Hello all, new to the xs world. Just picked up a '72 project and am having trouble identifying a couple ports on the engine. I have searched high and low on the internet and cannot for the life of me find out what they are for. The ports in question are located on the cylinder head below the intake ports. Attached pics for reference. I also received 2 spare engines with the bike itself and neither of them have the ports in question, however the previous owner did say they were a later yr production. Thanks in advance for any direction
