oil in left baffle

[upside22]

Particulars: 2007 Nomad 1600, V&H Baggers, Cobra fuel processor, Caddman mod on air filters, 42000 mi., oil change about 2000mi ago, Rotella T-6.

The oil is down a little in the sight glass since the last oil change, maybe 1/8". So it's not been using much. No visible oil leaks anywhere on the Nomad.

I've been riding in some pretty dirty conditions the last couple of weeks so got the Nomad out to wash her. Had it started for about 30 sec to pull out of the garage down into the driveway to wash it.

When wiping it down after hosing it off I noticed the left baffle was a lot darker than the right one. I wiped my finger on the baffle and it came away with enough oil to drip off my finger.

So I pulled the plugs to see if I was getting any oil fouling from a leaking oil ring or valve guide. The plugs look pretty good. A real light brown that is not wet. No dark deposits up inside the plug. No visible oil at all. If anything I would say it's been running just slightly rich.

Does the left side muffler tend to collect oil till everything is at operating temp (because of the two right angle bends)? How long should there be oil blowby when riding in 35-40deg weather?

Is this something to worry about or should I take it out for a 100mi interstate run and see if everything burns out or if it still shows oil?
