First thing to check is your valve clearances.  If that's not it, I'm thinking you might be a tooth off on your cam chain and sprockets but it's been ages since I have performed that check or timed a machine like this so I'll let the rest of the community guide you on this.   Good luck, I'm sure it's a minor issue.  See if you can get hold of a service manual, that will guide you.
