Hey everyone,
I have a crack in one of my valve tappet covers. Coincidentally, this cover is placed on a cylinder that is misfiring (but this could also be due to a clogged idle circuit in the carbs - I'm adressing that now).
I was wondering if this broken valve tappet cover has any influence on the performance of the engine. Of course I understand that oil could leak out of the engine because of this crack, but are there any other influences? I don't know if the camshaft and valve area of the engine should be at a certain pressure and this crack prevents that, but that would have an influence on all cylinders...
Does anyone have an opinion about this?
Kind regards

No chance of any connection with missfire

I’ve got a spare valve cover ( the better type with pegged rocker shafts ) if you are interested.

Just a thought
Are you sure it's a crack that is visible on both sides of the casing & not an internal casting mark?

If there is a crack I would be worried about water getting in. Rain or when washing the bike. Not good inside your engine. 😖

I think he is talking about the tappet adjustment cap? dont think it would affect the running.
