Where to find O rings on Valve Cover Caps?
« on: January 29, 2018, 05:42:38 pm »
So I'm having a hard time sourcing some good quality replacement parts after my top end rebuild.

(1) O Rings for dowels on Valve Cover Left + Ride caps

FYI this is for a 1976 CB550.

Go to your local NAPA store they have boxes of o-rings. I buy most of my replacement o-rings for my bikes there. They are close enough for the cap usage.  Internal engine usage maybe not.

FYI they are the same cap and o-ring that is used on the ST1100 rear differential filler.
