The tank's a purdy purple finished with only the very best Krylon paint, from Wal-Mart I'm sure. I found out that not only does 'The Works' work on the inside, but also on the lovely paint job as well. It's an extra that I'm just playing around with while waiting for my brake parts to arrive.
The petcock was advertised as a CB550 (albeit a '74; which I thought was the same tank as '75). However, it sure don't look like it will fit. I wonder what it's for.
