Oil. oil filter. air filter and plugs in the C1 roller skate. Drained the oil using a 12v pump for the first time.
Slow and more trouble than its worth is my conclusuion. I took the sump plug out when it had finished its work, and got another cupful of old oil out. 
Just need to install the DAB wireless and ariel now and then hopefully all done until MOT next January..................yeah, like thats going to happen.

I really must drain the sump on the Big Black Pussy, after all, I've probably had it 5 or 6 years now.
But the undertrays are stupidly long, and a pain to remove without a lift, so I suspect I'll keep sucking it out instead. I guess the advantage of that engine is it has a proper sucky tube, which makes it trivial. Obviously, I'd rather have a dipstick instead, but ho hum.
