Clutch, cam gear etc on.
Piston, rings, cylinder- on.
Sprocket, magento, flywheel- on (final timing to be done.
I have the head ready to cut the seat/lap valves. But then I found I did not have a pilot shaft the correct size. It has rather large (for a 250) diameter valve stems. I had some HSS rod- but not really tooling to cut that. Plus no way it needs to be that strong.
I didn’t have any regular steel, but did have some brass. I figured as long as I am careful that should be fine for light cuts. I will check it out. If I notice any issues, I will order some steel rod. None of the ‘standard’ pilots for my valve cutter are correct, I would have to get one of the expanding type. Those are quite expensive and seems a lot to do two valves.
