No. Bone stock internals. At some point, a rebuild or replacement will become necessary. Last time I did head gaskets, I found one of the portside cylinders pretty badly scored on the bottom side. Not scary bad, just bad enough to be psychologically bothersome.
It, like most four-cylinder wings, smokes a bit on start up out that left side. So, I don’t know if it’s normal four-cylinder Goldwing smoke or the scoring is contributing. I’ll get a few more years out of it before I need to make a decision.
