Decided to take the oil tank off today, and drained the engine oil. I knew I was going to make an oily mess so I put down an old bit of carpet in the middle of the back yard and went to park the bike on it. Rolled it off the centre-stand...
Now, those up to date with this account will have realised my error. For those not quite up to speed, here's a pic of some parts of mine I posted earlier in the thread.. to help you guess what happened next.
Yes dear reader, call it a Senior Moment, call it a rush of blood to the head, call it bloody stupid, but I'd forgotten there was no rear end attached to the bike.
Luckily, thanks to the partly seized centrestand axle pin the bike didn't really crash to the ground, but made stately, almost regal progress in a downward manner.
Due to my rippling, manly muscles (or lack thereof) I used a wooden prop to help lever it back up and managed to get the centrestand back down. No damage done.
So, oil tank off and currently getting de-rusted. The oil hoses were a bit horrible so I cleaned up the metal parts with a rotary wire brush. I tried black boot polish on the fabric covering the hoses and it seems to have worked very well. Before and after:
