On the Z it's 1.9l of oil for the first stage of filling and I have to say the two times I tried to get 1.9 in it always dribbled out and all over the radiator. I now put 1.75 in at the first stage and have no problems with spillage, then top up to 2.6l, put do it in stages to avoid overfilling. The capacities in the handbook seem to be a little on the "rough side". Better to err on the cautious side, and remember you won't be able to check the exact level of your newly replenished oil until you've actually ridden the bike and gone through the whole level checking fiasco!

I think my main dealer has the same problem, because the one and only time they changed my oil the rad was covered in oil and it sprayed all over my right leg on the way home!

Racing it = revving it!

If your careful ad the o-rings (2) under the filter cover look ok, you'll get away with reusing them the first time. I'm working on replacing them every other change. However, they are only a matter of pence, so it wouldn't break the bank to change them.

(Little tip: Don't remove the cover, or the filler cap until most of the oil has drained or it will go everywhere fast.)

You should be OK without a torque wrench, just don't over do it. You can always nip them up if they weep later.
