I have an '87 1200 Aspencade and I've noticed a ticking from the heads, it used to be on the left side but now I think it's starting on the right too. I posted something similar to this a couple months ago and someone suggested the exhaust gaskets might be leaking causing the ticking sound so I replaced those and no change. I talked with a friend who used to work on Goldwings and he suggested using 20 50 oil, didn't make much difference. He also said that at least on the 1200's, Honda machined the holes too deep sometimes and so there's too much room for the adjuster which will cause it to click when the lifter hits it. He said I could try shimming it to see if I could get the free play out of it. Has any one had this issue and if so what was the resolution? I've been told that's "just the way they are" but I don't know if that's true either. Are there any negative long term effects from not addressing this situation? Love to hear any suggestions. thanks in advance.
