I have a 10:60 gearing right now, the Polini 80cc kit, stubby MLM Proma style pipe, VM20 carb, B8HS spark. Stock points ignition and timing. Stock clutch and springs. Previous owner made all the motor mods for the exception of the pipe.
Went around the block topping out 20mph with temps in 360s and climbing, motor over revving, crazy vibration. Maybe 10:60 gearing was okay for the stock 49cc setup. I need to re gear for the Polini and can get pretty much any size rear sprocket from 27 to 72. What would be a middle of the road gearing setup for acceptable acceleration and top speed? The V1 gearing chart floating around here won't apply to the Tri-Ped.
