Very cool.  Thanks for the photos.

Back in the 80's I did this to a 1977 IT400. My dad says the IT400 was a heavy

bike that wasn't good on tight trails because of the weight. He bought a brand new one and didn't think much about it. I thought it should look like an early pre YZ factory works bike from 1973.
I never did get a 1974 YZ tank for it like I was planning to finish the illusion.
