Howdy just wanted to introduce myself, name is Sue and I've been riding a scooter for about 5 years now. Been living in wonderful South Carolina for about ten years now about 15 miles from Myrtle Beach. I love riding, but don't like paying so much money for a bunch of plastic that starts falling apart 2 months after purchase. Yes, I buy the cheap Japanese ones, but I'm a full time student kind of hard to save a few grand for a decent scooter. Thinking about investing in a four stroke bicycle engine kit and have no idea where to start looking for a durable and reliable engine kit. I know that I don't want a 2 stroke because of the mixed gas situation and less gas mileage. Have a mountain bike that I was hoping to install the engine kit on. Will continue to read the forums. Thanks, any advice is appreciated!! May every rider be safe.
