Vulcan 1600 engine noise
I used Castrol GTX 10W 40 petroleum based, 3.3 quarts w/filter change, per the book. I have used petroleum based oils in the past, with no problems. I did pull out the oil screen where perhaps a few oz. of oil came out as well.
However, the oil level is within range. The noise does sound like there is not enough oil in the machine, but the oil window says otherwise. I plan to take to the dealer this weekend and have them look at it.
Question, does the transmission use the same engine oil for lubrication as the engine itself? I was told that it does.
PS, the bike has run great with no problems, even with the noise. There is no oil light on or any other lights on the dash.
