80cc motorized tricycle

Saw this but no one showed how they did it so this how I did mine. 80cc motor I mocked the V frame by welding what would be the front of V frame to angle iron then U bolted it to frame so I can mount motor. If you mount the rear of motor angled to high the chain will rub on the bottom of the sprocket housing at the motor. I bolted the sprocket to the belt brake drum (rear brake still work) to alignment & hold sprocket stable. I used a grinder to grind away and expose bare metal where the sprocket meets the hub and did I my best to weld it. Since the tricycle is not exactly V frame I cut the exhaust and welded a tube to extend it so it can clear the pedals. Last I used an old tube garden hose hanger cut it in half drilled matching holes for the gas tank and used hose clamps to secure the tank to the frame wired the motor to complete the install and it works fine if my welds don't hold plan B is to get sprocket adapter to attach the sprocket to the hub.
