Cool project. I had never seen a silver wing frame before, looks like it is much nicer/better suited to custom builds than the more popular cx500. Rock on!
Thanks man. Yup, flatter than an Illinois cornfield.

Adjusted timing chain at lunch today. I was afraid to loosen the bolt too much... I went about 4 turns out. Maybe I didn't go far enough or maybe the tensioner was just stuck from not being adjusted? I let it run for a bit to warm up, I'll adjust again and see if maybe running for a loosened something up... or maybe it's better and that's valvetrain noise?
