No problem !
First, the drain plug is at the backside of the oil pan, there should be an allen wrench looking plug (I think it's a 6 mm), remove it, and the oil will come out, there's an aluminum crush washer, that's the seal for the drain plug .
The oil filter in on the right side of the engine near the front, under a triangular looking plate with three 10 mm bolts holding it on .
Remove the bolts, and have a drain pan under there, because you will get a fair amount of oil out of there .
Remove the plate/cover, extract the filter, and take a good look inside the filter cavity, to see if there are any o-rings on the hollow pipe in the middle of the area .
The original filters didn't have integral seals on the filter, you had to put an o-ring on the pipe, then put the filter on, so there's a remote chance there may be one still in there .
Clean the cover up, if it needs it, then lube the tube type seals on the oil filter, insert it on the pipe , next put the thin large metal washer into the cavity, and make sure it stays up against the small lip that sticks out a bit, lube up the o-ring, and place it on the cover, and then re-install the filter cover, put the three bolts back in, and tighten them up .
Remember you are threading a steel bolt into an aluminum case, stripping the soft metal threads out, isn't hard to do .
Fill the oil back up to the full mark, and start the engine, and check for leaks .
If you don't know this, to check the oil level, the bike needs to be on the center stand, remove the dip stick wipe off the oil, and then place the dip stick back on the engine, don't thread it back in, just let it rest on the threads .
Some bikes don't like to have the oil level at the full level, they just burn it down a ways, and it settles in somewhere in the middle of the range, just have to see how your bike acts in this respect .
