New user for help and advice

Hi new user so I thought I’d introduce myself. New to Ducati as I’ve bought a partly finished 600ss cafe racer.
So as its been sitting for a few years i thought I’d carry out some maint before rebuilding. The bike is a runner.
Has anyone any good spares sites (belts, batteries) ?
I’m upgrading the front brakes, line and master cylinder.
Also looking for a carb strip, service and set up. I’m sure some of the rubber parts will be perished.
I’m not a novice mechanic, I worked as a engineering technician for 36 years after completing my apprentership. Recently (within 13 yrs) I built and run my own club racing team.
I look forward to asking for advice, and hopefully recieving some…lol
