7.48mm shims?

[NickLHG_imp]

Hey guys gettin close to doin a valve adjustment (at least that’s my guess) hearing some noises near the valves. Figured may as well giver a look.

My drz currently runs 7.48mm shims does anyone know off the top of their head what the cb1100 dlx uses? And can someone explain what the different shims are, such as between 7.48, 7.5, 9s etc. not thickness but the diameter perhaps?

Thanks guys!
