Hi Tim,
Motor is looking good. I noticed you have a new set of cam followers. Do yourself a favour and have the followers reground. The problem being they are not ground correctly, even though they are new. No matter where you get them from, the are all made by the same company. Take them down to Clive Cams and tell him I sent you down. He's a good friend of mine and will sort you out. Or if you would rather, send them to me and I'll grind them correctly for you.
There is a problem with the followers being sold out of the UK not being correct. I have just organised a cam follower facer to be shipping to Keith Calver as there is no one in England who can grind cam followers. Keith will be re-grinding the followers for all the major suppliers out of the UK.
Take a look at the photo below. You can see one has been ground correctly, the other ones I just touched the face a little bit to give you an idea at how out of true they are. If you look closely, none of them are consistent across face of the follower. They are all but dead flat and even then the radius of the faces aren't even across. They are off centre. If left as they are, they won't spin in operation and will just hammer away on the cam. This can be checked when the motor is assembled and the tappets are set. Rotate the motor by hand. The push rods should rotate. With my cam and followers, the push rod rotates over a 1/4 turn on each revolution.
