Headstock bearing play
Pretty sure that's what the issue is. Don't have the means to get the bike's front wheel off the ground to check, but holding the front brake on hard and giving a good shunt, there's visible movement and it doesn't feel right.
Don't believe it's wheel bearings, discs or pads. It's not enough to make riding uncomfortable, but enough to know I should do something before it gets worse. So, can this easily be rectified without removing half the front-end (again)? Can something be nipped up? |

Re: Headstock bearing play
Should be an adjuster under the top yoke. You'll need a C spanner to tighten it

Re: Headstock bearing play
If you can see movement, then that's definitely the problem - usually you feel it but can't quite see it. Yes tighten it up and see, but look out for a notchy feel esp with the bars centred - when the bearings are loose there's slop in them, unlike normal, and the balls will hammer the races and make dents, and then they're scrap.

Re: Headstock bearing play
Sosha's quite right, as are the others who've suggested / offered assistance. It's very easy to overtighten headraces when adjusting them, this leads to the bike weaving slightly as there's a little friction stopping the bars straightening up perfectly. It will also dramaticly reduce the life the bearings have left.
Loosen the bottom yoke clamps off, then the top steering stem nut, then tighten the ridged nut underneath the top yoke. Tighten it untill there's the smallest amount of resistance. Ideally you want there to be a little play in the head races until the steering stem nut is torqed back up. Don't forget to have a bounce on the front end, then do up the bottom yoke bolts. Jambo

Re: Headstock bearing play
The issue seems to be slack not tigth bearings. You don't need to slacken the pinch bolts to adjust it - maybe the top ones as the top yoke sits above the adjuster.
