Anyone know how I remove the steering stem lock from a 1973 Z1 900
I've read the manual and it isn't shown and I don't want to break it. Thanks

Kerry there is a wee grub screw behind the brake splitter it's hard to see and hard to get at, use plenty of WD40 and losen it right out the full way, it is a real pain to release. paitents!!!
