Two good suggestions from Fazerider. If you take the spark plugs out you will be able to turn the engine over easier but still feel anything odd. Also running on the centre stand shouldn't do any more damage than running under load like you have been doing. Don't let the chain thrashing about worry you as that is normal with no load on it. Applying a bit of back brake should settle the chain and help indicate the problem if it is gear related.
