I've been reading this forum, and waiting for my engine kit to get here. I'm eager to get this thing built. I'm using a jet stealth 66cc/80cc from zoombicycles.com. I decided to go with a next all terrain sport for the bike, mostly because I already own it and it seems easier than my other option the next avalon for my first build. it's good to see other people are into this, making it all the more fun.
