I haven't seen it this cheap online, but I haven't looked around at the local places yet. I think I'll buy it just to get the thing roadworthy. I may also try sticking one of the stock 97cc doodle motors on an unused kart for my kids. I know, they're boat anchors, but I'm gonna try it. They'll be riding it on pavement, so hopefully it will work.
Thanks, OND. I appreciate the speedy reply!
