New to the forum and 450 dirt bikes. Recently bought a 2010 YZ450F bike and love it. I failed to notice the oil leak when looking the bike over, and I'm wondering if this problem is simple, or needs to be taken to a shop to be torn down. On a scale from 1-10 of my mechanical skills, I'd say I'm a 4. The pic shows the oil leak; looks like the left side crankcase cover. Are these plastic plugs and oil seals, or is this something related to a cracked case and I'm looking at a rebuild? Any help for this newbie would be appreciated. Thanks!
