Just an fyi its very difficult to get heavy springs on forks other than ktm. I tried with kyb from a yz450 and the cost was prohibitive. Since the same basic forks from ktm are used on lots of bikes big and small you can usually get anything you want with a call to slavens. Been there thats why I only use ktm suspension on my builds.
I know there are triple clamps made for airheads on a custom basis by rdubb check the vendors for his thread. Not cheap, but neither is building a bike.
Having a tubing bender is awesome. I have the jd2 model three and I love it. Dies are very expensive though. So is driving back and forth to your buddies to tweak a bend three more degrees.
I've never converted a shaft drive, chain seems so much easier but love to see your project
We're not out here to rough it. We're here to smooth it. Things are rough enough in town.
