I'm going to do my first 600 mile oil change this weekend and noticed about 4 bolts underneath the bike that all look like drain plugs. I know which one is the engine oil drain plug but what are the others for? My understanding is that you just drain the engine oil plug and that will drain all the fluids in the motor/clutch. Sorry for the ignorance but I have never seen so many "drain plugs" in such a small radius. lol

They appear to have crush washers on them and they are the size of the engine oil drain plug so I would doubt it. I just glanced at it earlier, I guess I need to really look at them.

So I'm curious if anyone ever managed to figure out what the other bolts are underneath the oil pan? I've searched throughout the manual only to come up short! IMO I think they could be oil check valves of some sort...

On page 5-74 of the manual.. it shows 3 bolts w/washers... they are only mentioned as "New"... they are not in the list column... strange...

I think that means when reassembly, use new washers. Must be some type of crush washer.

Personally I would not mess with the extra bolts on bottom cover. They are most likely bolts and not plugs and are sealed with bronze washers so they don't leak. Also those bolts most likely hold an internal engine component to the inside of crankcase. Could be huge mistake taking them out.
