The first thing you need to do is download the service manual from the "general support" section of this forum. Then you need to find the section about removing the clutch cover and the kick starter. Once you've got the clutch cover off, you can determine what's wrong with your cover and kick starter assembly.
If it's just the oil seal torn, you can either order a single seal from the dealer or a seal kit off of Ebay.
If the clutch cover is worn out, you'll need to find a new clutch cover and the same applies to the kick starter assembly.
