I just thought I would share my experience with an oil leak on my 2011 vrod muscle. I could of swore that I had a head gasket leak it looked like it was dripping right from the seem where the cylinders meet the block on the right side. I cleaned it up and went for another short ride and there it was again. I started doing some research on vrod oil leaks and a lot of people stood by the revo engine said shouldn't leak. I then did some more research and found a you tube video on a oil change on a vrod there was on thing on the video that stood out to me and that was the amount of oil I should of put in while the bike was cold. I pulled out my manual the manual said that the oil level should be half way up or a little less on the cross hatch markings on the dip stick. Not being that experienced with working on bikes I was pretty sure this might have something to do with my oil leak. I pulled the air box off and found a good sized puddle of oil on the floor of the filter box. I cleaned every thing out with degreaser and rags, and blew out the breather valve as best as I could. I also ended up having to drain about a 1/2 quart of oil out of the pan. I put everything back together and went for a 20 min cruise on freeway, came back and did a thorough inspection on the bike I even took the air box cover back off. No oil anywhere not even a speck. For those of you who are experienced with bike repair this may seem like a no brainer. I seem to learn everything the hard way. I know now that with the manual says 5 quart capacity it is not necessarily 5 quarts it may be quite a bit less. The moral of the story things might not look as it seems. The oil leak that I saw looked just like a head gasket leak, it really looked like it was running out of the head gasket but in reality it was running down from above, down between the cylinder (which is hard to see) and then followed the angled ridge along the head gasket. I am so happy it was an easy fix did not cost me anything (although I probably will replace the breather valve). I find these forums helpful and may save some us from having to spend big $$$$$$$$ at the HD dealer. Have a great Christmas I just received my present I am back on the road!!!!!!!!!!!!!!!!!
