I made the mistake when I had my 4PT. I filled to the full level when cold and it dumped tons into the airfilter box and ran VERY badly! Once I'd dumped the excess and ran it for a while it constantly checking it through being paranoid, it finally settled. When starting it in the morning I KNEW there was oil in it even though it didn't show on the dipstick as it does settle back down into the engine (there was nothing wrong with it)and without a very obvious puddle below the bike I knew I'd be good to run it for a mile or two to the fuel stop where I could check. I also permenantly removed the plastic cover and stored it away for ease of access. I did 20,000+ kms on it and it's still running in Africa with a new owner.

As mentioned above, check it when your at the petrol station without letting it settle. Turn off the ignition, whilst still on the bike check the level, then fill with fuel. I found this helps get a routine of checking it also and note the oil burn rate. Once your at an acceptable level it's possible to remove the oil cap without it pissing all over the place. If your not sure, I'd have the oil level at the halfway mark, when it's not too much and not too little until your fully happy to raise the level yourself.

Checking the airbox frequently for excess oil also is good practice and the oil drain pipe situated below.

Hope this helps.

P.s The manual is crap for checking the level, disregard and run for at least a mile and don't let it settle.
