maybe a small carb ajustment but thats it.i´m building one to look like a 1920´s bike the only thing i´m going to use is the motor and electic parts.i´m looking for a front wheel for the rim so both are the same.i´ll lace it to the back hub, spoke count should be the same.i also am making it foot clutch,hand shifter like some i had in the old days.a ridged frame springs under the seat longer frame in rear.a 1919 look with a newer motor.i´ll make a new tank to fit it.my first bike was a 36 indian.i miss it.
