I tried to strip one and gave up trying to put it back together, purchased s/h one off EBay cheep and it works but not that nice Honda sound so purchased another and just the same sounds but not that good. They should sound real nice when they work well.
Yes I fitted a small modern horn into the old case but not happy with it so that was put aside.
Only strip a CB72/77 horn down if you must BUT you may regret it they are not easy to put back together.
