I use K&N oil filters...3/8" extension (6") on the end of a ratchet works fine. Look at your old filter to make sure the sealing gasket is still on the filter, and not stuck up in the seating boss, if it is, you want to dig it out and not scratch the surface that it has adhered to.
Just make sure you line up the cooling fins on the oil filter cover with those on the bottom of the sump.
Get a long narrow funnel to pour the oil into the engine.
If you dont have cats, buy some kitty litter at wally world to throw down on the oil that you are going to spill ( yes, you ARE going to spill some oil).
Make sure you have the bike on the centerstand to perform your task...no fun trying to shake oil out of the bike if you started the job on the sidestand.
Once finished, and the obligitory test ride is completed, you can now thump your chest, explain to the SO how hard it was, and apologize for ruining her favorite dishrag, then crack a beer, and all will be fine in the world again.
Cheers mate !
