Howdy, So i had a crack at changing the oil in the zzr250 thisafternoon. Was OK for a first run i think. Went to sydney city and got some oil and a filter with a new sump washer. Get home, ride for about 15 mins to get the oil warm so it will come out easy. Come home, put her on the centre stand, grab socket set, put of newspaper down for the odd drip. The socket i have is to large to get over the sump and inbetween the filter. So i loosen the filter first and let that drain for a few mins, take the filter out. Take the sump out and let the rest drain. doing OK so far, an Ant bit me on the arse while i was on the ground, im ok however. Oil out, put the sump back in, change the filter, tighten it all up. Feeling pretty good abaout myself at this point. Fill her up, start her up and go for a ride. nice, actually feels better (may be all in my head tho) come home and pack up...whats this little thing.....ah, that would be the new sump washer. Go back over to the bike and there are a few drips on the driveway. put the bike away as i had to come to work and put some cardboard under her to catch any more. Ive called the housemate who has checked and its only 3 drips under the bike. I will redump the oil and replace the washer in a few days. Has anyone else done this before? I feel pretty silly, bit it could of been worse i guess!
