Anyone know the recommended torque setting for the bolt that retains the front sprocket? I'm guessing it will be the same for all our 400s, but mine happens to be an NC31. I trawled through the manual three times yesterday and concluded that it's just not given.

Also it's the first bike that I've worked upon that doesn't have a fold up tab washer or another retaining feature. The rotation of the sprocket will undo the bolt too! Unless mine is missing something....

Hi, mine didn't have a tab washer either, will check setting on torque wrench...
