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.
