I can confirm my chain was doing the same when i lubed it up the other day,
Had me worrying a bit after reading another recent post about chains jumping but it was totally fine when i took it out for a spin.
Only trouble i had was trying to get the back wheel off of the ground,its because i jacked it up with new wishbones,i had to centre stand it on a slight downwards slope to get it up enough to spin freely, worth it though.
