Fuel tap is in the middle, but the sides are smooth not inset for the knees. I’m wondering what this tank is now! Sent from my iPhone using Tapatalk
I'm thinking it could be an early CB250 tank now, would know better seeing a pic of the underside. Could also be a 750 tank, taps on the right side and it looks to be the same tap as the 500/750. Is that pipe running across the top of the engine a link pipe to the other side of the tank?
