Shit just typed a page of info and lost the draft. F _ _ K
here is a video I posted a couple weeks ago.
Reb, I cleaned and lubed the variator per your tutorial, and it runs smoothly. I didn't film turning the engine over without the plug, but there was some crunchiness to it.
Not sure how I can measure roundness on the clutch, the pads are worn evenly, with zero residue, no glazing, so i think the clutch is ok.
I looked up this old thread, and it sounds just like my bikes. With the 79 you can hold a conversation over the sound of the motor but the 78 buzzes like crazy.
hopefully this link works.
