After removing and shipping my right (throttle) side cylinder head to Bob's for repair ( spark plug insert), I noticed the adjusting arms on my rockers seemed asymmetrical. I just adjusted the valves on my remaining cylinder head and it seems completely symmetrical. Is it possible for the rockers to bend? I've attached a photo. I seems hard for me to fathom, how hardened steel could bend like this without extreme heat...seems like the push rod would bend first. It's completely straight. Does this look bent?

I dont see a picture but I

I dont see a picture but I have heard of rocker arms getting bent. And not necessarily on these engines. Is it possible someone replaced the bent push rods? it appears there has been other problem with this head.......

Hope this posts... it seems the adjusting screws are slighty cock-eyed? No?

Does the ball of the adjuster

Does the ball of the adjuster fit the push rod OK. They looks good to me. If to straight they would interfere with the mounting bolts....no?

No, there's nothing wrong

No, there's nothing wrong with those rockers. They look fine to me.
Search for pictures of BMW motorcycle rocker arms and you will see that they are angled like that.

These on Ebay

This was easier than removing a valve cover from my bike and taking pics.
