Actually two questions: I have just pulled the rear head on my VT1000CS Sabre to clean it's filthy exhaust valve, (successfully too,) and now I am told to pull the front cylinder head cover as well in order to observe it's cam marking so as to set properly the back cam shaft. OK, but won't that affect the head gasket on the front cylinder, which cylinder I was going to leave alone? Does simply loosening the head cover nuts and bolts mean that you now have to pull the head as well and shell out another $25.00 for an extra head gasket? Maybe I just aught to resign myself to doing both heads. Also, these Honda head gaskets don't require any mounting sealants, do they? Thanks in advance for any answers.
