My problem is that the left handlebar is bent. Sure the forks are froze-up but I just want the handlebar straight at this point. Someone tried to heat them and straighten them but they failed, probably ruining the steel's temper and weakening the handlebar. Plus my frame has been modified poorly. I'd like to upgrade to straight and unmodified original forks first, and then a frame or both at the same time.
Try a site called xenoahs ark. It's a Rupp site and they will tell you anything you want to know. It sounds like a sketchy name but Xenoah was a motor Rupp used in their later snowmobiles and the company still makes small R/c and industrial motors. There's a great bunch of folk on there, Brian
