Does sound like tight spots in the chain. Was it very loose previously, and is it correct now? 30-40mm, for a 98-99 FZS600, and 30-45mm for a 2000 on bike.
Especially when the chain is worn, you need to check it at a few points, as tight spots can make a massive difference - when my chain was knackered, I could adjust it at one point to be correct, then rotate the back wheel a quarter turn and the cahin would be tighter than a gnats wotsit. So then you're into compromise territory - but it really does mean new chain & sprockets are needed asap.
