Hi

I am troubleshooting a spark issue. Is the spark pulse area supposed to have oil in it?
Hello Howdy goatman. This forum mainly deals with the 2010-2020 CB1100 series of bikes, but maybe someone will know the answer to your question as it pertains to an older Honda
There's no crankshaft seal on that left side, but the left cover has a gasket and the smaller cover has an o-ring, so there is some oil in there that should be okay.

That generation of Honda 650/750/900/1000 had a pair of igniter boxes that often fail over time, with the epoxy potting melting to goo.
Nevertheless goatman64, welcome to the Forum!

Don't look too hard at the CB1100. It might cause conflict. Smile
