Irregular knocking noise
Hello everyone
I've an issue with my '92 Heritage. Only when engine is hot and only when idling there are some irregular knocking noises I think in front rockerbox.

Your lifters do sound pretty loud but what's that tap tap tap tap that I keep hearing, like randomly 4 in a row.. Sounds like you're taking a wrench and banging it on the tank or something.. If that indeed is the noise you're talking about you better start looking at that cam chest really quick..
