Cb550 Exhaust Valve Guides
« on: May 10, 2023, 12:54:10 PM »
Hello yall!
I'm here asking about either sourcing or working around finding new Exhaust Valve guides for a 1978 CB550K. The ones currently on the bike allow the valves to move considerably and need to be replaced, where my problem lies is with sourcing them. I can find loads of Intake valve guides but much less Exhaust. Can I use the intake Valve guides on the Exhaust side? They measure longer so I figured I'd ask about that possibility. Any ideas on where to source any?

In bronze guides, they are often (not always) the same part.
