Took the bike out for a quick 10 mile ride yesterday. Parked for about 30 minutes and when I went to get back on the bike I noticed a small puddle of oil on the ground. Thanks to previous posts on the forum I was able to narrow the location down to either the 2nd rocker box gasket or comming out of the middle of rocker box( I forget what that part is called). Question is if it is comming out of the middle part that's because there is too much oil in the bike. Is this correct to assume or what else would cause it?
