Francis,
Welcome to the V11 Scura world. These bikes are easy to maintain without specialist knowledge. I can service mine and I have 10 thumbs!
I did my first service at 1,200km, oil, filter, valves and cleaned screen in sump.
You may not need a sump gasket but it is handy to have one and rocker cover gaskets as well.
I have used TLM who advertise on this site for all my spares including workshop manual.
Regards from a cold Ireland,
John
