1976 KZ 900 #4 plug fouling

He said it doesn't smoke at all, so I would think rings or valve seals would be ruled out. He has 125 psi on all 4 cylinders. The only thing he was wonder is if the valves adjustments are tight, would that cause a plug to foul? I think he plans on adjusting #4, but just has not gotten the shims yet... He mentioned he is wondering if the timing is off somehow...?

...76 KZ 900...fouling issue on the #4 plug...swapped plugs/wires/coils with other cylinders and swapped carbs (apparently 2/4 carbs are interchangable on these bikes?)...issue stays with #4...doesn't smoke...125 psi on all 4 cylinders. The only thing he was wonder is if the valves adjustments are tight, would that cause a plug to foul? I think he plans on adjusting #4, but just has not gotten the shims yet... He mentioned he is wondering if the timing is off somehow...?
Too tight valve could result in reported problem.
Don't need shims to measure existing clearance.
Likely not a timing issue.
Good Fortune!

He isn't a mechanic, just a guy that knows how to work on bikes. I'll confirm what he's referring to and get back to you.
