And here are some detailed photos of the Kawasaki KZ650 engine.
For all polished covers I chose chrome plated small hex head flange bolts. These are genuine Kawasaki bolts with length identical to the length of original screws. Chrome plated bolts look awesome.
I picked bolts of the same design even for the PMC tachometer port plug.
And starter motor cover.
For intake manifolds I chose small hex head flange bolts in black colour.
As for the painted parts, I chose Kawasaki ZR7 flanged bolts that come zinc plated but in matte finish.
New genuine exhaust holders in combination with Honda high flanged cap nuts look great too:
Oil temperature gauge installed in place of oil filler plug.
And a few more photos (including some with reflections in polished covers) wouldn’t hurt.

Such a high standard of workmanship. It really is something you should be proud of. It is obvious that you have taken many many hours to achieve the results we see here. Excellent attention to detail.
Thank you! Hope one day (after the war ends) I’ll return to this project of mine.
