Removing cylinder head cover

Thanks for that - will look into Ivanising.  The tapping is noty proviing very sucessful - I think tap I have may be a bit worn as its taking huge pressure to cut (and I've checked it's straight) that I think if I try any harder it will snap..  So may have to go buy a good one or go for the Holeshot kit.  Or even an M7 which might cut itself in without tapping - a bit of a butcher job but with some loctite it isn't going anywhere.
