Hmm. My wife just arrived home and that gave me an idea (no, not THAT idea

) Just get her to hold the bike up while I lube the chain

I'm joking. She keeps a small bottle jack in her car so with the bike on the sidestand I tried jacking the right hand frame tube (by the ctr stand pivot) slightly to raise the rear wheel just clear of the ground. It works great and will do me just fine. Thanks for the input
