Ok. So the motor is broken in and ran 2 tanks at 32:1. Dropped down to 16:1. Took the bike for a good 15 mile ride over the weekend and after returning there was an amount of oil on the top of the head, opposite of the spark plug and above the exhaust. Everything ran well and had no overheating but the chain did pop off once but my new tensioner should fix that. Just checkking what could cause this. Top of the head is tight, same with the exhaust.
