One of those heads will fit easily. The other one will be most difficult!!!

I started assembling the parts of the head. the old bearing was folded with a case. They probably couldn't buy a bearing in inches.

I cleaned the drain channel and want to try to use covered bearings. this method should retain more oil for the camshaft. I'm just afraid that the 2 drain channels won't have time to drain the excess oil from the head and the motorcycle will start to smoke.


.
have you ever used covered bearing heads for 4F ??? can i tell anyone have tried it?

the camshaft will float a little in the oil and the excess oil will be discarded to the valves. From there, it should drain through the canal.

I just don't know if the oil dosage is not excessive in this model and then it may be desirable for the oil to drain through the bearing

most valves seem to be fine. two seemed damaged to me, so I replaced them. I sand them with a paste and fold the upper divorce

I have ground the valve seats, assembled the springs and will wait for your advice on whether I can keep the camshaft bearing covered or whether it is necessary to remove the ball cover.
