Something I thought about while reading another thread, and the above post.I switched to a synthetic oil the last change awhile back. Normally used Mobil Delvac....
During my travels the bike sits for 10-14 days at a time. I ride couple hundred miles, it sits for weeks, ride and sits. Perhaps the oil is not lasting that way.
It's only been 2k miles but around 6mths old.
I am going to switch back to Mobil Delvac this weekend and also do the above recommended test.
I will check for leaks, don't quite know how...but I will check.
