Silly question i know ... but ( few silly questions )

[Ozboc]

My bike (2000 model)didn't come with a standard owners manual pointing out a few of the obvious things , so i shall ask here, knowing i may receive some ridicule , but here goes.

Oil level - how do i check the oil level- on the right when sitting on bike is a cap that when open just shows me the top of the clutch basket ....(filling point)

Fuel gauge - when it goes to empty does a light eliminate showing ultra low tank -- and if so -- how many kms after the light is on on average before it comes to a stop ....

On the instrument panel - above the speedo and between blinker indicators is a light "F1" what is this for ?

- i shall also be doing a service on the bike as i am not sure when it was done by previous owner , so want to be safer than sorry - any suggestions for any pain in the bum things that i may come across ?

thanks in advanced
