I think of clutch fade as things actually getting tighter. For example, the clutch works great, until the bike gets hot and things expand. Once things have expanded, I hear that hissing noise which in my mind sounds like things that were once within tolerance have now expanded out of tolerance.

I have done a lot to bikes, but I only know the basics of transmissions. I have adjusted the clutch lever so that I have oh, 1/4" of play before the clutch engages.

Should I tighten the clutch lever to have nearly no play? Is it possible that these bikes can only go so long and get so hot before things start to get way out of tolerance?

The hissing noise sounds a lot like something spinning making slight contact with something else.

The transmission has always been very chunky and clunky. When I shift down coming to stop light into say 2nd gear the bike gives a loud CLUNK and creates a whirring noise. That's with the clutch PULLED IN.

Try setting the clutch with about 1/8" or less play when cold. When it arms up the play will increase.
