Ha, some great replies. Cheered me whilst I been trying to get this fecker off!
For the life of me the ba*s*ed wont move. In its 'natural state, when you hold the outer ring and turn the key, then turn the inner barrel till it stops, are you supposed to just pull it up, cos it aint gonna budge!!
Does the standard one screw off or has that a bayonet fitting?
Thanks All.
Standard cap is a bayonet - 1/3 turn anti-clockwise to remove. I believe (but stand to be corrected) that the TT cap uses the standard rocker cover fittings so should remove in the same manner (once you've got it to unlock of course
).
