Tried to cut to the chase in the subject line. Normally I pay attention when I disassemble any part but I've been distracted recently so I 'just did it'.
When I pulled the headers to install a centre stand (as per AF1 recommendations) I just dumped the spacers in the parts tray. Now, time to reassemble and I 'assume' the flange on the spacer faces out. I'm not keen on assumptions. (I check tire pressure before a ride rather than assume it is correct.)
Do the flanges face into the block or into the exhaust retainer?
Thank you for your collective sharing of wisdom. (Mocking the newbie is entirely within my expectations)
