Hi all, new member, looking for some info/knowledge on c removal. My 2015 1100 RR started a horrific top end rattle suddenly the other day, strongly suspect busted valve spring. Engine is very reluctant to turn manually, I'm guessing, the spring has disintegrated and is now stopping the bucket from being depressed. So don't want to turn the motor , but do need to remove the heads. Can it be done with the cam sprocket attached ?
