I recently got my bike running and i have since noticed another slight oil leak when i park it. I get a couple of drops on the ground as soon as i park it but not much after that. I need to replace the crush washers and want to cover as many of these possible causes as i can while i have the bike drained so i dont have to drain it again. Im going to give it a good cleaning and check under the left enginer cover for other possible leaks before doing this. (blue) Can i pull the the cover of the starter assembly off and replace the gasket without messing with anything behind it? This schematic makes me think there is an oil seal behind the cover but i can find much on how it goes together. (red) What is the stud with the nut? Can i remove it without mesing up whatever it's holding? Can/should i replace that washer with a copper ? Should i just loosen and retorque it? do you have a torque spec? (green) What are these two nuts holding? Can i remove them without mesing up whatever they're holding? Can/should i replace the crush washers? Should i just loosen and retorque them? do you have a torque spec?
