I am new to bike's so please forgive me on not knowing the correct terms for the oil leak area.  It is a bolt behind the kickstand that seems to leak a few drops after I ride it for a while.  After it cools off it will not leak anymore.  I would appreciate any help on this matter.

shift shaft leak?  I think rob and someone else has this minor problem.  

Are you sure it's not coming from the timing inspection cover on the case?  If it's not tight enough or has a pinched oring, it'll leak.

Thanks for the replies.  It looks like a bolt but when i turn it to tighten or loosen it does nothing but turn.  It does not feel like it is tightening or loosening and it does not leak everytime I ride.

Black light reactive oil additive.  Glows in black light.  Breaks down in oil in a week so you won't have to worry about it if you spring a leak next month.

What size wrench fits on this bolt that doesn't tighten? ???

I went & looked at mine. I think you are messing with the bolt that goes theu the plate the right peg mounts on. If you will get a 17 MM wrench or, I know I will hear howls of protest, but 11/16ths might get ya thru iof you dont have the 17mm,to use for a backup. I wouldnt recommend using it for the primary tool, but only backup. Tighten with the 9/16ths if ya dont have a 15 mm, on the one behind the sidestand. I think this helps "Pinch" the case & could allow a leak if loose.

On second thought...if it is a leak that stops after the bike has been sitting, then it probably isn't the drain plug.  Take a look under the front pulley cover.

If the starter has ever been pulled, it could be a bad starter o-ring.
