1981 GS650 chopper/bobber project

[duaneage]

At least it was an L model, if it was a katana we would be coming for you. I would look at tanks for the 450L if you need a smaller tank, similar design but just different enough to work.

You do good work, you anticipated the stress on that part and designed it accordingly. Buy a seat with the largest springs you can fit.

Mocked up with tank/seat/bars:

Yeah the tank is too big for a hardtailed stock wheel base bike. If you are going as far as you already are cut the triple back bone out and weld in a single piece of tubing. You will have a ton of tanks to pick from that way. I mounted the sportster tank on mine and I don't like the way it sits. After my cafe is done I'll be cutting the back bone out of my 650 to let the tank sit lower.

Wowza, you mean business!

Out of curiosity, what did you do with the luggage rack you took off?
