Sorted another small pile of parts for the Kawasaki KZ650 project.
First in the list is eight Honda flange cap nuts (high type). As long as bolts, nuts or other fasteners fit the application and my design, I do not care much about if they were made by Honda or Kawasaki or Yamaha.
I prefer flanged cap nuts for exhaust headers, they keep exhaust suds protected from water and mud. These M6 nuts were used to mount exhaust headers in several Honda motorcycles. They are chrome plated and in my opinion perfectly fit early type KZ650 exhaust header holders.
Next is the PMC plug for the cylinder head tachometer port. I had to plug that port and I might have made the plug of my own design. However, I was already overloaded with work and simple calculations (time to make drawings, buy raw materials, visit lathe/milling shop plus payment for turner work) showed me that in such circumstances the option to buy PMC ready solution will be cheaper. And here it is in its packaging:
It is made of stainless steel and it is neatly made little thing. I am pretty impressed by its high quality and design: it is equipped with two O-rings, it is additionally lightened ( by means of hollow body and recess in the front end) and each edge of part is chamfered.
