I keep saying its no good standing still

I have in the past bought low mileage bikes which have had issues. One bike as it had been standing outside the rear suspension rod had rusted. After a little use the seal went and the shock was no good. Which brings meemories as i now look at my bike and as it has been outside for four weeks. I can see on the aluminium the white dust starting to appear and that i have not been out on the bike. After the install of new pads and brake fluid the brakes need to be beaded in. I have cleaned the bike and sprayed with a wd40 type fluid. The miles are 23k and trying to turn the bike over was a bit slow. It fired into life....
