    ive got a 78 xs400 sohc engine. And after I finished up adjusting the valves, I snugged up the last cap and it broke clean off all the way around. Cap litterallly fell to the ground and I could unscrew the threads out of the hole by hand thankfully. What are these technically called? I might as well buy a new set of 4 if I can. I’m assuming they are just getting quite old and that one may have already been cracked before it broke.

    I already tested all the ignition components, cleaned and gapped points, so All that’s left is to get new bolts and plugs, so I figure I can just get everything at once. I still have the timing left to do.

    My stator cover also has cracks around all the bolts. Ugh
