| Yes thats virtually it. There are several techniques.. I prefer to....
run the bike, or change the oil after a run. Let the bike stand so its warm enough for the oil to flow freely, but not too cold, before removing the drain plug. Mind your hands!! Once removed, you could even let it drain overnight to get every last bit out.
You may well need a special tool (ooh er) to remove the filter, you can get them from halfords for a nominal fee. There are of course several types of these, i use a strap wrench, but you can use the grip type successfully.
When replacing the filter, prime it, ie fill it up with oil before screwing it on, and wipe a little oil on the sealing ring to aid tightening it up. Do this hand F tight! |
