I was coming from the gas station and heard a little bump, thought it was one of the lowering links scraping the ground so i really didnt pay much attention to it. When i changed gears the rear wheel wanted to spin out, so when i got home i looked under the bike and thats when i saw the oil pan was busted...smh. I was pissed beyond belief when i saw oil pouring from around the drain plug. How easy/difficult is it to change the oil pan? and how much am i looking to spend to get it replaced?
