Hi Spiros, great progress of a great bike. Attached is a photo of a full size K0 that I did a paint restoration on for a client a few years ago for your reference. This had the color painted headlight mounting as well as painted headlight. The later K1 had the chromed mounting and a black headlight. The reference above referring to the airbox is also correct.

Fuel tank, side covers painted silver (together with some touch ups)...

Thanks my friend @johnb!

Looks really great already, Spiros @fiveten
Once the ejector pins are gone it is a perfect saddle.

Exhausts under preparation...

Thanks my friend @chinesegeorge! Indeed, there is more detail.

Swingarm and shock absorbers do look perfect, Spiros @fiveten

Front section gradually put together...
