Below is a photo of the lower left front fork tube from my 1966 CB77. Earlier design. I'm getting ready to powder coat it (and a bunch of other parts). I know many on this forum will say I should paint instead of powder coat. I agree painting would be nicer, but time and money considerations are steering me strongly toward powder coating. My concern is whether there is anything heat sensitive at the bottom of the tube - like an o-ring, for example. Is the inner tube welded in place?
