Hey thanks for the kind words Gaternapper, you should see the KZ, it will be done in a about two weeks and im going with a green candy paint that looks stunning in the sun.
Regarding the breadbox tank. The Bonneville in question was originally sold in the UK and the tank is original. I like it over the american round for two reasons. First, I'm building a one off custom cafe bike and the square tank fits the lines of the design, and second, it holds a lot more fuel, nearly 4 gallons. I like having a 200 plus range.
Update, I am planning to run a hydraulic clutch on this bike. I found a company that makes an internal slave cylinder. www.flatlandcycles.com
Now I can use brembo masters up top on both sides for a real sweet look.
Side note: I have been doing a mild restoration on a 76KZ400 over the past two weeks (filling my need for wrenches while the bonne is at the engine builder/ powder coater) and although I think this is a cute little copy of a triumph, it simply is not. You get what you pay for rings true.
