This is my first post in these forums, See I need a little help. Went out to go riding the other day and noticed a rather large puddle of oil under my 200SX. Checked the oil drainage bolt, it was tight. thought I might have a bad gasket somwhere. But I had my chain pop off the day befor while I was running thru a field jumping, Could the chain have cracked the case?. Any help would be greatly appreciated
