RE: ZXX engine interference
Well, as long as the lining is bonded evenly all the way around and the clutch isnt dragging like it was before it should be okay. I think I got one wrap of electrical tape on mine with the newer lining and two with some older lining that came with my ZX. The main thing is that there is no high spots that can cause uneven clutch engagement and vibration.
Sounds like it should be okay. Even the article mentioned 1to 3 pieces of paper was good.
I'll go ahead and give you a thumbs up because I want to see you get that bird back in the air!
