I would guess that it's a European market Yamaha XJ600 (not the
Diversion model, though!) with a set of secondhand carburetors on it.

I'm stunned. What is the common problem? It is an XJ600 non diversion
model. Except it has it's original (as far as I know) carburettors. It
at least has managed 16,000 miles in my hands and 36,000 before that.
