Hi to you' all !! The name and location: Victor from Fort Lauderdale. I done two kits so far, a 70 cc first and a 48 cc, both chinese happy times types. The 70 cc is installed on a old japanese frame with 700 mm tires, bianchi hubs, alex rims (everything salvaged from discarded bikes). Runs excellent after 8 tanks of gas & it takes me to work everyay (everyday it doesn't rain, that is!!). Now the 48...putted together for my brother...starts great but it develops a screeching noise on decceleration and it vibrates a LOT on acceleration at midrange. I will search for solutions in the applicable threads!! Well, i'm sure it will be a pleasure to be part of this community.
