Honker Welcome to the family. Yes some more info would be nice. From memory you loosen up the top yoke and screw it down then torque up the top yoke again which locks it in place. That's if it is the chrome dome nut you are talking about. And when I say loosen up the top yoke I mean the one nut that sits in front of the tank on the yoke. Careful with it as you can end up chipping your paint work. Regards Joe.
thanks for your reply.No not crossed threaded, when you push nut into the york it seems to close the thread so you cannot get a start on the stem
Yes the chrome nut that goes onto the stem. its almost like when you push nut into top york it makes the inside dia. of the nut smaller
Smilinjack was spot on had hammer the shit out of it to open the gap, stem nut goes through now. Many thanks Guys
