It is definitelly the unique project
I appreciate all your comments. Bike runs great, tops at 40mph (65kph), has a lot of low end torque, carb just needs a little tweaking. I have ordered the performance CDI which should aid the difficult starting issue due to advanced base timing. I even think about arduino controlled ignition system.
The rear rim is holding up nicely, I inspect it for cracks after every ride.
I have attached the sprocket to the wheel hub which I cut off from the rim.
I will try to post more photos, just tell me what part interests you the most.
