I took apart the topend on my 1967 Atlas last night to make sure all was ok before assembling bike and riding...The PO said the bike would smoke after warming up and he thought it was head gasket related...He had done a complete top and bottom end on the bike and only has about 70 miles on the engine..When I removed head and cylinder, I found that the cylinder has a spigot at the top and the head has a recess for it to fit into...I placed head onto cylinder without gasket and can see that there is too much clearance for the head gasket to seal....I am not sure what to do to correct this...I thought about filing the spigot to lessen the clearance but not sure if the spigot needs to seal against the head or not..I also got some rings with the bike that fit into recess of the head to allow use of newer style cylinder without the spigot...Another thought is to have the spigot milled off and use these rings with a regular head gasket....Any input will be appreciated as always..
