It's quite simple go buy a new oil filter it will say "THIS SIDE OUT" on it on the right hand side of the engine is a round louvered cover held on by three 10mm bolts, on the bottom of the engine is a bolt in the center of the crank case that is the drain.. do not overtighten it when your installing it or you will be posting up "How do I fix a stripped drain plug?" remove the cover on the side gaining access to the filter remove and insert the new filter put the cove back on making sure not to damage any gaskets or O-rings. tighten everything back up and grab a couple of quarts of approved Honda oil I use GN4 10w30 and fill it to the required level. Start it up ride around the yard easy stop and recheck top off if needed...Your done

when you take the filter off there will be a spring behind it so dont lose that and you will need a little less than 2 quarts of oil [go with honda oil]

I don't know about all hondas, but on a 300EX, you are NOT supposed to screw it in. You just put it down in the hole until the threads tip. Don't screw it in. Make sure it is perfectly level, though, or your reading will be off.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
