Re: Yong Xing
jasonh kindly directed me to a wonderful site that gives a blow by blow account of how to fit, but I've run up against another seemingly unfathomable problem.
'Reach into the space below the clutch lever and
spin the small chain sprocket with your finger.'
It doesn't spin. This appears to be because it's in gear and I don't know how to get it out of gear. I've fitted the cable and springs correctly and the two controlling levers I have operate ( one takes it from 1 to 3 and the smaller one takes it back to one again) but this sprocket seems to be constantly engaged.
