Even though the originals were badly cracked and deep none of the cracks appeared to go all the way through, but the vacuum take off plugs were shot (as Fazerider also said in his post) and that was most likely causing the rough running.
When I went to remove the vacuum take off plugs the tops came away even though they looked ok. I replaced with new Yamaha ones and they cost £10 for 4 including delivery
Sorry to dig up old thread but wondering where you got the vacuum plugs? Had a dig around the breakers on ebay to no avail.
