I have managed to remove the fuel tank (thanks to tips on here: unplug fuel pump, turn engine over a few times to relive pressure, together push fuel pipe towards red connecter + push collar away from red connector, this make it possible to then slide the pipe away from the red connector and it very easy... don't force it
So now I've removed the airbox two things stand out: 1) The foam from under the tank is being sucked into the airbox
and 2) there is a lot of oil in the airbox and around the vapour recovery thing.
Question: Is it safe to remove this (presumably) heat resistant foam?
and should i removed the oil vapour recovery box (in the photo) and clean it somehow - seems to be sealed, does it drain back to crack case??
Spray it out with carb cleaner???
PS Does anyone know what the unused plugs are for?
