I got the 66cc motor from zoombicycles yesterday and put it together. I was advised to remove the fenders, so I did. I did nothing special, just put the motor kit on the bike as it came in the mail. It started up within 4 or 5 tries and adjusted the carb, I have done nothing else to except ride it. Being the first one for me to finish, I am still excited. I like the cruiser bikes and the cranbrook was a natural (and cheap) one to go for. Now I guess I need to start the slow process of working out the bugs as I notice them.
