components in this size.
2. What do you think about an 1:6 fixed gear ratio, on 19 inch tires, centrifugal clutch, 9 HP engine. The clutch already has 1:2 reduction. Planning to get 12T small sprocket and 36T large sprocket. This gives the overall 1:6 ratio. There's the option to go larger/smaller on either sprocket.

The theoretical speed is 31 kmh when clutch becomes locked @2100 RPM
55 kmh @3600 max engine RPM
