Hello everyone. Took advantage of the great temps here in NJ today and went on a first long ride of the season. Noticed for the first time some oil on the fins of the head and block (more on the head) on the right side wrapping around to the back. it started to rain when I got home so i'll look at it tomorrow. Someone I was riding with suggested it was possibly being blown from the air filter having had oil in it from the crankcase breather hose. It's easy to check but thought I would check in here. Would appreciate any thoughts on this or other possibilities. Thanks so much.
