The original CB1100

[use2b_imp]

So, use2b, yours came from Europe perhaps? The AD suffix suggests ABS and 2013.

that is the only explanation for the factory silver engine as it is surely not painted, not a hint of that anywhere. also polished aluminum front sprocket cover
BTW my CB750K is on the way to the UK now in a shipping container which is probably how this one arrived. we have a local man who ships cars and bikes back and forth so it must be easy

the guy i bought it from sales a lot of bikes and parts on Ebay . He said the builder died from a heart attack and he bought it at an estate sale . back on subject this new seat was soooo hard and took some breaking in so i hope things go well for Guth
