hello, I just got into this recently and did all the homework on it. CA Laws, CARB, License and Insurance. But the item that is really frustrating is the poor quality one-way bearing. I don't have a welder so I have to order a new T-belt pulley that is of solid stock. After a lot of digging I found out that the one-way bearing has only 13lbs of torque. How is this supposed to stand up to a 4-stroke engine even if it is only 49cc's? I bought 2 kits, one for a Huffy Traveler and one for an Electra 7-speed Cruiser with a Jackshift kit. Once I beef up my transmissions I hope to alternate them for commuting to work.
