Exhaust rocker adjuster nut falls off!
CB250K0 1968
As it says…
Okay, a bit of background, as obviously I’ve created this issue.
Points case had a leak. I removed it, fitted new home made gasket and new o rings to rocker arms.
The o rings were the new version according to CMSL, David Silver etc.
The nut didn’t just undo, it came off; inlet one not tight either.
Okay, so let’s look at history.
I made a gasket. Could be a little thicker than the one that came off.
I fitted new revision o rings. As I ordered the originals and the ‘new’ version, nothing wrong with spares… I thought (imagined) that the new ones were the tadiest of tads thicker than the originals.
So, even with a ‘thicker’ gasket and a ‘fatter’ o ring, the adjuster still went through the nut fully. Still fell off after two rides.
Any thoughts?
I’m at the point now of locktighting, nylocking, serrated washering the damn thing in place.
Answers on a post card please.
Thanks.
